Video takes i hour to clear-up

The board that call the T-CON board it is dying and dead soon.That why it is causing horizontal or vertical lines and distoted pictures.This T-CON board sit in at the bottom in the middle of the tv LCD screen panel and it only job are to decoded pictures pixels before it go onto the tv LCD screen panel.Tries websites Shopjimmmy.com,Ebay.com to buy a whole new refurbish T-CON board for the replacement.

you should check its its inverter board. it may need replacement though.
thanks for using fixya

Bad inverter?

That is correct. Sony has extended their warranty on panels for this model until Oct. 31st 2012. Just give Sony a call or simply take your set to an authorized service center and you will get your set fixed for free.

Does the picture just get dark or does the picture go out completely? Does it do this with both the cable and the DVD? Is the audio affected?

We also have vertical lines with our JVC 62"... turning it off and letting it cool down is the only solution. For us, we know it's a problem with heat. We simply are wits end on fixing it. added two additional fans, a exterior fan to blow heat away from the back of the tv, pulled everything else away, etc.... Anyway, goodluck.

Usually that symptom is caused by cracked solder joints on the vertical output IC. As the IC starts heating up, the picture starts breaking up at the top with several "dancing" dark lines appearing, the top scrunches down and then when the vertical quits altogether, the screen goes completely black. A good slap on the side of the TV might make it happen faster or clear it up temporarily. If you have experience working on PC boards then you can resolder the pins of the vertical output IC but if you have never soldered parts on PC boards then allow a qualified tech to handle it for you.

You didn't say if you are receiving an off air picture or cable or satellite. The reason the commercials look good is because the local station (or source) transmits them "in the clear", that is, without any enhancements to the video signal. Network programing or local newscasts are sent through a device which inserts a reference signal in what's called the "vertical interval". You may have seen this as a series of flashing dots or pulses at the very top of the picture. There's a lot of information packed into the VITS (Vertcal Interval Test Signal). One of the lines contains a reference pulse for video which is set at a certain level. Your TV sees that level and automatically adjusts its circuitry accordingly. What I suspect is that your set is out of calibration and is pushing down the video signal because it is not "seeing" the level properly. A video alignment should correct this and can be done by a good repair facility. Hope this helps.

You have whats known in the biz as a cold solder connection on the vertical output IC or on the associated components. Not a job for the handi-man unless you know the issues with safty, and precautions to take with Hi voltage inside of tv sets. Shouldnrt cost much for the local shop to find your problem . Now on rare occations the poor connections are inside the IC and the IC has to be replaced. Good Luck
