Thanks for your sharing。Now my AC power supply have a problem, when the AC 220V is on, the relays K100 or K101 are click for about 5 secends ,sometimes the 500mA fuse are broken,now i can not put the power on.
I look the schematic and the repair manual, test the K100 and the k101,they are on and off is good,the u106 and the u110 is good ,they can control the K100 and K101,but the problem is still there .
The AC power problem is hard to test and solve.
