Dear All, I got a bunch of used EV TG7 amps and one of them went into protect mode shortly after power up, no load, others thumping fine. The display shows an error message "HF/DC/HOA-Failure A. Output mute" (see attached pics). On a simple google search, seems this is a common problem, and for some it is recurrent ( https://www.fixya.com/support/t10439138-when_switched_tg7 ).
Another guy listing a Dynacord H5000 (Same amp internally) claims the same issue.
Apparently EV wont answer any questions and wants them shipped to their workshop, an option that is too costly for me given the distance.
Any ideas on where to start??

So my tech opened up the amp and we found a blown fuse and a loose solder joint.
Amp is fixed and worked for a 12hr show yesterday.

That is good to hear. I really like it when people post a follow up and what they found.
