Re: tv no sound no pictures power light blinking

There are a couple of things you could check on this one if you have the equipment and are somewhat skilled in electronics.
Take a test meter if you have one, if not try the local radio shack. Unplug the set and remove the back. Locate F802 a small pico fuse in the SMPS 4a/125v. Test this for open - if open replace it...
Next locate Q472 ( 2SC1740 ) a common NPN amp transistor which will cross to NTE85 in a pinch. This transistor is in the shutdown circuit and if it's failed usually causes the conditions you have there..
Try at least these, and if anything here sounds the slightest complicated take it to a shop - it should be a rather inexpensive repair...

My tv has no sound or picture. It started last night, I went to turn it on and the red power light just blinked at me and nothing came on. I tried it again this morning and the same thing.

Lots of tvs after some years develop power supply problems, of this type, it may be capacitors drying out in the power supply, they usually swell up and deform a little. Cheap components but not a five mins fix.
not for a novice

No picture, sound ok

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.

If the standby light is blinking 5 times then repeating, it is likely a problem in your picture tube or related circuitry. Other possibilities include the "Jungle" IC which takes care of the video, chroma and deflection processes and is a bear to replace. Either way, it could be an expensive repair.
