Samsung LN-S2651D Schematics needed

[n1iwv]

Hi All:

I am looking for schematics for a Samsung LN-S2651D / Chassis GBD26KU.
Specifically looking for schematics for the power board BN96-03060A and the main boards BN94-00863A. The sticker on the main board also shows number BN41-00679C.

Any help would be greatly appreciated.
Thanks in advance

Hi Budm:

Thanks for the quick reply.

That was the first place I looked.
I've been using the "main board" schematic for the LN-S3292D that I downloaded from that site and it looks very similar (if not identical) to the main board for the LN-S2651D,
But I didn't see anything for the power supply / BN96-03060A.

Do you have a BN44 number on your power supply? Or just BN9x?

Hi Tom66:

I've looked all over the power supply board and the only number I see is
BN96-03060A.
See attached picture.

Thanks for your reply.

OK, what is the TV not doing? No indicator light at all? Voltage readings on the connector of the power supply board?

When the TV is plugged into AC, the red power light blinks 4 times and the light will extinguish.
After 30 - 40 seconds that cycle will repeat ...endlessly.
Pressing the power button does nothing. No video, sound or back light.
It appears that the TV never enters into standby mode.
I have the service manual, but it provides no schematics.
Initially I thought it might be the main board, but I measure the voltage on pin 1 on CNM801. It should be 12 volts, but I measured 13.8 volts.
Now I suspect the power supply board may be the problem.
See "wire diagram" attached.

Thanks

Just a quick follow up on this repair.
It ended up being the main board.
Replaced it and the set is working fine now.
