If it is the line fuse, have you checked to see if you still have AC coming out of the house recepticle?? Maybe you popped a house breaker.

If you shorted the line fuse to ground, you need to look at the foil side of the chassis and inspect for any blown foils. I looked on the sanyo website and they do not list your model but they do list a DS19330. I would also check the bridge rectifiers and the surge resistor (large white resistor) for damage.


Hope this helps

I check the bridge rectifiers and the surge resistor (large white resistor) for damage, and they are ok..

Install a Jumper wire or obtain a fiberglass brush here http://www.mcmelectronics.com and use the word "fiberglass" in the search engine. (first line Item)
If you obtain the fiberglass brush, clean the coating from the trace on both sides of the break and install a soldered in jumperwire of the appropriate size (dependant on the foil size).

Hope this helps.

Jesse
