The tv will come on and play for a few minutes, then the picture drops
out, (screen turns black and sound goes off) then it will come back on, picture and sound at the same time. It will repeat this process over and over....help!
Josh is correct. I had this problem and ordered a new replacement XL2200 lamp from Sony and that fixed it. By the way, the ;amp installs from the front so there's no need to pull your TV out from the wall. Look at you manual, it is accurate in this respect.

Bob, take a flash light and point shine it at the screen while you have the tv on. If you see the image, you need a new backlight inverter in your set. Try out ShopJimmy.com for parts if you end up needing that. Hope that helps!! TeeVeeMan2@gmail.com www.shopjimmy.com
Ur tv now power on only have picture few mins,than dead,have sound only?Yes,than the 1 or 2 the long board call the LCD inverter boards are dead.The LCD inverter long boards help the LCD screen to have a backlight to produced a picture.Tries websites like Shopjimmy.com,Ebay.com to buy 1 or 2 long LCD inverter boards for the replacement.
Could be the signal board has a bad cap, in this case it sounds like you are getting intermitten power to the inverters....when the tv goes down and of course you have audio....Shine a flashlight on to screen and see if you have a picture...look carefully. If this is the case..you have the above problem!
It sounds like you are saying the "video looks scrambled but the audio keeps playing OK"
Normally this is a Video Processor Problem that requires a Board to be replaced.
When the problem happens, can you see the TV menu or the TV's On Screen Display clearly.
I suggest checking to see if the problem happens with the video inputs like, Composite(yellow/red/black), component(RGB/yellow and black), HDMI and S-video. If it happens to all inputs then you need to replace a board.
I have a sansui 19" LCD TV+DVD I had to attempt multiple times turning the TV on to get a picture. The sound was fine. This kept happening when I would go to turn on the set the TV kept playing fine with picture & sound but after the 2nd attemts I turned it off & then tried to turn it back on which took multiple attempts, it kept playing for a few minutes then the picture went out but the sound was still there. The set is not yet 2 years old.
