TC Electronic RH750 - power issue (I think?)

[Paddy777]

I’ve got a TC RH750, I turned it on and after a few seconds the power died, now when I try and turn it on the lights flash on for a second or so the the first time, and then nothing, so I’m guessing it’s a power issue? I know the general consensus with Class D’s is that repairs will cost more than replacements, but with it maybe being a power issue, is it something possibly repairable or should I bin it?! 
 

Any advice would be appreciated
