Default Re: This is Why You NEVER Ignore Bad Capacitors!

I've repaired some boards with this problem (some K7S5As and M805LRs) but they weren't as bad as this one. The MOSFETs were always bad, the rectifiers were always OK. Some of the base driving transistors were bad, some were OK - the older boards have two separate SMD driving transistors for each MOSFET, K7S6A has only two for all MOSFETs (at least they're in TO92 so can be replaced more easily). And of course bulged caps - always G-Luxon.
