Hi there,

My Trinitron television (KV-19TS20) will work normally for fifteen
minutes before suddenly becoming saturated with audio and visual static
(no signal is discernible at all). After turning it off for a few
minutes, it will work normally again. Does anyone have any ideas as to
the cause?

thanks,

Sound like a possible failing RF amplifier transistor in tuner.

Max:
The problem you are describing is more than likely cracked, dry, cold or
otherwise faulty solder connections on the main board or in one of the tuner
or IF modules..... of course there are other faults that could be the
culprit too.....
......this is not usually an expensive repair at most shops....
......at the very least you should TAKE it to a service shop for a repair
cost estimate so you can make an intelligent repair decisions with facts
from a tech that has actually opened er up instead of internet or telephone
wild guesses.

Thanks, you guys. I was willing to get the TV repaired, but I
circumvented the problem by sending the signal through the RCA cables
rather than through the coaxial line.

Max
