Re: Sony x930D , half screen grey bars
How long does it take to discharge the caps normally? A few hours or a day or so?

Re: Sony x930D , half screen grey bars
If I just disconnect the board, and then mess with the tcon and disconnect the ribbon cables, do I even need to discharge that filter cap? I dont want to overcomplicate things here or burn some trace out trying to discharge it.Comment

No, it's ok to unhook the powerboard from the rest to clean tcon, just don't touch powerboard in those high voltage areas and unplug tv from power unless you are measuring voltage.Last edited by nomoresonys; 07-22-2020, 03:10 AM.Comment

Very sensible to be cautious, after all you can't watch tv if your dead.

It'll look like a hazmat operation to fix a t con board. Watch after all this, it be a bad panel. FMLComment

Re: Sony x930D , half screen grey bars
Whats weird about this is no where on google can I find a similar picture of something happening. The whole right side just looks like a test pattern. All the panel failures look like small lines, and some look just plain garbled.
This is just like the whole right side is a test pattern, I mean I think its hardware but just a strange sorta thing going on.Comment

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... -
Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same... -
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... -
I have a Sony Smart TV XBR65X900H that started to have horizontal lines on the right side of the screen (see attached picture). When I played video on Youtube green horizontal line at regular intervals(1/4") across the screen.
I replaced the T-Con board but the lines are still there.
I believe this issue is from the Main Board. Before I replace the Main board, I wanted to seek advise if this is the problem from the Main board or something else?
Thank you for the help.... -
The 55" LG has been in the basement for a few months without being used. Turned it on yesterday, set came on as it should and showed a complete screen for about 5 seconds (was on a broadcast channel but no antenna was connected), then the screen went mostly dark with about 1/3 of the screen on the right lighting up with brighter lines in that lit part (sorry, no pictures of that). Power LED was cycling too, preventing the TV from fully powering up.
Pulled the back off, all boards looked OK. Pulled the LED connector, turned the set on to see if it would power up but I don't belive it...
