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.
Try unplugging the TV's power cable from the wall outlet for a minute or two.
Then plug it back in. This will allow the capacitors inside to discharge and then recharge somewhat (you can hear that with the high pitched rising tone when you shut off and turn on this tv), and also 'reset' the power supply due to a power surge or static build-up.
I had the same problems you were having and tried a bunch of things, then finally power cycled the TV (as described above) with great success.
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.
Mine did/does the same,,,while in standby it also did/does produce a clicking sound intermitently.....now Pic and sound cycles on/off every 10 seconds or so. Intestingly...I could go on....but whats the point........JUNK
Hitachi says "to bad" 26 months old and $800 to fix. Buy another brand........
