Probably time to check all the electrolytic capacitors in the set including
the power supplies. While in there then you can also check for poor solder
connections.

Hi,
I have a 13 yr old Sony KXP46EX25 46" rear projection TV. In the last
week, every couple hours, the power clicks off for approx 4 minutes and
then comes back on. Other posts have suggested that the power supply
might
have a cold solder joint and loses power for a few minutes, cools off, and
then powers on again. Does this sound familiar to anyone else?? Any
suggestions to diagnose/fix the problem?
Thanks!
