The full schematics are available so you can easily check what the problem with your board is. I am sure the problem will have been seen before so Google will find a solution I am sure.
Mjolinor,
First off I want to thank you for your kind help and support. It is really appreciated.
The new motherboard arrived today, i installed it and it works. I am doing the first "test print" right now. All looks good so far except the "platform leveling" procedure is not the same, quite different. I will call where I bought it from and get some instruction about it.
Thanks again,
Don
