This set keep blowing the transistor q5000 on the Y Main Bd. I replace the Y main and Y Buffer bd. and still blows the Q5000. The VA VS voltages will show up and then drop down when the cable between power supply and Y main Bd. are unplugged. I replaced X board and Logic also. On the Power Supply the 5v.,3.3v.15v. check good. When I replaced the Y Main and Y Buffer Bd I had the X board also unplugged from Y main and still blowed the Q5000 on the Y main. I am lost if anyone can help me I would greatly appreciate it. Could I have a bad panel. When you first plug the set in the Samsung Music that you first hear can be heard. THANKS!(THE LOWER AND UPPER Y BUFFER IS ONE COMPLETE BOARD ALSO).
