Re: Sony xbr52hx909 rainbow lines on image
It looks like main board issue. What is the history of the TV?
What did you inspect so far? Re-seating cables? Tighten all the boards' mounting screws?Never stop learning

Hi, I have a Sony XBR-65X750D that has horizontal lines at the bottom 6 inches of the screen. These lines appear to be every other line because the picture is still quite visible behind those lines. The lines appear all the time with a few other lines above and below the 6 inch level blinking on and off at about 2 second intervals. I'm not sure if this is a panel issue or power supply/main board problem. I did replace the T-Con board without any change in the problem. Any suggestions you might have would be greatly appreciated. Thanks, -
Hello again everyone,
This is my latest mission, to try getting this Sony tv back to normal working order…
I've only just got it today, when you power it up everything is as should be, in fact it works perfectly for a few minutes then the screen starts getting horizontal lines on & eventually the full screen goes back, I will upload photos of the problem & also some photos of the board etc. You might notice that I'm busy trying the tape method, I'm not sure exactly where the clock lines are so I'm just guessing & hoping for the best lol . I've already tried... -
5.5 year old 85 inch Sony Bravia X950G started showing gray horizontal lines across the bottom of the screen and the picture shifts slightly vertically when it happens. The lines sometimes get bigger/smaller vertically and bounce back. See the video for the problem. It seems to be happening after it warms up after an hour or so. Happens regardless of source. Right now there's nothing but power cable connected and it's happening. We did hook up a new Nintendo Switch to our HDMI switching receiver today, and played for a while with no issues, but this problem didn't occur til a few hours later while...

Hello,
i order a t-con because i had bad colors on my SONY KDL-40V3000 :
With the new t-con the color are good but there are vertical lines on all the screen :
I've tried the old t-con and it returned to the initial issue (bad colors but no vertical lines)
Is there a way to fix the vertical lines on the new t-con ?
Thank you for your help

I got this tv yesterday and it shows a screen full of colored vertical bars and horizontal lines that move, change, and dance around. When the set is powered on there is a slight buzz from the tcon. I removed one ribbon at a time and this was the result:
Right side connected, left side disconnected = half image on right (somewhat distorted, see photo attached) white screen on left. NO buzzing from TCON
Left side connected, right side disconnected = right side black, left side white with distorted horizontal lines near top of screen. Buzzing from TCON
I swapped...
