Question about Sony Grand WEGA KF50WE610 50" Rear Projection HDTV-Ready Television

TV Turns off and on

Our TV works for several hours and then turns itself off. A couple of minutes later, it turns itself back on again. Then it goes through the on/off process several times within a short timespan (a few minutes on, a few minutes off). We turn off the TV let it cool down. Turn it on and it is good for another several hours.

Could it be a fuse? If so, can we fix or do we have to call a repairman?

How long since the last time the bulb was replaced? It sounds like the bulb is overheating and triggering a safety shutdown.

It's probably in need of nothing more than a good cleaning (open it up, clean off the boards with a can of air) and *may* be time to replace the bulb.

    Rated "thanks for trying"???

    Look, this is a 2003 model known to have bulb problems. Sony indicates an "average" 1-year replacement for the bulb on normal usage.

    If you've had it for a couple years of normal usage without a bulb replacement, you've been lucky.

Power turn off after 45 minutes to 1 hour used

Check the "Sleep Timer" settings. If set to 45 minutes then TV would automatically turn itself off 45 minutes from being turned on. The variance in the "on" times is due to the TV turning itself off after not getting a signal from the remote for fifteen minutes.

Good luck,

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,
