Re: Samsung 2253bw black screen

Please excuse me for writing in such an old thread but I'm having the same problem with my Samsung T220 as it uses the same power supply board.

I have replaced all the electrolytic capacitors and the problem remains.
I tried to resolder the joints on the two transformers and then it wouldn't turn on at all. I desoldered them and cleaned up the joints.
I measured the primary winding. It was 0.4 ohms for both of them. The secondary was 1.0kohm and 1.1kohm. I resoldered them with new solder and now the problem is back....
