I have a Sanyo LCD Tv. If I turn the volume up to hear it across the room the Tv turns off and some times does not turn back on for a couple hours unplugged.

I have the same TV and I just replaced the Capacitors. It came with 2 10000UF 10V caps and I put in 2 1000UF 35Volt caps from radio shack. Its like brand new. There is even a video on how to change them on You Tube.

Its a common problem with many Samsung LCD TVs. We had the same problem on our Samsung TV. Based on some info on the net we called Samsung Support department ( 1-800-SAMSUNG). After describing the problem and mentioning that I have read on the net that its a common problem, representative asked for the model number and serial number of the TV ( I read them to her from a sticker on the side of TV). The Samsung Rep acknowledged that it was a common problem for my model and few other LCD models and they were fixing the problem without any charge to customer eve though TVwas out of warranty. She took the required info and gave me the ticket/transaction number and forwarded it to a local technician. Technician called next day and setup the appointment with us. Technician came within the 4 hr window that he had promised and changed the faulty capacitor on the power board and was done within 10 mins. Samsung rep had indicated that the technician will determine if the issue was with capacitor or not. If the issue was something else then tecnician will charge the regular service charge to fix the issue.

My mother's was doing the same thing (purchased 2008). Put up with it about 6 months and took it to a repair shop. Bottom line - the display panel has a flaw in and will cost more to replace than the tv cost. See about it now it yours is still under warranty.
