ch1d3th Posted June 19, 2008 Share Posted June 19, 2008 Equipment: Promedia 5.1 THX/BASH w/ 500 W sub An electrical storm hit the area and blew a circuit breaker in my apartment. The rest of my electronics survived, including 3 desktop computers, a television, and gaming consoles, but the Klipsch's, which were connected to a surge protector, would not power on. Thinking I would have to replace a fuse, I opened up the sub. The fuse seems to be intact, but there is a blue tab-like electronic part nearby that is fried. I uploaded a picture here. If there is any other information I can provide please ask. My question is, how do I get a replacement for this part? Failing the protection of the circuit breaker and surge protector, shouldn't the fuse have protected the sub? Does anyone have a method of protecting their system from a similar fate?

Marvel Posted June 19, 2008 Share Posted June 19, 2008 You would probably get a better answer in the Promedia section, but that blue part looks like an MOV (Metal Oxide Varistor), which is what is in surge protection devices.The give their lives to protect your equipment. If you are handy, you could change it yourself, or call Klipsch and send it in to them to repair. If it did its job successfully, the fuse and MOV would be all that needs replacing.

ch1d3th Posted June 19, 2008 Author Share Posted June 19, 2008 Thanks for the info. I would like to attempt to solder the part in myself. What MOV would be compatible with the sub? And where can I get one? As far as I can tell, the fuse itself is fine. Quote Link to comment Share on other sites More sharing options...

JackDalton Posted June 19, 2008 Share Posted June 19, 2008 Unfortunately, the lightning strike exceeded the MOV's ability to protect your sub. Have you plugged it into anything besides the original surge protector? It's a longshot, but perhaps you're not getting power through the surge protector. But more likely, because the fuse is intact I'd bet something besides the MOV has failed in the sub. Sorry about that. Thankfully the rest of your gear survived. You may want to open up your surge protector and inspect the MOV's in there. Good luck, Art Quote Link to comment Share on other sites More sharing options...
Daddy Dee Posted June 20, 2008 Share Posted June 20, 2008 It does seem odd that the fuse would remain intact when there was enough power to fry that board. Hope you can get this little rascal going again. That is most fortunate that the lightning did not take out your laptops. Quote Link to comment Share on other sites More sharing options...
