Turns on, turns off or the LED just keeps flashing | After examining all the capacitors on the power supply, I found a polyester capacitor on the side of the TM801s, a CS810 with 10NF 630V, which didn't show anything on the capacitance. I took one to compare and saw that the CS810 was open without any capacitance. It also causes the icm801 ci of the high power supply to burn out. | Replace it and the power supply works beautifully!! | ARIELTECH |
