Hello Paul,
I think this model number should have a switch near or underneath where you plug in the power cord. Push that switch in and press the power on button after that.

SOURCE: No power to my Hitachi 42hdm12

Hi, If even trying the TV in another known good outlet, it still doesn't work, do a hard/full reset - turned off via master power or unplug for a couple of hours. If all else fails, maybe you should seek the services of a qualified professional since this involves opening the unit, circuitry diagnosing and board/component repair/replacement. Hope this be of some help/idea.Post back how things are or should you need further information. Good luck and kind regards.

SOURCE: Hitachi 50UX14B rear projection: Took apart 2 clean, now red is off

What do you mean by covers? do you mean focual lens? did you replace them to there proper place (red to red, green to green, ect..). each has it's own focal legnth and must be placed on the correct gun. did you adjust (accidentaly) the red centering polls?if you did please have a tech readjust them you can end up with convergance amp overload. did you try to converge the lines? if they did not move when adjusting you may have a convergance amp problem. read my motto

SOURCE: Have a Hitachi 55hdt79...no pictures only sounds.

It might be the power supply, check the main power supply. Audio power supply is seperate to main power supply, thats why you have a sound.

Hitachi Plasma 55HDT79 volume gets louder

It's obviously beyond your expertise to repair it yourself. And it's not the sort of problem that can be diagnosed over the internet.
Find a trustworthy repair shop and take it there.

Hitachi 55HDT79 plasma television cycles on and off continuously. The blue led alternates between solid and blinking. The television seems to be in a continuous re-boot mode and does not stay on long...

i have a hitachi 55hdt79 that i purchased brand new some years ago and after only 1 year of use my girlfriend with her infinite wisdom threw something at me and as I dodged it the item hit and cracked the screen on the TV! I took it off the wall and boxed it up and has been sitting in my basement ever since. It still powers up and you can hear sound from it but for obvious reasons there is now image. If someone wants to make me an offer for it so they can use the parts to fix their own tv please let me know. email [email protected] it is located in Brooklyn NY 11223. you pay for shipping or I prefer you come pick it up. no reasonable offer refused.

55HT79 HITACHI BLUE POWER LIGHT BLINKS ON AND OFF.

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.
