SOURCE: my tv is hitachi 55pd plasma

Hitachi did in fact stand behind their product and resolved the problem. My hats off to them! Panel was replaced due to faulty ribbon cable supplying signal from one of the drivers. Unfortunately for my specific issue there wasno other solution as the ribbon cable in sealed inside the glass panel.

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.

Black vertical strip on Hitachi plasma

seems like a lose ground issue from the vertical scan board which usually causes this problem. A scan board repair or replacement should fix this intermittent problem.....take it too your local repair shop before this problems spreads and the tv totally shuts down....

Vertical black bar down the middle of hitachi plasma tv

Ok if your hitachi TV dies with no power anywhere try this:
Some models have a kill switch under the bottom edge. It's like a gray switch like a small light switch press it back in and voila let there be LIGHT. Saves you at least a $200 trip to repair shop!!

Screen went black while watching, no sound

Almost for certain your power supply board is bad, Can be repaired at the component level only if you have some electronics savy! Good Luck!

Black line in center of screen

These black lines on the plasma screens are very fixable.  There is a dry solder joint on a circuit board at the bottom of the plasma that needs resoldered.  There are 6 or 7 "ribbons" along the bottom of the screen that correspond to vertical sections of the display, so you just follow the black vertical line down to figure out which one is faulty.  I just performed this fix successfully on my first attempt on a Gateway plasma, but it will work on most plasma's, specifically Hitachi, gateway, LG, Hyundai, & Akai. I think they may all have LG boards, my gateway did.
I can't really describe very well what to do, but I assure you it is fixable.  If anyone is near nashville, I might be able to help you out.  My email is [email protected]
thanks,
ST
