Re: how to fix no picture on sony kdl40
Also i cant tell if your saying the backlight does not light up? or does it light up? (you should see if there is any glow from the screen in a completly dark room, while the set is on)Fixed so far 12 lcd's , 1 plasmas, 5 monitors, 0 dlp's (plan to keep the dlps at 0). and 3 atx power supplies, and 2 motherboards.Comment

I would suggest waiting for the t-con. If that does not fix it, then we can look at the main board or LCD panel.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

by CyberPhoenixHello, 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,...

by noisykid5.5 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...

by DKWS89Hey Guys,
So a few months ago my Sony XBR 49x900e TV screen stopped displaying the picture but the backlight comes on and I still get sound when I use the remote and navigate to certain apps. I haven't checked anything with the meter yet but started with ordering some replacement boards. I've tried replacing the BMKS board (used from ebay) and also completed the firmware upgrade based on Nicks TV repairs youtube video. I've also replaced the TCON (twice) and PIB.
All of these changes have resulted in the same issue with no picture. I've also tried disconnecting the ribbons... -
by ronniI have a Sony KD-43XE8005 with no picture on the TV when powered on. Audio and backlight work ok when powering on. Solid white indication light showing on front of tv bezel.
When removing the left hand ribbon cable from the T-con board, a white image is displayed on that half of the screen and a black screen is shown on the right. If I gently rub the ribbon cable on the right an image or purple black bars appear. The cable doesnt appear damaged, and if swapped with the other ribbon cable the same flickering symptoms can be seen.
