If you can solder, try checking all the boards for poor solder connections. Resolder any that appear grainy or have rings. If that fails to resolve the problem, then we will have to start looking for failing capacitors in the power supply area.

Please note that there are potentially dangerous high voltages inside the set even when unplugged.

Keep us posted,

I have an RCA DLP tv model HP50LPW52. the sound was there with no picture. since it is 5 years old I replaced the lamp for the first time. got it all hooked up, turned it on and the tv slowly came on....


That is your Color Wheel that is bad. I wish you would have posted the problem before buying a lamp. I would have told you to treat yourself to a new set instead of putting good money into a DLP set that is 5 years old.

sqealing noise is a general syptom of a shorted horizontal output transistor and a bad flyback. it could be more but as a technician that the first thin i would check.

HIGHPITCHED WHINING SOUND AND COLOR FADES IN AND OUT


Well in case you didn't get an answer somewhere else the part making the noise is called the color wheel and has a motor that spins it at a high rpm. When they go bad they squeal real loud. You're looking at maybe $300-400 to fix parts and labor.

I have a 20" rca truflat tv with the fpl on and can't get the tv to turn on


Too general. Does in make any noises (like a click or high pitch squeal)? When you say "fpl on" is that a fromt panel light? Does it change color or flash?

Many "shutdown" or "dead" problems can be solved by unplugging the unit for an hour and plugging it back in causing a reset to the system.
