Hi everyone. I'm new to the forum and I think I posted this in the wrong section the first time. I have a skar skv2 2500.1d that blew a few caps. I replaced the caps and the power supply seems to be back working. The output section I not working correctly. I'm not getting switching I think it's called or square wave. I was gonna try replacing the chips on the driver card but they were scraped off. Could someone identify these parts for me please! Thanks

One in the middle by the rectifiers and one on each side of the output section. You'll get a email from me sometime today I'm gonna purchase the guide. Have to get another laptop. Thanks for the reply
Do you have signal into the driver board?
Are all of the DC voltages present on the driver board?
Do you see any signal on the output filter inductors (check both terminals of each)?

I don't know what voltages go where on the driver board. But I do have a plus and minus 12 and 5 volts going to it. And no signal on the output inductors. I just realized the Kia 7912pi and kia812a are heating up
On the driver board, what's the resistance (measured from collector to collector, vertically) for each driver pair?
