I've got a 4 year old Eagle Fishmark 320 that will not power down unless you unplug the power to it. I replaced it with a Fishmark 480, but would like to get the 320 fixed to go on my console. Other than this problem, it's in mint condition. Eagle wants $100.00 minimum to repair. Anybody have a clue how I might can get around the $100?

Thanks for any help
