I have the same problem. No picture, but great sound. I pulled the front cover to expose the picture tubes, and when it is turned on, you can hear the tubes energize but nothing comes on. Is it the power supply? If so, is it easy to replace on my own?I have the same problem. No picture, but great sound.

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!
Rca has been known to have bad solder joints in the deflection circuits. Usually around the flyback and transformers.. check it over real good. Just be careful as you can still get shocked after the powers removed the capacitors and picture tube will hold a charge in them.
Sounds like horizonal output transistor could be over heating. There could be other problems. But I would start there. You can find the part number on the schematic inside the set. If you change it yourself don't forget to use the included insulater. Part should cost between 15 & 20 dollars. You will need make & model # of set at electronic parts store.
Diagrahm inside set will show you location of transistor.
