I have a VM9512 with no audio - no sound in any of the speakers when set to any source. I know it's not a wiring issue because I have another head unit that functions correctly.
I measured the voltages in all 8 of the speaker wires coming from the head unit. 6 of the wires measured 4.5V. The white wires however clearly aren't outputting the correct voltages. The white/bk (-) wire measured 11V, the white, (+) 0V. When connected to the speaker the white wire measures 0.14V.
I guess my big question is, is there any possibility that this issue is being caused by a user replaceable component, rather than an IC chip?
I would appreciate any suggestions.
