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.
