Question about RCA P46921 46" Rear Projection Television
I have no picture or sound when I turn it on I here a sound in the back but nothing happens. This happened all at once. One day it worked and the next it don't.
This set may have a bad IHVT (flyback ) transformer. When this goes out it shorts out the horizontal output transistor. If the horz out tran is good, then check the hi voltage splitter. (Danger! there is 30,000 volts here!) Pull wire from splitter, insulate with a 6" length piece of rubber hose, and turn on set. If sound comes back the splitter is shorted. Hope this helps, Lee http://Todays-Info-Search.com http://CrazyComputers.com
