Re: skyworth led tv shows white screen only when turned on
Model number?
Pictures?
Sounds like T-con fault, possibly a fuse. But, bad capacitors caused this problem on an LCD monitor I had.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: skyworth led tv shows white screen only when turned on
White screen only tells you the back-light is working and the video isn't.
There are dozens of faults that could do that.

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... -
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?... -

Hi all, I’ve got a problem I hope someone can help me fixi.
I have a Panasonic TX-48CX350B tv , it powers up ok but the screen is blank, the backlights are working, there’s nothing else though, no picture or sound.

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...
