I have an Audiovox *flat panel in the shop for repair. There is an

may be the extent of the problem on this model. Of course it could
also be the tip of the iceberg for sure. I won't know until I replace
it. The problem is I have no chemical fuses, only glass. Can it do any
harm to replace the 7.0 amp chemical fuse with a 7.0 amp AGC type?

* Chemical fuses like the 'Belfuse' series are coated with a chemical

fast blow and a special class of fuse. *I wouldn't recommend using a
standard fuse, since you can cause major damage in the equipment before

a linear supply, can you substitute a variable voltage, and current
limited power supply for testing?

You can't fix stupid. You can't even put a Band-Aid™ on it, because it's
Teflon coated.

Its a SMPS with several different outputs. There is a feed back
circuit I believe that would make it risky to try to sub in a supply.
Thank you Michael for the information you provided. Sorry Phil that I
blew right past your response however I guess I'd have to wonder if
YOU read what I wrote. I thought that I was clearly asking about a
Chemical or "pico" type fuse, not a polyswitch. Lenny
