Invasion of Arions) another lamp and again a problem in the same place. However, now the damage is greater. The entire primary burned out along with the PWM and the power switch, the canders (films, electrolytes) and the snubber diode also flew out. I was lucky to find spare parts, took the last two PWMs for the whole of Minsk =))) In general, watch the video comrades, all successful repairs!
P.S. with all this horror on the board, the fuse remained intact O_o
P.P.S. I bought a couple of transistors and did not dare to install them ... the tester showed that this was a galling overmark, I had to look for an analogue from my stocks :(
