Dead Folio screen - Folio 100 General

So, earlier today I was watching a movie on my Folio. Everything was fine all running as usual. I put it down on the table, plug the charger in and turn of the screen. Half an our later when I try to turn the screen on again its all black. I restart the Folio, same result. I remove the battery for a couple of minutes and start the device, no luck there either. Any one ever experienced a similar problem or maybe know a solution to it?
Greatful for every advice

Does the display ever turn on??? I mean, if you cannot even see the Toshiba logo I don't think that your problem is software related?
You might want to open your folio and check if the hardware connector of the LCD panel is fitted correctly in its socket on the mainboard. I inadvertently unplugged it one time, as I was playing with folio's guts Maybe, your connector just got loose in time.
However, if you are going to try and open your folio, the connector should be placed in the upper part of the device, just between the webcam and the hardware keys. Yes, you will need small hands and some practice

I can feel the device starting since it's vibrating at start-up, 'only' problem is the screen is completely black. So it's not impossible that the screen connector is loose, I just don't see how it could have happend since I never have opened it myself :O
Well, I think I'm going to crack it open tomorrow and see what I can find

Right now I'm actually quite proud of myself cuse I managed to fix my Folio opened it up and saw that the screen connector was loose, so I put it back in place and now it works like a charm!

The connector was located in the bottom left corner of the device, not upper part

Well, it seems that I might have rotated my folio at that time . Indeed, the hint was ALMOST good, even if in a counter-clockwise style! xD

[Q] Menu button flashing issue

Hi to everyone in this forum. I've recently received as a present a new toshiba folio 100, but, since I'm experiencing an annoying menu button flashing, I've thought of it as a software problem so I upgraded the folio using the foliomod1.3c and applied the rotate patch and also the 1.3c fix patch. The menu still flash with no apparent logic. I've tried to kill all applications running and it's still there. It seem to come up and down at random. I ask to all in this forum: do you believe it's a hardware issue or is a software issue? Because if it's a hardware issue I'm going to try to have a new folio from toshiba. I'm overall very pleased with the work that Dexter made to make the folio an usable machine but this flashing is driving me crazy. I use the folio basically as a portable scientific pdf reader so I need to concentrate on what I read and this flashing is really annoying. I would like very much to thank you all in this forum in advance for all the suggestion/help you could provide.

I have a request that serve All those who suffer MENU crazy button .
Is it possible to prepare application you can setting ON/OFF the MENU button
Most of the time useless button.
sometimes button jump after 10 minutes, sometimes after an hour
Usually I fix the problem by changing the settings with FolioButtons 1.1.
If you could add to FolioButtons on/off operation for menu Buttons was the best.
Hi teknoraver,
Can you add enabled/disabled menu button in foliobuttons application ?

I am pretty desperate about this issue, because none of the methods seem to help...
Right now the buttons work opposite- Menu button flashes mad and none of the other 3 responds...dont know how it happened
Just a thought- while the folio is booting up the menu button ALREADY flashes! I have zero understanding in there but isn't it a process that loads / starts early in the line?
I appreciate everyone's effort trying to solve this bug as it makes this handy tool a useless pile of crap.
I was wondering how many folio users are suffering of this crazy buttons madness.
Mine was crazy from the very beginning; I sent it back for repair and toshiba only did a firmware restore... Nothing changed at all!
It makes my folio almost unusable!
bye bye crazy buttons
After two weeks of testing and a complete breakdown of my folio100, I finally find the problem or just crazy buttons and freezing of the screen.
I drag a thickness in the screen in the bottom right corner of the screen to isolate the audio connector and it works better than a miracle again.
The only downside is that the screen comes out slightly from the slot but nothing really bad.
The thickness I put slightly too big or-1.4 mm I'll Demount next week to put a finer and I'll try to take pictures in passing.
Note however that the loss of waranty is innevitable.
Sorry for my bad english ;-)
I think it's a hardware issue and even a build quality issue.
If i hold my folio at the side of the buttons, i get the flashing buttons problem (even the foliobuttons app will not help), if i hold it at the other side, i've got no problems at all.
Do you have an animated background? Because I saw that some people had this issue with an animated background...
Hi Mshr73, nice first post indeed

seems to get better...
I really don’t want to be too quick on this, but Dexter’s 1.4 seems to bring relief to this issue - for 2 days I have been running this mod the menu button stopped flashing!!
Any similar impressions on this?

