You could try to run a plug in & out of the Eff Out & Eff Return jacks, with the amp off.
This may clear out any crud.
Other than that, these amps can be a real PITA.
There is way too much digital crap in the signal chain.
I would take it to a competent tech.

1/4" plug

Use them Both.

look for some contact cleaner (withlube, if possible). don't spray it the jack, spray the plug. then insert and remove several times, with a slight twisting action.
especially the return jack.
