I just plugged in my old hitachi big screen tv, (its a projector kind i believe) and within seconds it clicked off. if you unplug it for a while and plug it back in it clicks on for a split second then shuts off again... any ideas whats wrong?

how to unlock my Samsung TV TI-14ns

SORRY - it needs a new lamp. It is a protection for the projector so the bulb doesn't explode.

I purchase hitachi projectors with 3 year bulb warrenties now for our school as cheaper in long term
good luck

its really hard to tell without being there to see what its actrually doing, Im asumed is out of warranty and few things you can do yourself. go ahead since its projection tv is to open the back up and check the fuses and the lamp, make sure is unplug and use a good lighting so you can truly see clear of the circuits board. some boad will have its own fuses and check them all make sure they are good. pull the lamp out and check it. projector tv are not hard to work on since is big and easy access behind the TV. to test the lamp you can take it to the local tv shop and have it tested for nothing. If all the lamp and fuses check out fine to fix your problems I would not think it will cost more than 150-200 to fix it. hope that help some ..Good luck

I can't help you because after 26 months of ownership mine is doing the same thing (started on 7-12-09). Judging by the number of people with the same complaint I believe Hitachi knows that they have bad boards but refuses to replace them for customers unless they are within warranty. It also explains why the merchant that sold it to me in 2007 stopped offering Hitachi in 2008.

I'm disgusted because I'm anticipating a $300-$500 repair bill simply because Hitachi's design did not provide an external way of resetting it. Impossible to get to the menu to do a reset within 12 seconds before it starts the powering on booting cycle again.

Adding salt to the injury, mine is wall mounted and repair people will only work on it if it is readily accessilble when they walk in the door or if it is brought to the shop. Know what a 55" plasma TV weighs? Too much.

the audio amplifier inside the tv "blew up" after 8 years this is nothing unusual. my gut feeling is to hook up your surround sound for your audio. paying to fix this would cost $$$$

i believe your problem is heat the bulb is getting hot and the air or fan is not working properly so when it hits temp it automatically shuts off check your fan air flow filters etc

have the same problem

I have the same problem with a Hitachi CP-X345 Multimedia Projector. My Acer Aspire 3630 Laptop cannot be detected but it works without incident with a Dell Vostro 1500; just plug and play. Desktop settings to second screen doesn’t seem to help.

Yes,it's worth it ! Check for bad C702 capacitor next to HV
transformer covered partially by glue and E994 open pico fuse
in power supply .part # for cap 1-161-754-00 102K / 3KV.......T.