No way pal, I guess I'm in the opposite situation. It still happens to me, and sometimes I think it even got worse... well, I can always look at crazy keys as a "special feature" that no other tablet will have!!!
I just tested without thickness under the screen, with foliomod 1.4 and after a few hours I again the problem of crazy buttons.

Well, I just finished dismantling e reassembling my Folio. Following your hint, I cut a piece of paper and put it between the audio connector and the back of the screen (yes, it was metal vs metal). I'll see whether it's gonna work or not. Crossing fingers for now.
Not that I'm so confident in leaving a piece of paper stuck right where the DC input is .
BTW, did you try with a smaller thickness? Even if this is the problem, I'm wondering whether a piece of paper would be enough or not.
thyself can someone. post pictures of before and after details?
we will be much appreciated
i didn't have the crazy buttons issue this far in 2 weeks, just my home butten needs to be pressed harder. I'm pretty sure it's hardware related, i read often that users experience it when changing from an warm room to a colder one, or in regions where its verry humid(some circuit closes maybe...). so Mshr73 is on the right way as far as i can tell.

Really sorry mate, I hope it will solved this for others too...
Anyhow, it is so disturbing, that I was already considering to send the tablet back to Toshiba...
I'll try to do this weekend if I do not have too many customers. I post the result Monday.

I'm looking forward to your pictures, too... because my trial simply didn't work.
I tried with both a single piece of paper and then with 2 pieces wrapped in tape. I put these spacers between the back of the display and DC/audio connector.
In both cases, the crazy keys phenomenon started to happen after 15-20 minutes of usage.
In most cases, it starts to show when I unlock the device. As soon as I unlock it, home and menu buttons light up with no apparent reason and go crazy for 10-30 seconds.
Then, I even tried to loosen just a little the screws (I read, somewhere in the forum, of a guy who said that he solved his crazy keys and screen lag problems this way). I mean, all screws are now locked but not too tight. Well, I have to say that I don't have any screen lag anymore (I even removed the piece of paper, from the battery area, which used to solve the issue before) but crazy keys still happen. I'm going slightly mad

I handed a piece of cardboard and the problem disappears.
I think that to raise the screen to solve them but I'm still not 100% sure.

[Q] Streak 5 not displaying anything

So, being clumsy, I left my Streak in my hoodie pocket. Well, we can all see where this would end badly once I bent down to pick something up. I did, dropped my phone and cracked the screen.
I quickly went and bought a replacement glass + lcd display, and replaced the unit. But, upon turning the phone on, I noticed if I hit it a little too hard on one corner, It would restart, and the vibrator motor had ceased to work.
So I figured, hey, I'll just rebuild it again. So I took it apart. Looked through everything, took my time in putting it back together, because maybe everything wasn't fitting snug.
Now, When I turn it on, every thing is on, buttons light up, and the screen is lit up, but it is black. I never even get to the Dell logo. After about a minute the buttons dim, as if in idle. So i believe the phone still works, but maybe the connections on the MoBo is faulty? Any help would be nice, thanks.
check to see if the ribbons are snugged in place.

I agree take it apart and chech your work. I had problens with my camera and flash. It was tge connector not being fully seated
Sent from my Dell Streak using XDA App
Well, I just took off the rear cover and reseated all 3 connections, pushed em in as smoothly and far as they would go. But, same thing. Black screen. But the LED is still working...
I'm having the very same problem. This is my second replacement screen and neither displays anything except black screen with backlight on, and the home + settings + back buttons remain lit. I can hear my phone starting up and receiving messages, but I cannot see anything. I've taken the phone apart and put back together five times between two replacement screens.
Does anyone know what ribbon cable might be at fault for this particular issue? The largest ribbon cable was shipped bent across the circuit board on both screens; there is a permanent creese in both ribbon cables, but I'm not certain this is causing the issue.
Any insight or assistance with this issue would be greatly appreciated!

