Picked up a dead bravia with 5 red flashes. Found two bad fuses one on the PSU and one on Tcon replaced both and Tv came on. Unfortunately the picture is bad. Will a bad TCON cause this or maybe the dreaded tabs?

Re: Sony Bravia KDL-52W3000 Bad Picture
I know the screen shows a black spot in the lower left corner but at times the whole screen is black and white pixels with no black spot in the corner. -

Do you think the rubber under the bonds would be worth trying?Comment

NOTES: Do not run the panel more than few minutes without the frame attached (the frame is used for heatsinking the IC's on the flex board) or you will damage the IC's on the flex cable.Last edited by budm; 05-23-2013, 07:14 PM.Never stop learning

Re: Sony Bravia KDL-52W3000 Bad Picture
Ok thanks for the tip about the frame being the heat sink, I thought the tabs felt pretty warm.. Ok so when I manipulate the far left on the top tab the picture changes so it is the problematic tab. I will try the spacer and see what happens.Comment

Re: Sony Bravia KDL-52W3000 Bad Picture
Ok did the rubber spacer thing and I got it pretty good. But as you can see in the picture the left 1/4ish part of the pic is a little pixelated?Attached FilesComment

Re: Sony Bravia KDL-52W3000 Bad Picture
It looks like you may not get all the connections on the tabs, it kind of hard to do since you have to keep pressing at many section of the tab to see if the problem will go away, but you have to do fast before the ICs get to hot.Never stop learning

Re: Sony Bravia KDL-52W3000 Bad Picture
Well sad to say it looks like a lost cause at this point. I tried manipulating the bad tab as many ways as I could but could not get any better than the pic above. It only continues to get worse. Guess this unit will be for parts now. Can't win them all I guess. On to the next one!Comment

Hi,
i want to repair a Sony KD-75XF9005 TV that initially only showed a grey picture.
Backlight seems to work, Sound (Setup menu after reset) works.
If i dissconnect the left FFC cable from TCON to panel i have half a screen on the right. If left cable is connected always only the grey screen.
Interchanged the cables, its always only the right side that is working. Always grey if left side is connected.
With my small knowledge i would think at least the cables are good.
Can this happen because of a bad tcon board?
Or is it always a bad/shorted... -
Hello, Last week I bought the 50" Sony X80j tv everything was working fine, untill I plugged the tv in a ups power supply 650va the tv remote control became unresponsive and the TV became laggy after a while the picture quality isn't the same as before the tv seems less brighter and the picture is somehow blurry, people's faces don't look as natural as before, there is a mini orange-pink tint to the edge of people's faces especially in NETFLIX Dolby Vision like in One Piece ep1 Alvida skin tone, my intention was to protect the tv but something went wrong I checked the ups with a multimeter,... -

Previous owner said TV just went blank one day.
They attempted to open the back panel and yanked the power connector off the power supply in the meantime.
Easily fixed that and got the TV to turn on. Backlights come one with everything connected. Good Sign.
The mainboard shows signs of life (red light on digital audio out is on) but that's about it. Good Sign.
There is not blinking LED and the most importantly there is LED response and sound when I press the MENU button on remote control. GREAT Sign.
I just downloaded the Sony KD-75X7800F Service Manual and... -
I was watching youtube yesterday, when I paused it to go to the washroom. When I came back, the right side of the screen was showing half of the youtube channel and the left was black. I powered off/on the unit with the remote and now I have no picture whatsoever except for the bluish backlight. I did the factory reset (power + vol down), and now I when I power on I get the startup music, backlight but no picture.
I took the back cover off, and reseated all cables but unfortunately same issue. I took some voltage measurements on the main 2 headers from the power supply board and...
