A power surge killed my tv, computer and Xbox 360. Turned out to be the power supply box on the computer, and the power brick on the Xbox 360. I opened up the tv, and saw the fuse was blown. I didn't notice any other burnt spots on the circut board. I replaced the fuse, but as soon as I plugged the tv back in, it blew again. I have no clue what to do next. If someone could help me out (in a tv repair for dummies sort of way, since I have NO clue what I'm looking at back there, other than the fuse) I would greatly apreciate it. This was my kids tv, and as fond as I am of Handy Manny, I'd love to be able to watch grown up shows once in awhile! Thanks in advance!

For this you will need a multimeter that can measure resistance. Check Diodes D501~D504 and or Diodes D527,D529,D530 and D531. These are the bridge rectifiers and the ones that fail during a power surge that will cause the fuse to blow instantly.

Location is: Looking in from the back, Power cord input, Fuse, Square xfrmr/coil, left to diodes (away from right edge of circuit board).

Hope this helps