[Q] Digitizer issues

Hello everyone. A few months ago, my phone screen broke, and I replaced it. Ever since then, my digitizer has been funky. When I turn my phone on the top half of the screen is static and the bottom half is black. It shows a bunch of moving parts (the boot animation) then goes black. It also prohibits me from using Amon Ra which is my favorite recovery because the whole thing is static. When I press the power button after the boot animation, my homescreen is on & my phone is fine. I broke my screen again (don't judge me lol I see you looking at me with that face ) and instead of putting ANOTHER screen on, I bought both the screen and digitizer already put together. So last night I lost all touch capabilities of my digitizer, when I did swype it did the mark of satan by itself (possessed rezound?) and overall was just terrible. I opened it up, cleaned up the ribbon, put it back, and 95% of touch worked. Did the same thing today and 100% works, however, I still get the weird static-turn-on thing. I assume it's the ribbon port for the digitizer..so my question is, is it possible to clean that? I was thinking with a really soft toothbrush w/ alcohol on it but I don't wanna ruin my phone for good. Thanks in advance

Use what i do for computers. Take a new pencil, never used eraser, and use the eraser to clean the connectors. take q-tip with alcohol. brush across it, and fan it dry. about 2 minutes is good. Alcohol dries pretty quick. Hopefully this works for you.
I have been having some problems as well. I replaced the digitizer myself and the phone boots up completely fine and normal. I just have some "dead" spots on the digitizer which I cannot seem to calibrate. I have tried apps and everything. Is there anything I can flash through recovery?
Has anyone come up with a fix for this?
Thanks in advance.

[Q] HELP! Problem with my Samsung Galaxy A5!

Hi,
As mentioned above, there is a problem with my A5. When my tempered glass screen protector is fixed and when my phone is charging, my touch screen seemed to go haywire. I am holding my finger in one place but the phone detected that my finger is shaking, wildly. Besides shaking, my phone will stop sensing my finger even though it is held there.
I doubt it is the problem with my hardware because I have already changed the touch screen, charging port and the motherboard by sending it to the Samsung Service Centre. I believe the problem is due to the tempered glass (my previous tempered glass) because it was put onto another A5 and the same problem occured. Now, I have purchased another tempered glass from REMAX (picture below), and it seemed to cause the same problem again.
So now my questions are
1. Can I seek for another alternative such as Spigen's tempered glass screen protector or should I just use the normal screen protector?
2. Am I the only one facing this problem?
3. Is the problem really due to the tempered glass?
Oh by the way, my phone is running on official rom version 4.4.4.

Without getting into too much tech details i have a list of possible cause's
1. with having a additional screen cover in place and power connected your body+screenprotector create a capacitor, this is exactly how the screen registers touch , so without the screen protector in place this wont happen. I've seen this on a few Screen protectors that use certain types of conductive glue/bonding agent.
2. faulty charger or fake chargers often cause this behavior, try another charger or use USB on a laptop not plugged into mains power, if the problem is gone then plug in laptop's main power, if problem still gone then your issue is charger, if problem starts when pluging in the laptop's power then it's either ground loop or your screen protector acting as above.
3. faulty assembly when fitting screen, they didnty apply the copper back shield or the protective cloth that act's as a shield around the ribbon cables
before anyone shouts that samsung fixed it, I know and i can quote many a occasion a cell phone was not fixed right first time by the OEM
if you activate developers options and switch on show touches then repeat the test , does the display always show certain areas that register touch , if so it can also show where the bonding agent has a airgap, this adds to the capacitor effect.
finally try wearing shoes when touching the screen, if wearing shoes stops the problem get your house wiring checked.

hi darkspr1te,
thanks for ur response.
1. so it is entirely dependent on how the screen priotector/tempered glass is sticked to the screen?
2. sorry for not including the details on my charger in my post. i am currently using an official charger that i got when i purchased my previous samsung phone(S2 gt-i9100g). i tried using the A5 charger and the problem persists. will using a powerbank recreate the scenario of the unplugged laptop charging? if it is the same, the problem is still there even when my powerbank is unplugged. i do not have a laptop at home and it wouldnt be possible for me to get my hands on a laptop that i can use these few days. i tried charging my phone in another house (in another region which is like 20 kilometers away) and it is still the same. and my brother's samsung galaxy alpha do not have this problem while charging.
3. so u are saying that the problem might be due to oem? once again i apologize for not including this in the post. while i am at the samsung shop, the person in charge tried putting the tempered glass (which was fixed to my phone) onto another A5 which was there due to a boot loop problem, and it started to have the same problem. is it possible that all Samsung A5's assembly do not have the copper back shield or the protective cloth?
apparently nobody in the samsung shop knows how to deal with my problem because they have never seen it before. it took me quite some time to explain to each person who attempted to serve me and i only managed to show the problem to one of the personnel (which was the one who helped me fix my phone). i went back to the samsung shop 3 times in 2 days. in the 1st time, he changed the touch screen, in the second time, he changed the charging port and in the third time, he changed the motherboard.
as for the test, i turned on the pointer location and i keyed in *#7353#, and i selected TSP grid mode. that is how i checked the problem. and while i was there, the shaking only occurs at where my fingers are. i tried enabling the show touches option and the display do not register touches until i touched them.
i doubt it the the problem with my house wiring since it is the same with my other house but thanks for the suggestion. i will definitely try wearing shoes when i am at a different house. maybe both my house got wiring problem.
i learnt a lot from your post. thanks for your time and i hope to hear from u soon

