how to fix my 9090DB?

[Marko]

Hi

The FM on this receiver doesn't stay on and working for very long. It can slowly, or rapidly fade into no apparent signal showing on the VU meter, no matter what I do. However, if I turn the power off, and let the thing sit for awhile, when I turn on the receiver, the FM shows up again. I have tried to turn on the receiver, but say just use the Aux, and later try the FM, which on the surface appears to be string and sound great. But, it will at some point fade, lose signal, and show as zip, on the VU meters. At that point, nothing I do short of shutting it down for a rest will do anything for the FM. All the other functions work really fine. I suppose I need to find a local(Portland Oregon) professional who is able to truly do the right thing for this neat 9090db.

Any advice y'all can send my way? I have heard rumor that the DB version of the 9090 has problems in this area....true or false?

Anyways....I have a backup receiver up and running sorta so-so.....any recommendations/help greatly appreciated.

Thx

Sounds like it may be a heat problem. Try having the cover off with a fan blowing on it and see what it does. Or to get more exact, use even the canned cb coolant stuff to keep just a smaller area cool. If keeping it cool lets the fm work OK, then try localized heat to try and narrow the problem item down. Good Luck.
