You probably have a bad IPM on the Y-sustain, it's repairable but a lot of work.

Picked up a bahemoth plasma TV not too long ago and just now getting around to looking at it.
No picture but you hear the TV static (white noise) playing loud and clear.
The back was already taken off (and no screws were provided) as the previous owner had already taken a look.
But it seems they didn't get too far and just left it.
When I first took a look I was amazed at how pristine the inside looked.
Its as if the TV had been in a time capsule.
Caps looked like they were just pulled off the self.
Copper coils had no sign of corrosion on... -
Do you know where I can find a firmware upgrade for the Hitachi 42HDT79 plasma TV? My set currently has firmware V0112.0001.
Their service website seems to be on SalesForce now, which requires a login.

Hey guys, I recently acquired a Hitachi 55HDX99 plasma TV that doesn't work. The TV powers on and eventually goes into standby which is indicated by the blue power led changing to orange. If I plug a VCR into it to keep it awake, I can feed an audio source in and it will play the sound no problem. The volume controls on the TV work as well so it is obviously just a display problem.
I found the Hitachi service manual online which is also hosted on tom66's manual archive. Compared to the Panasonic service manual I had for the last plasma I worked on, this one is underwhelming to say... -
Hi all. Up until 3 years ago I used component video as the connection between my Comcast cable box and this TV and never had any issues with it -- it always worked perfectly. Then I upgraded my cable service and the new box had only an HDMI connection. The Comcast remote controls both the cable box and the TV. About 50% of the time, when I would first turn the TV on I would get video but no sound. After trying new cables, a new cable box, and switching between the two HDMI ports had made no difference, I changed the video source to see if that made any difference. It did not but I did notice that... -
Hey guys, recently I repaired a Hitachi 55HDX99 Plasma TV with help from you guys on this thread. https://www.badcaps.net/forum/showthread.php?t=75627
The problem ended up being a shorted buffer IC on the upper buffer board.
After the repair, the TV was working fine and we used it on and off for about 20hrs. However, the last time we were using it, the TV just turned off in the middle of watching a show. There was no power at all and the power button did nothing.
Unplugging the TV and plugging it back in makes all the relays click and the power light starts...
