Default Re: Philips 70PUS7505/12 - Contrasts in image are echoed vertically upwards

I'm just preparing for the worst, I would prefer not to receive a replacement device that is a refurbished "equivalent model" with 50,000+ hours run time already.

I'll see what the service vendor comes up with, and I actually got a message today that sounds promising.
They let me know that the panel is the identified bad component and they have received message that it is available, so they will contact me later in the week to book a service visit to replace the entire panel.
It will be interesting to see how that works out.

That's good to hear, new panel should do the trick.

Today the repair guy arrived with a replacement panel.
He took one look at the symptoms on the screen and concluded that this fault is in the panel so it all had to go.

In fact, he brought an all new chassis with the PSU- and SSB-boards missing including the internal cable harness, so those were swapped over from the old chassis into the new.
He said that the TCON-board is actually part of the panel assembly, and that it was an LG panel.
The replacement panel was a newer version with a very different TCON-board.

The old TCON-board looked like this:


The new TCON-board looked like this:


This was the internal label on the old chassis:


This is the internal label on the new chassis:


Afterwards, the picture was stretched and doubled horizontally, so he entered the menu and went to set the new Panel ID 147 as was specified on the internal label.
But the range of values only went up to 24, so that was a bust.
The old value was 5.
He had to call someone to look it up, they asked if the TCON read "panda" or "chot", and since it was the latter, they said the correct value can be either 5 or 9, so he set it to 9 and that worked.

The old chassis would be sent back to the factory in Poland, he said.

The work report that I received by email afterwards, read:
Code:
IRIS Codes:
Condition: 1 - Constantly
Symptom:   34C - Clouding, “MURA”
Defect:    N - Defective electrical component / module
Repair:    A2 - Module replacement
So I don't know what exactly the cause of the error was, beside his comment that it was internal in the panel.

The TV works again anyway, so all is well.

I am glad that you never opened the tv. That could have nullified your warranty. Whew.
