Re: Samsung LCD Power Board turning on and off.
found that the T0-220 MosFET QB802 has a loose joint, solder has cracked on one of the pins. Hope a resolder will do the trick. else i wouldnt know what part id need to replace it?Leave a comment:

Re: Samsung LCD Power Board turning on and off.
Hi, I'm new and I have the same issue. The TV is an LE26A457C1D and PSU is BN44-00214A Rev1.1- MK32P5B
Just wanted to document for anyone else having the same issue and hopefully add more evidence to OP's claim of the badly soldered MOSFET. I will check out and resolder the joints and report back.
