Quoted from PhillyArcade:Thanks for the input guys! Every little bit helps! I'd read up on that vibration issue. Amazes me how with today's technology, a component can go bad from vibration! It also makes sense I literally added a shaker motor about a month ago to it! I pulled the board going to do more testing I'll let you guys know what I find!
Just wanted to make sure you have seen this..
