Samsung UE49K6370

[An-klamm]

Hello!
I have a UE49K6370 where I suspect a defective TCON. Installed is a BN41-02481 and I have now found a seller on ebay who sells a BN41-02481A. Visually it seems to be identical.
Can anyone tell me if I can use that with the A?
If any more information is needed just ask.

You better look for these numbers so that it fits your panel, they may have different firmware and then there will be no image or it will be very distorted.

Do I understand you correctly: it is more important what is written on the stickers than what is written on the board itself?

Yes, such a board can be used with different panels, and on white stickers, just the number for your panel.

But you can transfer this spi flash (it contains the data and settings of your panel) from the original board to the new one.

Too bad, even with a new board the TV does not work.
I have no voltage for VSS, VON, HVADD and AVDD.
I tested the old board with disconnected and connected ribbon cables (to the panel). With the new/used one also first without connection and then with.
I measured the points all against GND with a multimeter in diode measurement.
VSS unending.
HVADD and AVDD at about 500mV and VON at about 400mV.
I think the values are ok.

Anyone else have a tip on what I should measure/check?
I got the measurement points from another forum post but somehow I can't find it anymore.
All other voltages of the measuring points (12V, 3.3V, 2.5V, 1.5V, 1.2V, 1.1V) are present.

By the way: backlight and sound is working.
Disconnecting one ribbon cable to panel does not change annything.

Without me doing anything, the TV suddenly worked again for 2 days.
And this morning I turned on the TV and after a few minutes the picture stopped and went black from the middle until it was off again.
I didn't pay attention to whether the sound was still on.
Turned the set off and on again and it's up since 30 Minutes
It sounds like a TCON board to me, but I said I had a new one in and it didn't help.
Anyone else have any ideas?
