Marshall avt 100 - no fx

[deko]

Hi Guys

The Digital FX on my Marshall AVT 100 has stopped working (sound completely dry)

I've had a cursory look at the amp but all wires seem secure and in their place.

What / where shold I look to rectify this problem?

Thanks in advance

There's a high probability that the DFX module has gone bad. Pretty common in other brands, not so much in Marshalls, but still possible.

You need to scope the FX signal path to find out...

Verify that the 5vdc supply is getting to the FX board. You may have a failed 7805 reg.
