T.v. will not come back on.

My t.v. was working fine, and all of a sudden it turned off. We unplugged it for 3 hours and then it came back on, but 20 minutes later it shut back off. Now it will not turn back on at all.

Unplug it from the wall for about 5 minutes.
with it unplugged, Press and hold the power button for around 30 seconds.

RCA Colortrak plus. Model# F32672SB Serial # 807560570 Chassis # CTC187CJ3 Manufacture Date Feb 1998 Service # F32672SBFM3 4/21/08- TV worked fine last night. This morning worked for about an hour. ...


It's probably a cracked solder joint in the power supply / horizonal drive stages. As the unit heats up the joint is seperating and breaking connection. It could also be a component failing when it gets hot. Usually the voltage regulator or Horizonal Output Transistor (both mount to heat sinks).

If you know how to solder and want to tinker, unplug the set for a couple days (to let the power capacitors discharge) and resolder and crystalized it cracked joints on the board(s) where the power stages, and flyback transformer are located.

If you decide to operate the set with the back off, please be careful. The high voltage on a TV can be 30,000+ volts.

Hope that helps,

TV turns off after aboiut 2 hours of uninterrupted play


There is a software patch availabe to increase the thermal cut off temperature. Can only be programmed using the Loewe Cablemax kit. Another solution is that the fans at the back all blow into the tv, reverse one of these fans, this gives a flow through the cavity. Remember to remove the filter from the one you reverse.
