Guys,
I have a Hobbico field charger mkii, and it has ceased to charge! In fact, it will not turn on. The fuse checks out ok, and I have removed the panel/board from the case and visually, no signs of anything being cooked. When plugged in to the 12v power supply (deep cycle marine battery), I have plugged in a 5-cell battery into one of the charge ports, and a voltage meter in the meter ports. The meter reads the battery voltage, but pressing the charge button has no effect.
The charger is out of warranty by a year, and has worked flawlessly until now. Sending it in for repairs is not cost-effective, so I'd like to repair it myself. My knowledge is limited, but if I had a schematic, I'd at least give it a try.
So, all that said, does anyone know what I might look for first, or have a schematic? Any help would be appreciated. Here is the mfr's. webpage for the charger:

Thank you,
