I have a Hitachi 55vf820 which I purchased 2 years ago. It was a good purchase until recently the television started to turn itself off automatically about every 15 to 25 minutes with no ryhme or reason. The lights on the front of the set for the power(blue), Temp Indicator(red) and Lamp indicator(red) in that order start blinking. The set then powers off for about 20 - 30 seconds and then turns itself back on again.
Please help...
I would suggest that you guys turn the unit off when this happens, unplug the unit for 30 seconds, plug it back in, and see if this helps. If this does not solve your problem, you should call 1-800-448-2244, so a service center in your local area can be found for further assistance.
The most common problems I have found in this model is solder joints going out in the vertical and on the driver transformer.
I would say the picture tubes are probably starting to go out by now and the technology is changing.
Look at the new sets. LCD and DLP are using LEDs.
Manufactures are beginning to equip their sets with ATSC tuners that bring in High Def. stations by using a pair of rabbit ears.
In a little over a year most signals must be High Definition and the government is supposed to send out checks for about 40.00 to help fray the costs of converter boxes to convert the older set.
So, my thoughts are, the set is about 17 years old. The cost of repari and the repair itself would be like putting a bandaid on it.
Capacitors by now are beginning to dry out and solder joints are starting to open up, not to mention that the picture tubes are getting weak and changing luminance and fading..
Most sets I repair at this age have future repairs.
Check out the new technology.

I am having the exact same issues. My 55vf820 will stay on for about an hour and then it shuts down for 20-30 seconds and then turns back on.
I have this same problem. Temp,Light, and power light on my 55vf820 starts blinking together and tv shuts off for a few seconds(cooling down i am guessin) then starts back up. Is a bulb replacement going to fix this problem?
Temp,Light and Power LEDs blink simentaneously and tv shuts off(cooling off i presume) then comes back on in a few seconds. The forums i have read suggest lamp replacement, but would like a confirmation before i invest $200 or more.
