    It stay's on for about five minutes or so before it shuts back off. It can go on like that until I get tired of it.

Shuting down with the red temperature light blinking means it is overheated and needs to cool down a bit.

Make sure if your model has aircooling fans that they are clean and the air goes throught easyly.

The protection circuit is shutting the set down. The reason it comes back on in 15 minutes or so is because the protection circuit resets itself after a while but detects the same fault when it is ON for a few seconds.

It is the protection circuit that is causing the set to shut down. Unfortuately we don't know which of the many sections of the tv is the one causing the problem in the first place.

Can you tell me how long it stays on and how long does it take before it comes on again?

Well..the control board has this sort of issue. sometimes, if you turn if off long enough to reset itself, this may clear..otherwise, it's a replacement of a non inexpensive component..

what's your technical ability like?

Your lamp door switch or lamp switch (there are 2) may not be fully engaged or one may have failed. Try seating the lamp again, you may not have it fully installed.

Hitachi 50VF820 (LCD projection)randomly turns off, all three lights (temp,lamp,power)blink then the set turns back on after approx. 30-45 seconds. Lamp was changed approx. 4-5 months ago. Cleaned out all...


I believe I may have solved this problem by putting a small fan blowing on the intake of the Lamp fan. I put the fan in place and the TV has not turned off randomly since. That was only a day ago so I'll see if it is a permanent fix. If so I will probably try to mount the fan on the back of the TV out of sight.

TV shuts off


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.

My 60" lcd projection tv wont turn on sometimes and throws a lamp light, and if i watch tv for a while and turn it off it wont turn back on and throws the red lamp light


The buzzing sound you most likely hear is the ballast trying to fire up the lamp. I would say replace the lamp and yes they can act up at will. If this is the first lamp replacement ever then you are doing good.
