My expectation is that you will pin point the problem since you're an expert. I already knew it's computer board related and had hope you had seen this issue before with the ability to point me to the exact board that need replacement. Sorry to say, but I am not satisfied.
Have you experienced this problem? If so, what was the issue?
Do you recommend replacing the main board or any other related boards?
