Re: Samsung BN44-00506A power board dead no standby

Just to clarify I spoke for NT801S not NT8001S
My mistake.
Could you give me a clue which part to use for replacement.

EDIT: I found it: SCK-053

OK. Thanks.
I resolder the rectifier, transformers and other suspicion joints.
What about NT8001S. I think it has a crack and prefer to change it.
It gives me 25k at 20 oC. Is that correct?

hello,
I do not want to start new thread and I will continue writhing in this because I have a problem with BN44-00506A too.

The T27B551 is starting and working well for about 30-60 minutes and after that it is starting to restart in cycle. I can see the samsung logo while restarting and that's all.

I opened the TV and sow that under the NT801S there is a burned mark.
I would like to replace NT8001S but not sure with what exactly. Please help.
