I have a Viewsonic VPW425, that stopped working after an electrical storm in the area. I assume something got hit and damaged the TV.
Currently I canno got it to display any picture other than the on screen menus and etc.
If I hook cable to the tuner, it displays that it detects and finds the channels, but when I tune to them no sound or picture.
I have tried the RCA jacks with the same results.
I have not yet tried the DVI or RGB, but assume the same issues.
Any ideas on how to repair?
Seem like the power supply hav blow off inside the unit.

The TV Does power on, and I do see the menus though. In fact I can tell it to scan for channels on the CABLE TV Tuner and it even finds the channels, but when i turn to them, nothing is displayed, except the built in screen saver and onscreen menu.
Do you still think it is the fuse?
I did take the back off and look for blow components or burned boards, etc. did not find any. nor did I find any blown fuses. I tested ALL the fuses I found with an Ohm meter just to make sure.
may have been one i missed though, if you still think this is the issue, I will take it back apart and see.
