I give up! Why would you need a schematic for a computer power supply? I've been in the computer business for over 30 years and have never needed a power supply schematic. Just curious!

We sell a repair kit for this board, which has the fuse, resistor and the IC that usually fails along with them.

You can find it at http://www.coppelltvrepair.com .

I've seen that board fail in at least three different ways, though, and this is the least bothersome of them.

We offer a repair service and have about 90% success even with burned boards. You don't pay any service fees if we can't fix the board.

Finally, when available we also sell boards ready for use with a trade-in option. That ends up a little more costly than a repair, though.

if you think that you are able to do that
