Question about Standard (CRT) Televisions
TV powers off after an hour or 2. Took advice yesterday and took off the back, check all wired connections and all seem OK. Tapped in the circuit board but could not get the TV to shut off to isolate the problem area. HOWEVER< the second i moved the circuit board, the TV powered off...cannot find any dark areas anywhere on the board. with the back off, I can unhook it for about 5 minutes, plug it back up and it comes right back on for an hour or so....any suggestions?
If the second you moved the board it powered off would really make it sound like a cold solder joint or loose solder connection
they are hard to find, take the board and tip it so you can see it and
move a plastic handle of screw driver over the solder joints while the set is UNPLUGGED and look for and old discolored solder joints and any hair line cracks you can even flex the board to see if you can find it... look very close it will be hard to spot.
