[SOLVED] JY3066 always white screen problem - MTCB Android Head Units General

hi i have JY joying 3066 for Toyota corolla 2008.
i time i started the car and the screen was white. i could still hear but could not see anything (full white backlight screen).
i had to go somewhere and had no time to fix it so after driving for about an hour - the screen came back to itself but the system did a hard reboot ( all settings was wiped).
since then all was fine for about 2 month and now it happened again.

I plugged it in 12V5A power in house for several hours to fix itself but it still stuck on white screen.
to be Clarify- white screen is also on boot logo and on recovery mod
does anyone knows how to fix it?
thanks in advance.

after openning the device by removing one screw at the back and two screws at the sides, then you remove the DVD drive by removing 4 screws.
then 2 screws at each side to remove the screen and you need to disconnect and reconect the big white cable from the board to the screen.
this works for me

Wierd Line showing on the Camera and even on pics :(

I just flashed a at&t Tilt with the original HTC ROM :
RUU_Kaiser_HTC_WWE_1.56.405.5_radio_sign_22.45.88.07_1.27.12.11_Ship
I am seeing a wierd thin orange line (vertical) across the camera screen. This also shows in the pics. Has anyone faced this problem ?
Mine has had this problem for about 2 months now, I have a vertical orange and horizontal gray line messing my pics up.. I guess the only way to fix it is through warranty, tho atm I can't afford to lose my Kaiser for a month.
Funny thing is that the first time it happened, it went away after 2 days, and then came back on in a week, never to go away again
Several radios, roms etc tested, it's an internal problem, since it's not the lens either
i've the same problem... sometimes the lines go away, but I think I'll need to get it repaired....
Just so everyone knows what we're talking about:

I get the same issue, always 2 lines - one vertical, one horizontal. Soft reset sometimes fixes the problem, sometimes it doesn't. It comes and goes. Very strange!

1. Why in the picture 3(shows after picture number 1 and number 2), It just shows me a blank screen for about 10-15 secs?
2. it also has annoying taskbar appear right after the picture number 3, why?
FYI, I has 75% Program Free, 45% Storage Free and 25% Storage Card Free
And I also have this keyboard annoying problem. By the first time, the 'ok' button is not really responsive.
Then the 'Bckspc' button and now the left side of 'Space' Button not responsive at all.
Would Sony Ericsson cover my X1 for this failure? I still have 2 week waranty.
FYI, I really take care this X1. No scratch or anything. I always carry this X1 with pouch that has no magnet.

Should i flash to stock and go to t mobile?
Go back to stock and test the s pen again. Make a backup of your ROM.
If it's the same in Stock, then you need to get the phone replaced.
I had the same issue when i got the phone. I had to have it returned for a brand new one due to this. Sometimes the screens pressure sense fails. On my replacement, there were points where i would pull out pen and try to screen shot and the screen would flash as if capturing a screenshot and then no options provided. I thought i was going to have to return another one but then the new update fixed the issue. I dont know why lol. But my second device seems to be working right now. Call tmo and tell them whats going on. If its within the 14 days, request a brand new one.

No backlight after screen replacement z3 xperia compact

I changed the screen because it cracked. When I first tried the screen it was fine and it worked. Then after a while the backlight didn't work. The screen works and I can barely see things on the screen, but backlight is not working.
I read there is a fuse that helps fix this issue but I don't know if this will help. Here it is: http://www.mobilerdx.com/2015/03/sony-xp...

It's the first time the phone is opened and I never thouched the fuse because it's underneath a metallic plate, which I didn't even touch or moved. So why would I have to do something with the fuse if I never did anything to it and the screen was working when I tested it?? It just stopped working afterwards for some unknown reason.
The phone is on, because there is the blinking light. So, do you have some suggestions??? Should I actually try to add a jumper on the fuse??
Thanks.
EDIT: I remember that when I was about to close the phone I put the screen upside down, and it was when the screen backlight stopped working. Is this some reason why the fuse could have been damaged???
Thanks
Hello, I have the same problem, any luck?
Same problem here, I replaced the screen, the touch screen works. I can here clicking when I touch the screen, and I also feel vibrations. But the screen is blank. I tried my old screen (cracked) and the same thing happens, it's blank.
Any fixes?

Problem with my head units, not work

Hello
I have a problem with my head units.
The device worked properly only two weeks.
Now the device works only a few minutes after switching on. After a while the picture will freeze and the Artifact will appear. More and more Artifact until the display turns into one color (white or purple on the pictures). Then the display turns off completely. The radio can still be heard from the speakers, the touch screen and touch buttons are not working.
When I press the reset button, it resets the device but it will not turn on.
It will turn on after 2-3 hours of parking
Has anyone had a similar problem and can I give you a hint as to how to fix it?
Regards and sorry for my poor English
