When powered on, it functions normally for about ten minutes before the picture goes black, but continues with the program's audio. Changing source/powering the set off and back on again does not rectify the issue, black screen with sound continues. I uplugged the television from the power outlet overnight, plugged it in and powered it on the next day, when it again functioned correctly for 25 minutes before it again reverted to black screen with sound. Additionally, I can immediately power the tv off and back on again, and the picture will again come back for a minutes before again going to black screen with audio.
As the tv is out of warranty, Samsung was not willing to do anything nor would they admit to this being a known issue despite the multitude of people reporting/blogging about their same experiences. They say to call tv repair and provided me with contact info to their samsung authorized repair center.
I have done much reading and learned that faulty capacitors have proven to be the cause in many cases of other LCD Samsung televisions.
Although the capacitors appeared fine, we changed the the five commonly found to be the issue for others. Unfortunately, our problem remains, power the tv on, we get picture and sound for 10 - 20 minutes before the picture goes black and sound continues.
Called the samsung certified repair guy who thinks that if it was a power board issue, the tv would likely not come on with picture at all, he seemed to think it may be related to an inverter issue. He quoted the costs associated with the repair would amount to $240 labor (according to him was a $20 discount, since Samsung would pay him $260 for in warranty repair labor) plus the cost of the parts ($100 per inverter). I scheduled a pickup with him, which was to take place either Monday or Wednesday of last week, however, he 'no-showed' either day, nor called to advise/reschedule.
Can anyone offer any advice of which way I should go, not really interested in spending alot of $ to repair the tv which will still be substandard, when I can purchase a new, better quality tv for not much more. I can order an ip board for approx $120, but am reluctant to throw good money after bad if in fact the board is not the problem.
