Question about RCA P46921 46" Rear Projection Television
My projection tv will not turn on & makes a beeping noise (similiar to a watch alarm) in the rear. What can it be?
Shorted horizontial output transistor q14401 -I think- and bad flyback transformer(high voltage transformer).The noise is the power supply starting and shutting down very quickly because of the shorted transistor.Very common problem,but some of the flybacks are no longer available from RCA.Sometimes you can use generic but questionable life on some of these.
