troubleshoot sinked phone without screen - Android Q&A, Help & Troubleshooting

Hi,
My brother dropped his Archos Diamond in a bath...
The screen doesn't work but when I power on the phone, it vibrates.
I'm not sure it's the screen so I don't want to buy a 50$ screen for nothing
Because maybe it's the screen connector, or another component before that.
I entierly disassembled the phone, but nothing looks bad.
It seems I can't use ​Android Control to see the phone screen on PC
Because he didn't enabled USB debugging, except if I can flash it with a rom that has it enabled but I don't know where to find that.
Is it possible to connect a screen not made for this phone if it has the same connector ? Are LCD connectors standard ?
Any ideas ?

Problems w/ replacing LCD

So I cracked my LCD screen, bought a replacement, opened up the phone w/ little incident (man they really do cram a lot in there!) and I powered it on.....
the screen is just white, if I fiddle with the connection at where the LCD connects into what I believe is the digitizer I can kind of see a keypad button layout.
What do these symptoms describe and does anyone have a link to the service manual?
Thanks in advance for your time.
I had to replace the LCD on a wizard so here my experience... Make sure the two data ribbons are inserted securely. Also, before you power on, plug your hermes into your computer (assuming your computer is on and logged in as an admin) via USB (this sounds weird but I had to do this for some reason....) and then turn on the wizard.
If you still have a problem, you may have damaged something more than the screen.
Good luck.
Ok I will give plugging it in a shot.
Before you plugged it in what did it do when you powered it on?
anyone else have any input on what the issue could be?
It could be wrong LCD. There are two types of LCD for hermes/wizard with same connector but they are different. One is with gold flex cable, the other is with black flex cable. First one is most popular on wizards, the other on hermes. Check what was the color of your previous lcd flex cable and the new one.
Instructions
Can anyone post the instructions on how to take the lcd apart ?
I have gotten this far

I'm a bit afraid to go on without instructions
Here is the lcd I got

[Q] can i use my NT while usb is plugged in

Hi,
i have a NT , when i plug in the cable to my pc it shows he usual USB mode.
is there anyway to have it in usb mode but be able to use the tablet at the same time ? in other words get rid of the damn pop up and let me use it while its in usb and charging mode ?
thanks
you could try disabling automount... maybe the USB window is triggered when the SD is mounted for computer use.
That is absolutely correct. If you don't know where to find automount, it is accessible through the nt hidden settings app.
ive also been seeing a weird issue , ive done that in the past , but when my tablet is connected to power / computer usb cable to any power source my touch screen is funky , when im on the lock screen i can do stuff , i can pull the bar over to almost get it to unlock but when and if it does its funky , i just kicked it out off of auto mount and i have what i want except touch screen is not actually working , if i unplug it from the cable the screen works ,
any ideas ?
You could also try "ejecting" the device. That might put it in charge state and allow you to continue using the device.

I haven't noticed the "funky" screen on my NT, but have experienced it on smartphones in the past and it was associated with a noisy charger. Try using different chargers and see if the problem gets better or worse.
ah yes you have a valid point i have two NT's one for me and one for my gf hers blew a charger and we had to have B&N replace the usb port receptacle already , had it less than three weeks. I will try it with her usb cable and see what i get as they changed the whole assembly and if it does not occur with her new cable i will get them to exchange it before the 1st ..

[Q] HTC White screen help or smash with large spoon?

Ok here is what goes on with the phone... When its off and you connect the charger or usb data cable the phone wakes up and stays on the htc screen. The rainbow screen displays serial and not usb (even though I swapped the entire case from my wifes mozart phone, which did go to usb from serial in rainbow screen) so the port/ribbon cable cant be faulty. Tried hard reset with origanal 8gb card, tried 16gb card swap and hard reset too.
It goes into usb host mode when camera and volume down button and power buttons are pressed. So my question is this... I can buy a y cable debrand/flash from a well know auction site, but dont know if its a waste of £20? As my phone wont go from serial to usb in the rainbow screen I cant reflash/debrand, does the y cable debranding do the same thing as ansars rom install? Been trying for a week now.
Thanks all... just looking at the big pan spoon now, it will give it more than a scratch I can tell you, so expert replies only as outcome irreversible!

How to make usage of a s3 with broken display?

Hey guys,
i just found my old s3 i9300. the problem is that the display is broken, if turned on, it does not even light up the backlight of the lcd. the phone itself turns on, i can use the phone as a usb mass storage and the keys light up when i press the power button.
i searched on the internets for a lcd display but it seems to be expensive and hard to fix. but before i throw it away i thought maybe i can use it to give my TV a nice interface, if i am able to mirror the screen via mhl or something. would that work?
best regards
you can buy an mhl cable for connect your S3 to TV or monitor with HDMI interface...it should work

Blank screen and no usb connection

I have a problem with my LeMax 2. I was using google camera for some picture taking, and all of a sudden phone shuts down. I connected it to the charger, thinking that the battery is dead, but all I can see is backlight, without anything on the screen.
then I connected it to a computer, and there was a popup that said: "the last device you connected to this computer malfunctioned". it seems that USB cable is burnt out. I changed the USB cable, but the same error occurs.
The strange part is that i get notifications, I can locate the phone via Find my device, but i can't see anything on the screen, only i can see a backlight. PC does not recognize it, i tried Linux, win10, win7, USB OTG. i ordered a new Dock Connector Charging Port Flex Cable https://www.aliexpress.com/item/Original-New-Dock-Connector-Charging-Port-Flex-Cable-For-Letv-leEco-Le-Max2-Max-2-X820/32828762033.html?spm=a2g0s.9042311.0.0.116b4c4ds9GGuN, and changed it, but the problem persists.
i can only see backlight, the phone can be located, the notifications can be heard, but USB is only good for charging, even after replacing it.
Does anybody have some idea how to revive it?
Heyyo, hmm does tapping the power button allow the backlight to at least work? Please rest that in a dark room to see if you can notice the backlight.
If not? It could be a hardware issue... You could try heating the device with a heat gun and then using a suction cup or screen seperation tool and then check the connection of the screen to the device and ensure it is properly connected.
There could be other recommendations if someone else also has an idea
Yes, the backlight works. I opened phone, changed USB port and checked the screen connection. Firstly I thought that USB is fried due to some weird power surge when connecting the charger, but after changing the USB, it is the same.
The next thing that came to my mind is that USB connection on motherboard is fried. As I said, the phone charges up, but when connected to pc, it shows that device has malfunctioned. The screen has backlight, as far I can say it registers a touch, device finder can locate it, sound works...
