There is a sub-board in this set that powers the convergence circuit. Often a big Ic shorts, two diodes and finally the main fuse. not something you can fix yourself.

1. Check menu to make sure a signal is present. try video 1 with a external video source such as a VCR. If this produces a picture check for tuner signal by hooking the VCR to the antenna and tuning to channel 3 or 4. If their is no picture check antenna connector on back of set for looseness. If loose resolder antenna connector in tuner. If all these test fail the tuner may be defective and will require replacement.

If you will look I bet you'll find a switch on the back of the TV for internal or external speaker. It's probably gotten switched to EXT. somehow.

tv worked great, turned it off one day and back on the next and the on light would not come on nor would the tv work, rear projection 52 inch rca

TV worked FINE for the past 2 yrs---this morning we woke up and the screen is totally BLACK! No sound..nothing. REmote doesn't do anything to the TV. Red light says ON unless we unplug it. Remote won't turn off the TV.
Any advise? Picture tube??
Worked great w/out any problems until we woke up today!

Thanks,
Tina

is it beeping or cherping ,cherping it the power supply trying to run.power supply poss.faulty

replace the keyboard or remove the switches for channel up/down to see which one is bad. if neither does it, there are some components around the microprocessor that can cause this.
