Hi,
My HTC is giving me problems. The screen has become yellowish.
Earlier the screen used to become yellowish for 5-10 mins and it used to occur in two weeks or so. But now the phone has permanently become yellowish. I am also attaching a picture along with this thread. As you can see, the areas in the pic which are bluish is showing the true color of the background. Rest of the screen is all yellowish.
Can someone help me with this problem.
Best regards,
MOhit Goyal
Looks like a faulty contact from your Motherboard to your screen (bad connector, bad flex-strip or something like that)
IMO you need to send it in for repairs.
I have had the same with my p3300, but was able to fix it myself (connector was not completely pressed down, had come loose)
Hardware problem?
Do you think this is a hardware problem?
Why I doubt that is because:-
1. Whenever I touch any place on the screen for opening an application, the area shows the actual color, but if I just touch the screen the colours doesn't change.
2. Usually the phone starts displaying the correct colours after a restart
Should I take chances and reset my phone or something?
I'm having the exact same problem every now & then (often occurs when I keep the phone in my jeanspocket) A light tap on the screen often helps. Had it in for repairs earlier, but they only re-flashed it (!) So the problem is not solved
What to do now?
I am not able to play any game. I hate looking at my phone. It makes me so angry.
How do I get it fixed. Its the fourth consecutive day with the wrong colours.
Someone please help.
Performed a hard reset but still not working properly
This is not happening. I performed a hard reset thinking that it might just work but it did not.
Can someone please help me here.
Of course it is a hardware fault. Send it in for repair - or repair it yourself
I think is a virus or something else, because has happened to many people lately.
I also had the issue as pictured above.....and exactly as described in the first post.
It began to occur about three weeks....and gradually was getting worse.
Its getting worse
Again I am doubtful that its a hardware problem.
Now, I am not even able to open anything on my phone. I keep getting thrown back to the main screen. No matter what I open, what application I am using, it just keeps throwing me back to the main menu.
In addition to that, even when I am not using the phone, it just keeps flashing. I lock it and the screen turns on again. Its like the phone is getting used every second.
I think its a virus. Does anyone know any anti virus solutions for HTC HD2?
Thanks,
Mohit Goyal
i got exactly the same problem - check my photos here http://forum.xda-developers.com/showthread.php?t=716002&page=2
i donth think it is a virus - why? - becase if it so the virus should go when you reflash the rom or flash a new rom - i douubt also about the virus but when install new rom the color issue still existig.
i sent my device to the dealer for repair and i will apdate you about the real reason when i got the answer from the dealer.
however, the same issue happened before to one of my friends and the device was out of warantee - he took it to a repair shop and they told him it is a kind of default in the mother board.
this time we will get dealer answer so lets wait.
thanks
a member in other forum advised me to use the attached cab which solve a similar issue in Blackstone.
but it is too late for me because i returned the device to the dealer
however- other member faced a similar issue and the dealer told him it a default in the motherboard.
Send in for repair......

