Carl,
May I please ask a question re my stock Omni 5? For some reason, it seems
to turn on--the lights are on, etc.--but the rig itself is making
absolutely no sound. It is really weird. I checked the switch on the rear
apron, making certain it is in the TRX position. But when I turned it back
on, the rig was exactly the same......no apparent noise at all.
What do you think we can check? I have gone through all five steps of the
Troubleshooting list, but no joy. The rig has not been abused, and there
is no sign of abuse inside or inside. Thanks in advance for any assistance
you may offer.
73,
Doc/K0EVZ
