repairing canopy power supplies

We have a number of decessed power supplies due usually to customer grounding issues. Has anyone had any success repairing these?

Its cheaper to buy a new one.
Charge it to the custumer…

Repairing it opens you up to liability. If a fire starts at your power supply you will be in a world of crap.

spend the 8 bucks.

The trouble is once you crack open the canopy adapter, it cannot be closed back. We bought 24V 400mA adapters and just attached the canopy cable onto the circuit board.
However when testing it they started to heat up alot. Probably my soldering heheheh.
