Question about Hitachi 60V500 60" Rear Projection HDTV-Ready Television
My Hitachi turns on for approx 2 min. it then shuts itself off, and then back on automatically only to shut off again after 2 min. the lamp was just replaced about a month ago. I'm assuming its a power supply issue.
Not an expert, but; 2 minutes is roughly the time it takes for something to go over temp.
So id be looking for an unplugged fan connector or similar issue. Its an odd problem where I suspect the bulb or sensor for the unit is reaching an over temperature situation as its unusual to start perform as expected then shut down. A sensor may have been damaged for one the improper bulb has been used. The tolerances for these devices are very fine, they normally shut down to prevent further damage like a baked lcd matrix etc.
If you are game to pull it apart or even to check it, then check for fan start at the time when it powers off, if it doesnt then thats a reasonble logical step for it powering off. So remove cover and check for fan being plugged in. Next step look around the bulb area for a small resistor shaped item that could be the temp sensor bent outta shape. Best of luck. :o)

I had a similar problem with my 42 in Philips LCD HDTV.
Here was the problem.
My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of
course) and found four bulged capacitors.
Many electronics companies were sold capacitors that failed in 2-5 years
instead of 10-20. The capacitors fail
prematurely due to a lack of preservatives. Unfortunately, they were installed in all
sorts of devices and cause a wide range of failure problems.
Here are some options for you.
1. Have it fixed by a professional
2. Open your TV and find PSB. Check
for faulty caps. If you find some (bulged
or leaking) bad caps replace the entire board.
3. Remove and then replace individual faulty caps. This takes some soldering skill.
Caps are inexpensive and if you can take care of it yourself
it will save you hundreds.
I have a tip/tutorial
on this site that may also help. It
gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's
called: Fixing the Philips Turns/shuts off on its own problem.
Hope this helps and Good luck.
