Question about RCA P60921 60" Rear Projection Television
The power comes on but there is no picture. The sound comes on one side of the speaker , and the front panel controls do not work.
There are a few reasons that pic goes out on this set. First convergence problems, meaning amp need changing, but most of the time it gives you some kind of indication before it goes out, like color problem converg. not ligning up. Second it could be verticle output gone out. This is a 7 pin IC located at back of set on heat sink. Third the sound amp is going out. This could be an indicator but most of the time you don't have any sound. But still could be a problem

if your computer came with a motherboard disk the sound drivers could be on it
control panel sounds and audio,volume,advanced,speakers select appropriate speakers or audio you will find 3 drop down lists make the necessary adjustments there or
control panel,administrive tools,computer management,device manager,sound video and game controllers could be a yellow question mark? right click to re-install drivers
