Weird Mitsu DLP problem

[electronjohn]

I have a Mitsubishi WD52525 DLP set that's developed a couple of weird problems.

Problem #1: Periodically functions such as volume, etc. will "freeze"..IE you'll be unable to change the volume from about 25-30%. Can't change sources, etc. either. Don't think it's the remote...since the volume adjust on the front panel won't work when this happens, either. Only way to solve it is to get out the bent paperclip & do a reset.

Problem #2: The set will just shut down. Doing a reset will allow you to turn the set on again.

There seems to be no rhyme or reason to these events...and they seem to be happening more often.

My first thought is a weakening cap somewhere inside...power supply? I'm not very excited about disassembling this beast...but that may be the only solution. I plan on running the situation past Mitsu customer service when I get a chance to see if they have any ideas.
