Hi Dark Venture, if your somewhat skilled you can tackle the repair,,there is enough information and help all over the net. Replacement boards are available used and new. Manuals are available inexpensively, A little common sense goes a long way. Do some research and determine if the repair using your own invested time and board cost makes sense. I'm a tinkerer and mess with electronic units as a hobby and challange,I have no formal electronic schooling.
Hope you take on the project.
Can you tell me how you have your PRO unit connected
