Fender Acoustasonic Jr. DSP Effects troubleshooting help

[jasonguitar]

I have a Fender Acoustasonic Junior DSP that I've owned for a few years and I really enjoy it but the effects suddenly stopped working. These amps are not my cup of tea to work on. I though I'd see if anyone here had any experience with these or might be able to point me in the right direction with some troubleshooting tips. Thanks.Acoustasonic_Jr_DSP_schematic_Rev-B.pdf

The DSP Test Points are clearly marked on page 3 & 4.

I've seen a couple with ribbon cable/connector issues.
