Hello MrBrokeit, Shotgunning works sometimes, but the effort spent is often not worth the time spent. Let me explain if your power supply is defective then shotgunning will produce results, however if the problem is elsewhere you will never know it. I would suggest troubleshooting the unit, to determine where the problem really is. For this task I would suggest that you get a schematic diagram of the unit, a multimeter, and an oscilloscope. use the schematic to find the various test points, use the multimeter to measure the voltages at the test points, and then use the oscilloscope to measure the signals at the test points. Troubleshooting in this fashion will produce better results than as with the shotgun method. I would suggest checking for ripple voltage in the DC path. This voltage is due to AC bleed over from poor regulation by malfunctioning filter capacitors. you will not see physical signs of the problem but a quick check of the capacitors will let you know if the is the problem. Also check to see if the DC voltage across the positive terminal of the capacitor is held at the level it should be at. Then check all points on the power supply and compare them to the schmatic. Thank you, Shuttle83
