Turns on but does not generate 110v, a very low voltage appears (20v). | Fets q3 and q2 shorted, r77 (8r2) open, ic6 no pwm waveform. | I found a video on YouTube by a blessed person who showed how to check the pwm waveform with an oscilloscope. If you search on Google for the board code (pciv023532) a page on the electronicabr forum will appear that has a partial diagram of the power part, it helped a lot. I solved it by changing the 2 power fets, the 8r2 open resistor and I also replaced the 2 pwm. In my case, I still had the 15v line from the pwm that was open, I redid it with enameled wire. it became new. | 2000 |
