Question about Hitachi 46UX24B/25K 46" Rear Projection Television
When power suddenly goes off,I use remote to power on producing this result: I hear the familiar "shutting OFF" sound ,I press power button on the remote a second time and the power comes on as usual. I am OK for sometimes an hour,sometimes only 5 minutes. The overall picture is always great. This set is 10 years old. I am 70 and can't afford another new TV at today's prices. Would it do any good to unplug it,take the back off and vacuum out the dust? This is NOT a worn power cord problem ; it has not been moved for 10 years.

When cold, the TV comes on normally. After it warms up it shuts itself off. It first did this about 1 week ago, and wouldn't come back on at all. I unplugged her and she came back on and after about 3 minutes the screend blinked once or twice, but stayed on. This weekend she started shutting of again with a vengence. Every 2 or 3 minutes and unplugging doesn't make a difference. On and then off. I read the other post suggesting a voltage regulator, but I am reluctant to start buying and hanging parts without some other confirmation. Is that a common fault / repair? Are the others AS common or is the VR in a 12 year old set a likely candidate.
Intermittently turns itself off. Can be turned back on after a few seconds, but may shut off again at any time.
tv stays off after power outage sometimes for days
