Update on "fuses"; Firstly there is no voltage on the capacitors, secondly I cannot find two resistors but there are two markings (R3& R4) where you suggest. I can get no reading on them by using the holes through to the PCB, would this confirm an open cicuit or blown fuse? It is along time since I could read the values even with a chart

Martin, very enlightening. In my stupidity/ignorance I was looking for a glass tube with a wire inside !! This gives me hope and would point to no sound but all other functions working? Top off tonight for another poke around.

Hi, sounds like you have the same bug as I. See silent 6500. Will be interested to see your fix.

Thanks, that was quick. Unfortunately I have checked the voltage after the fsue (T4?)the one beside the big caps. Does 10.8v sound right? Also the other tapping is giving 28v. I have seen reference to overload in respect to the speakers but as they were on tickover I cannot see that as the cause. Fantastic forum ! Just spent the last few hours trawling

Hello all, a bit new to this so be patient. My 6500 has gone all quiet although every light,bell and whistle is working and it is still talking to the MCP. Mute relay is OK, I think, and I tried the second speaker conections, as well as seperate speakers. No smell of overheating,no scorch marks any where. Should the fan spin on switch on, or is there
