So, the third batch of MOS-FETs came in and instantly you could tell, that they were "the ones" since they even had markings and engravings on the metal plate as well, not only on the grey exterior cover. The original ones also had these engravings. I soldered them in and AV worked right away...
Yes, I teared apart only the metal frame of the main case right under the heatsink (attachment 4 in my 31 post). Luckily, there was enough space to work with.
Yes, when first problems with overload appeared few years back, I had taken out original fan, which did not work until the Overload...
So, to follow up on my story: soldering back original MOS-FETs was never really a long-term option. It worked first time for an hour, maybe an hour and a half. Second time it worked 40 mins and then went into Overload. It just went on to decrease every time until eventually it would just work...
Dear all,
I, too, have encountered a OVERLOAD problem few years back. It started with me stupidly blocking the vent on the top of the receiver with huge printer and the problems started off slowly, maybe it would go into Overload once a month which would be cured by turning off and on again...
