Repairing a silent gong...

[EonPeon]

Hi All,

Well, as I was having the radiator replaced today, I had my mechanic pull the gong out for me at the same time.

So far, I have successfully dismantled the gong, and a quick test with the continuity tester and ohmmeter reveals the speaker itself is dead - no circuit.

It is a 5cm, 0.5w 80ohm. Yes, I though 80ohm was strange too, but there really isn't a '.' between the 8 and the 0...!

A round circuit board carries a single IC (an ELMOS ICR33271E), along with some passive components and a few surface-mounted components on the underside.

Since I do not have a 12v source, I am unable to test the circuit with a replacement speaker right now.

I intend to replace the speaker in the first instance, although who knows what else may have blown?! I figure its worth 99c to try! If I can get a replacement IC, I may change that out too, although my money's on (and hoping) that the speaker itself is the culprit.

When I'm done, I may post the results on here.

Wish me luck!!
