RCA TV won't power on

I'd like to ask some guidance on this one before going off to a repair shop, or forbid, having to buy a new TV. Out of the blue the other day, the power button on my late 1980s vintage RCA 27" didn't draw a reponse. After determining it wasn't a source problem, I pushed reset and it started up. Since then it won't power up and pushing reset doesn't help. This model - JKR985RR - is one of those 'race track' models, as one tech once called it, i.e., the kind built rock solid with a bigger transformer (and power supply?) to withstand use at places like race tracks and work forever. Is this likely the power supply or transformer that's gone bad? Thanks,

There are many things in the set that can fail, and cause it to not start. The set would have to be properly troubleshooted. Personaly, I would not put any money in to that model of set, especially considering its age.

Just as out of the blue the TV is powering up this morning. For how long, to be seen. Given the quality of this TV and the transition to HDTV that's about to occur in the US, if it were a simple repair, keeping this one in order for another two years or so is preferable to forking out $400 dollars or more for a quality new box to meet my basic purposes (TV, occasional VCR). Thanks.

If all else fails pull the power cord for a week and then try.

It has failed again and the plug's pulled. Voodoo, or is there something known to this? Thanks.

That apparently is a CTC131...reset switch??

Don't know. It is on the front panel behind the fold-down cover, unmarked. Assumed it was a reset. Never could find the SAMS on this TV years ago (vaguely recall them telling me there wasn't one).

check for bad connections near the mains input, and main switch continuity - wear and tear on the switch (and/or its soldering) may have taken their toll, if the set operates normally otherwise this seems likely....

Sounds like a cold solder joint to me. I have had that happened to my vintage

80's color TV.

As a followup, it definitely appears to a power (mains) switch connection problem. That switch (more like a lever that's pushed down) is now also acting as a volume up control and the adjacent volume up is playing power on/off more reliably. To get power, either have to be pushed quickly with force. I haven't opened up the back or cover yet and taken a look. Thanks.

It ain't the switches. Fix the MTT control module solder connections that are inside of it. The switches simply go to the computer control that is inside either the MSC or MTT control module. Follow the wires from the switches down to the correct module.
