Hi, Wonder if anyone has suggestions as to what may be wrong with my 940. It has suddenly refused to produce any sound from the speakers, other than the sub, which is working fine. I have checked the usual things such a sspeaker switch selection (tried all possitions). It's not muted. Checked and replugged all of the speaker connections. Run back through the setup and can't see any thing obviously amis. If there was short somewhere I would have expected to see the "protect" message in the display but thats not showing up either. Sort of fearing that the amp section may be dead (lets hope not). But would appreciate any other ideas or suggestions.
