Switching power supplies are not easy to troubleshoot. The power levels are high and the safety margins are thin. Because they use feedback circuit methods it is difficult to isolate the problem.
If you want to be successful with electronics you cannot just use parts you happen to have on hand at the moment, there are too many variations and you know too little.
Modern electronics are harder to find the right parts for because things are seldom documented well because few people will have them repaired. The repair costs are too high. Most people will simply buy a new unit.
Please do not open many threads on one unit. It is rude.
