Coming up short on googling for routerboard repair services. Does anyone have sources for reputable repair shops?
Have a few 500 series units acting a fool.

That would depend on what the problem is. If it's capacitor replacement, then it's pretty simple and inexpensive. If it calls for a lot of diagnostic equipment and surface mount rework then it will probably be cheaper for you to just buy new boards.

Right. So I should call......?

Well, for a new board, call your distributor.

To fix bad capacitors, either call your distributor for RMA... or call practically any electronics repair shop to fix outside of warranty. They don't have to know anything about Mikrotik to swap out the capacitors.

There aren't any "official" Mikrotik repair shops... the RMA/factory does repairs.
