M3700-32 No Meters, EQ, Mute, dim LEDs

[Darren Reynolds]

Hey all,

Just picked up a used M3700-32 with automation, got it all cleaned up and it looks great! Everything seemed fine, meters and LEDs, automation, etc. was lighting up properly. Today I went to test all mic inputs, and when I engaged power on CH 1, I believe things went south. The mic inputs and faders are working, master section is fine, but now the channel meters, eq, and automation do not work, along with dim or no LEDs for these functions.

All fuses are good in the power supply, currently trying to see if one of the cable pins is not delivering power.

Any ideas? TYIA!!

Oh what a bummer! I hope u get it solved, maybe a component finally popped and just needs a replacement.

There was a bad voltage regulator in the PSU, no +12v, got it fixed yesterday and today things are looking a lot better. Now, likely due to some re-assembly mishap, everything is on all the time! All automatable functions are enabled.. and all LEDs are on .
Now I have to see why this is..
