power surge blew fuse in stereo
Hi, a power surge blew a fuse (2A/250V) in my shelf stereo system (JVC
MX-J10). I replaced it, but as soon as I plug in power, it blows out immediately. Any ideas what could be causing this? Thanks in advance! |

there's nothing you can do that won't make it worse and more costly to have
repaired. LOL! Is this a typo or are you saying if he does anything it will make it more expensive to repair. Thats proably true, but funny.

Obviously one or more components are shorted, it shouldn't be too hard for an experienced tech to fix but if you have some experience troubleshooting electronics, a multimeter and soldering equipment, there's nothing you can do that won't make it worse and more costly to have repaired. |

Thats proably true, but funny. Yes, if he does anything while not knowing what he's doing, it's very likely to do nothing but damage it further. I've seen it more times than I can count. |

I thought it was funny because you said if he had expirence troubleshooting
he could only make it worse. "James Sweet" wrote in message news:_Skch.87$QD3.68@trndny01...

The most common cause is a failure in the output stage. The failure is
usually the power output devices, their respective drivers, and sometimes their support components. -- JANA _____ wrote in message oups.com...

Any ideas what could be causing this? Thanks in advance! Is this the line power input fuse ? In what way does it blow - with a soft blue flash or violently with a bright white flash and total vapourisation of the fuse wire ( inside of glass blackened ) ? Are you replacing with the correct fuse type - almost certainly " T " rated ? I see many HiFi's with a blown fuse after some kind of power surge - often due to power interuptions when there's storms about, and I actually find it quite rare on modern equipment for there to be any issue other than the fuse. That's not to say, of course, that surges are nothing to do with your problem, and it has plain and simple just gone wrong. Arfa |
