Panasonic 32" TV

[mkwilk]

I have a 5 year old panasonic tv that turns itself off and back on after it warms up. Shuts off about every 20 minutes and remains off for about 2 minutes. Will continue to do this all day. I removed the back and cleaned out all the dust. Any tips on how to troubleshoot/isolate the problem?

Most likely a bad solder connection.Use a lighted magnifying glass and look for connections with hairline cracks.Most are located in the transformer area but could be in the power supply as well.Post the model # and I'll look up the location where most have been reported.
