This model had some odd problems--answers to a few questions might suggest what is wrong

When set is on does brightness come up very slow or is somewhat darker when on?

that might indicate a lamp issue----set will detect if screen not bright enough etc.

With set on is picture normal? (no unusual color in back ground on screen or such? set is prone to light engine failures--the engine communicates with other parts of the set--something not right it shuts down.

My final thought is a power supply problem----this is not a easy set to get apart to service or look for things---for the most part the entire front screen has to be removed to gain access to the boards. Note the lack of many rear screws on the unit.

Amp turns off after about 5-10 minutes of use for a few seconds


One of two things...Amp is going into overload protection (should be indicated by a light on the amp), or you have insufficient power going to the amp....if this is the problem, try a 2 farad capacitor on the input power line to the amp.

I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.