Listen to the others... You need to send phone in for repair... My phone use to flicker on and off to the point where I couldn't call or use.... I sent to be repaired and they replaced the mother board, but didn't fix my other problems (phone will not turn off and when u put in battery phone turns on on it's own)..... I would send in for repair.......................
htc contacted me an inform me that the reason was the motherboard
yea its the motherboard isue i droped mind and d screen has changd its colour to yelow blue and sometimes wnt wake up aftr remvng 4m poket.gave it htc repair center they said a socket or conector has a problm whch cnt be repaired and so mothrboard needs to b changed.motherboard cost 8000rupees/190dolars whch is **** expensive for repairing
I had this same problem and read on some other forum that you're supposed to "flex" the phone. So I bended my phone a little (the top and bottom backwards, be careful the screen also has glass in it) to try to get a bit of a curve in it and by god ...it worked!!!!! The screen flickered and then the yellow screen was gone!!! I'm so glad because I mailed Htc two days earlier and I still don't have a response from them. I hope it works for you
Just to confirm... The same thing happen to me its either (A) the cable from MOBO to Screen came loose usually by flexing or bending the phone which can happen in someones pocket. (B) the cable connector came loose by same methods (C) MOBO went bad usually by same methods. Either way one should it in for repairs or crack it open and see for your self.
I got same problem before, it happened when the screen is moist. it looks like there is an absorbent layer behind the screen which got damped. try drying it.....found article to contained the unit in a seal container with rice overnite for drying electronic gadgets, and see the result.remember to take off the battery. good luck.
I'm having problems with my phone. My warranty is already over btw. My phone is having a black screen, but the touchscreen works. The rest of the phone works. Vibration, keypad buttons etc. I disassembled my phone, removing the front screen (I think its the digitizer/touchscreen) with the connection. Without the front screen, the phone display will light up and I'm able to see everything, but I cannot touch or move anything on that display. I presume its the LCD screen. So now, whenever I connect the digitizer to the phone, the screen of the LCD turns black again. Now, if I loosely fit the connecting wire to the phone from the digitizer, both display and touchscreen will work. But if I connect it properly, the screen turns black again. Correct me if I'm wrong in the screen names. I need advice on what I should do. Thanks!
the same problem for what i asked advice before...but i have sent it for repair some 20 days ago and its still under repair...mine is still in warranty...so i didnt fiddle with it.
what charger you use? i think my display went dead bcoz of the samsung charger...now i swear not to buy any sony handset ever...never faced a problem with nokia sets for over 10 years...i think i overdosed my handset with flashing and charging...anyway...thats a hardware problem so you better take assistance from a service centre.

I've sent to the Sony service centre. Luckily they accepted it. Same, I have never faced a problem with Nokia phones before. Still good and running. I'll never buy a Sony product again
Too bad Nokia doesn't build Android devices. If it does, I'll certainly buy one. Despite the software Nokia phones had always been the strongest. But I doubt a charger will cause such problems...
Hello all,
First of all I hope I am writing in the correct section... Otherwise please let me know.
Secondly: Something really strange is happening to my Galaxy S2.
Last year, the glass broke on the street and I changed it manually by buying one from eBay and following video instrctions. This year the touch and AMOLED part of the screen cracked (I don't even know how). This time I decided to buy a Galaxy S4, as I didn't want to "invest" anymore on the 2-year old smartphone, but I kept it. Later this year I decided to fix the S2 one again, and so I ordered a replacement screen (which costed a whopping $105!!!) and changed it. To my surprise, although I checked all the motherboard connections more than twice, the phone turns on, the Welcome Screen (configuration for first time usage screen) appears, but... The screen is unresponsive and I also can't change the volume nor turn the screen off by pressing the lock/power button.
If someone knows something about this problem or how to fix it, I would appreciate a comment with information regarding it to be able to understand what is happening.
Thanks in advance!
B.S.: I don't know if this information has anything to do with the problem, but the first screen I bought wasn't original, as it didn't have the Samsung logo on the ribbon cable, while the new one is original and the Samsung logo appears on the ribbon connector. I wonder: Is this a factory failure?
@joseguse
Thats what happest when u buy cheineese sh...
Buy ORIGINAL screen for I9100 and replace it. Thats all.

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.

thanks saxmydix, i used multiple chargers and it is still the same, i tried charging in another house in another area, still the same problem occured, so i doubt it is the problem with my charger.

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

It wont be 100% of the cause but will affect performance of the screen.

Yes, using a non-mains connected charger will be sufficient for the test, like your power bank for example

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.

Hi Nidhal
I have replaced whole screen with frame, but it seems to be used one (ordered from Aliexpress). It might be the case, I have two complete screens with same issue on my desk, but I dont know how to test them

you have to test each of them separately
take out the mainboard from the old chasis (frame) to test on the new lcd you bought (carefully unplug all the connectors)
then, connect the lcd and digitizer connectors to the mainboard, connect the battery too, and of course the power flex cable should be connected.. power on the phone, and see if the display lit up, then if the touchscreen works... and do the same with the second one you have and i hope you will have a working one al least
watch this video tutorial to avoid any damage
https://www.youtube.com/watch?v=hrOQoOSbldU&t=1s
and BTW, never buy these type of parts from aliexpress! would've been better from ebay or amazon because you'll be covered with warranty in case the part you buy is defected, and for that, you'll get a full refund or ebay will refund you if the seller won't
good luck
