Speaker pop on amp startup - 1 channel only

I have an amp (Sony TA-N90ES) that makes the left speaker only pop as it comes out of protection. With a VOM I measure about 5VDC on that channel for a split second, quickly diminishing to zero.

I got a very good deal on this amp because of this but I would like to figure out what is going on. Any suggestions? It is a solid state MOSFET amp.

That is what I plan to do but I would like to figure it out - I want to know if it is something that would affect sound quality or if it is just the equivalent of a cosmetic issue.

Sorry for the jest, but I imagine there are many things that could do it. Without a schematic it is hard to tell. I tend to leave SS gear on regardless. Leave it on or get it fixed, lest you take out a driver passing DC. I'd have it looked at straight away myself, in case there is some sort of bias mismatch or a part nearing failure -even if it sounds "right".
