help: rca 27" f26040wn with intermittent grey screen


Wet Willy

Jan 1, 1970
RCA F26040WN 27" TV manufactured May 1990

Sound and picture are okay and then cut out intermittently to a light
grey screen with white lines running about 1" apart slightly off the
horizontal with no sound.

Returns to normal after varying times with power on or off. If you
turn the TV on after turning it off there is a horizontal white line
on a black screen that pops open to the grey screen.

I googled the group and it appears to be a cold solder joint
someplace. Any suggestions?

I'm normally a hobbyist pinball reapair person. I have a temperature
controlled soldering station and was trained in military years ago for
soldering and basic troubleshooting. Mainly we did swap outs and then
scoped out the offending board.
