Re: hitachi 50 plasma p50t501
I'm not sure if this helpful. I know these TVs have lots of Y-Sus and buffer issues from previous experience with this model: https://cdn.badcaps-static.com/pdfs/...decbc0bfe1.pdfComment

Hi,
anyone able to provide the service manual for old plasma Panasonic TX-P42ST50E?
It turns off almost immediately (0~5 seconds after pressing the on/off button) and starts flashing the red diode 6 times.
I disconnected the left-hand side board (SC?, both the ribbon cable and the power cable to it) and also another ribbon going to bottom left board. Then the led signal is 8 flashes. According to service guide to another Panasonic plasma it would mean the left-hand side board is faulty. But I'm not sure it 100% applies to my model.
I checked that board for any obvious faults... -
Hello,
Stopped by this site trying to fix my parents Panasonic Plasma TV.
Model number is TH-50PZ85U

Section 6 in the service manual talks about power and no screen,...10-30-2024, 10:09 AM -
Hello,
My Oct 2012 panny plasma quit working yesterday.
It was on when it happened. It let out a bit of burned plastic/circuit board smell. I was not able to find any burned parts though.
Now it produces 8 blinks. According to the repair manual, that points to SS/SS2 board(s).
I completed the steps in the guide: unplugged SS33, the TV turned on with a black screen, no blinking codes. Then I checked the continuity between pins 1 and 2 of the connectors SS52, SS54-SS57. The continuity is ok in all of them. Guide suggests to replace SS/SS2 boards so I placed an order... -
Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

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.
