My 2nd hand 2B doesn't work

[ProfZarkov]

Hi, I recently bought a 2nd hand 2B - I know if it looks too good to be true....
I've sourced a PSU and cables and they all check out.
The unit powers up (firmware 2.122B)
I can run thru all the modes
Change power level
Do a factory reset
The blue LEDs flash on the outputs
But no output at all.
Pushed the power up to beyond 50% on both channels and not even a tickle
I guess some output stage was blown .
What's my options?
I'd love to get it working & enjoy.
Hopefully the admin staff can help..
