Altec Lansing 251

[gorr35]

I have a problem with my Altec Lansing 251 5.1 speakers. I get no audio from the right front speaker (The very speaker that controls all the others). Believe me i've tried all the settings including two different sound cards and get the same thing. It's definately a hardware issue. If I unplug them from the power outlet for a while and then plug them back in then sometime the right front comes back to life....but not for very long. But just turning them off for a while doesn't give the same result so it's not a heat issue. Just don't understand how the speaker that controls the others is the one not working. And yes the pins are good.

you have to reflow all the jack connection on the board. It's a common problem with these speakers. also check to see if the twin tower power caps (4700uF) aren't bulging or leaking
