ms3250 c321 32t800-7629 Shuttin Off

Posted by TTRON (My Page) on

Hi all. I know this is an old TV set but I think it is still usable if I can find the right fault!
My issue is this: the TV set picture will shut off quickly after turning it on.
After changing the channel it will come back on for a few seconds to a minute or so then shut off again.
The TV is still on but the Video and audio shuts off. I saw a post that said to test the 3340 resistor and it tests good so I checked all those R'ss right there in the CRT PCB but they were all reading a value. I do not have a schematic so I am wondering what to check next.
Thank you in advance for any help!

Hi, it's been a few days since you posted so I hope you check back to see this.

I'm not familiar with your set at all, but one thing I've found when working with electronics is capacitor failures. Older equipment - 70s and 80s - will have worn out caps, especially electrolytics in the power supply. Newer stuff is often made with cheap Asian caps that fail rapidly. A lot of flat screen TVs less than 10 yrs old have had cap failures that can be fixed very cheaply if you know what to look for.

Bulging top ends on capacitors are a telltale sign.
