I have a pair of EVENT 20/20bas monitors.

They've worked great for my purposes for years.

One of them still works perfect.

The other works for a few hours, then...

I hear a POP! And the LED slowly fades out...

I turn it's power switch off.

If i wait a while (10-30 minutes), i can turn it back on and run it for a few more hours.

They sound identical.

I have above average soldering/desoldering skills... but am not an electronic engineer.

If i know what to replace, i can do it.

Can any one give me some idea of what this problem might be caused by?

Thanks
