About a week ago, the picture on my 36'' Magnavox TS3270B101 started going in and out. The screen turns black and stays that way for about 20 minutes or more. Then the picture comes in fine just long enough for me to get interested in the show I'm watching and then it goes out again. The sound is never interrupted.
I'm not sure if this has anything to do with it but when there is a bright (or white) spot on the picture, it smears greenish-white to the right. This has been happening for quite a while though.

checked the vedeo section of the main PCB of the unit, maybe some defective parts, try to look the back of the picture tube if theres a light, if none, cheke also the horizontal section, especially the flyback transformer
Same problem with mine. Relays click, sound, no picture and a flashing power LED. I finally found a schematic online. I went through the high voltage circuits and found the power transistor 2SC5570 was shorted out. There is also a pico fuse in that area but my was not open. I replaced the transistor and prayed the flyback transformer was not shorted. It wasn't, I'm watching my old 36" right now. Not a bad fix (17.00) bucks. Wonder what a service tech would have charged ;)
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.
A few weeks ago my set started flashing to a black screen. Now a couple of weeks later, i have no picture, but the set turns on and i have sound. The standby light is flashing. I purchased the set in 2000 so it is seven years old. This is the first problem. Could it be all three of the bulbs?
Could it be all three of the bulbs?
as you say that sound is ok that means your power supply &high voltage section is ok.
please check chroma ic luminance section or system control section stand by ckt
This set is very popular for the capacitors to dry upa and go bad in the main SMPS as well as the switching power supply. If you have no know how on how to test capacitors or solid state electronics please take the set into a repair shop for an estimate
