Looking for suggestions on this one, the TV can work properly but most of the time when it turns on you get a solid white screen. Tapping it on the top (ghetto I know) or moving it around will cause menus and things to flicker on the screen, and if you get lucky the picture will come up and work perfectly fine. I've tried unplugging and reseating all the connectors on the main board and the T Con, wiggling the cables near the T Con seems to have the most effect but nothing consistently brings the picture back or causes it to cut out. Does this sound like something a lose connection on the T Con would do or more likely a bad cable?

Hello everyone,
I've recently been given a Sony 8k Z8H. It's got a white screen with two vertical black bars. At times it's given me the 5 blink Tcon code. Testing voltage on the Tcon I can see some low or missing voltage. I've done a basic visual check of cables and the COF. Not seeing anything obvious. The original Tcon seemed to have good caps until turning it over. On the bottom I found maybe 10 caps with both sides of the caps shorting to ground. I thought ok these caps and likely other components on the Tcon are shorted so let's try a replacement Tcon. I just received the... -
Hi guys
strange one
I have a dead Sony 55X850D
when plug in, black screen, no front white or red LED, no back light no screen
Voltages I get
3.3v LD/power and main board
reg 12V
reg 19V
3.3v on power on pin
no Tcon on
no tcon 12v
no BL_on
I do get BL_ERR 2.0v
I tried to bypass it by ground it but still get same symptom
I did also found a possible shorted cap on main board as it is showing 10 ohms when measure with meter
or is possible the chip next to... -
To ask here... I have few devices with white screen problem, actualy nokia 2220 and some fuji? camera, and try to understand what is common problem to cause that issue.
Yes, both devices work everything else probably ok, I mean, I hear intro melody and keypress click sound, DTMF tone, power on off... all ok.
On desk is nokia 2220 slide, and I check all screen connectors and components arround it, measure voltage drop, but all looks ok. I suspect on slide flex cable, but it look ok and white screen is not interupt while flexing board, pushing conectors, and sliding up down. In attachment... -
Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
Another TV topic!!
I got this sharp TV that when I first plugged it in it showed the sharp logo and then went to the input screen. This was about 30 seconds and then it showed white screen. Now I can't see anything but white screen. This has a separate TCON and Main.
The TCON is getting 12V and several parts are as well but the VGH line is only .5Volts which I thought is totally incorrect.
Am I on the correct assumption that the TCON is bad somehow if I'm only getting that voltage or is there something else I should check?...
