amp I bought 3 days ago not powering on - electrical engineer advice wanted

thanks markus ! It's certainly worth a try!

Whatever you do, once you get it sorted, solid state equipment should be not be turned off.  This practice minimizes stress on the inyernal components and likely allows the unit to last longer.  Turn it on and leave on.

so for a couple weeks it mostly turned on, after a few tries. This week it mostly didn’t. The repair shop I frequented gave me the cold shoulder for no apparent reason, so I finally opened it up. I bet it would be a simple fix but I don’t know what I am looking at. There a button that goes in and it turns on the power, I assume a mechanical step to close a gap? Should I just replace that board?

What did musical fidelity say?

Should I just replace that board?

No.

You don’t say

Really? For no apparent reason? 

Look, like you’ve been told before, the fault is more likely than not in the protection circuitry. You have two options: 

- As @patrickalston advised, whenever the thing decides to work, leave it on. 24/7/365.

- Find a good tech and don’t antagonize them.
