Google turned up nothing except checking the boards, which I will do but hope to avoid.
Sounds like a few things to check:
1. What is your AC line voltage, at that outlet?
2. Check the connectors at the transformer. Look for any corrosion
build up.
3. Check the voltage levels into the powerboard, next to the fuse.
4. Lastly, you may have bridge rectifiers that are ready to be
replaced.