Note on images 4 and 5 you will see the copper shield, this model does not have the conductive cloth I mentioned but the copper ground plane can clearly be seen on both the body and screen. Fake and non oem parts tend not to have this, in the body there is also a copper area which can be removed by mistake on replacement of the screen.
this is not often found in the replacement screen kit.

if it's happening at another location then you can discount this theory.
I am still leaning towards incorrect parts or assembly as this is the cause I personally see most often and i've repaired a LOT of damaged phones. As you have stated you have more or less a complete new phone if they replaced screen+motherboard.
I once repaired a phone that had been back to the OEM service center, cause of fault was copper strip from old screen touching the board, the copper slip was so small i only noticed it when it sparkled under the right light, it's mistakes like that is what I am talking about, easily missed by many.

Sadly that can only be done by removing the screen. I dont suggest you try, ive seen the disassembly video, it's tough, one time job and if it goes wrong it's bye bye screen.

I sent in my phone to the samsung store to check the charging port (which is also making some problems), and i requested them to check the copper shield.
while i was there, i realised there is another phone which has the same problem as me. could it be that all the A5 model has the same problem ? :/

I don't think it's the phone model, we would see more reports if it was, I would enquire if the other unit also had screen changed. If it has then one might assume pirate parts, no way to prove that without checking back of lcd for the oem barcode sticker. The is on possibility I only just thought of, a while back I had a client bring me a i9505 that the oem changed screen on, I just reread the emails between us and the fix was replacing the screen with a i9505 screen, the oem locally only supplies i9500 devices so they only fitted a i9500 screen, turns out there is a difference in the touch chip, I was able to prove this by attaching the touch only circuit from his old screen. No more random touches.
From this I can assume the various SM-A500 models use different touch chips. Or slightly different firmware in the chip, I have seen that before on the rock chip based tablets I support here.

The is on possibility I only just thought of, a while back I had a client bring me a i9505 that the oem changed screen on, I just reread the emails between us and the fix was replacing the screen with a i9505 screen, the oem locally only supplies i9500 devices so they only fitted a i9500 screen, turns out there is a difference in the touch chip, I was able to prove this by attaching the touch only circuit from his old screen. No more random touches.
From this I can assume the various SM-A500 models use different touch chips. Or slightly different firmware in the chip, I have seen that before on the rock chip based tablets I support here.

this is getting a little too complex for me to understand, let alone explaining it to the samsung guy. are u trying to say touchscreens from different variants of A5, such as SM-A500G is being fitted into my SM-A500F?

Yes, that's exactly what I am saying. Although it's only a theory based on prior solutions, I dont have any proof to hand other than my experience.

Battery issue

White Lines across my smart phone screen

One morning I woke up and the bottom half of my Samsung galaxy avant (SM-G386T) had a grid of white lines going across it. First time I restarted my phone it went away.
But they keep coming back and now it's more permanent, Sometimes it goes away briefly but they come back. I tried factory resetting. That worked the first time for a few hours but then it came back. and I tried it again and 2nd time there white lines where there during the factory reset.
The lines even show when I turn the phone off and charge the phone. So I believe this means it is w hardware issue
I tried taking the back planel of the phone off. I disconnected and reconnected the lcd connector latch on the left side. But the problem still persists. I haven't pulled up the screen with a suction cup. So Idk if there is a cable that could be loose on the front end or not. But Idk want to go buy suctions cup if I dont need to you.
Should note that I do have a good sturdy rubber case on my phone. but it has hit the floor a few good times.
One other thing that seems to aggravate or sometimes even make the lines go away is putting my phone to sleep and waking it up repeatedly or adjusting my brightness to max.
What do you guys think? is this fixable or do I need to replace the lcd screen.
man its simple
just press the wires of display which are providing it power & ur problem will be gone.
Its due to lack of sufficient current to display!!

What wires are you speaking of exactly. cause like I said I have taken the back off and disconnected and reconnected the LCD flex cable but nothing changed. Are there wires behind the LCD I need to get to? which means I need to removed the screen with a suction cup?
