You will find coolant has leaked on the board(s) and coroded the connections
between them. Lots of cleaning and repain to be done by someone who is very
familiar with repairing this problem. Don't do anything until you have more
detail on what to do or find someone who is familiar with fixing these.
If you want to communicate more detail post a message at Home Theater Shack
in the service and support forum. I only intermittently check messages here
but I get email notice if someone posts there.
