Could be the board itself that is dirty on the machine. If it is it should be easyto clean. Otherwise it might be something else that could be the problem but since it does not bring up the error code itself. I would definately get it myself if money was not too tight here and do a simple leaning on the board itself to see if it would improve. then run some tests to see if it is a component itself that is defective.
For $250... do you guys think it is a board issue that needs to be cleaned?
If the board needs replacing, how much does it cost and where can I find a new board?
