Dead Trutech 20" Set

You would certainly blow the traces off the bottom of the PCB, I've done it before. If it has a switching power supply, any number of things could be wrong. If it's linear, just keep disonnecting things in the circuit till it stops blowing fuses.

I don't trust rednecks or their "engineering" (spent enough time around them to know better), though I have Mac Guivered/jury riged some stuff back to life. There comes a point when one has tried fuses so large that one may as well connect one prong of the plug to ground, the other to 20' of bare copper wire, tie a ball to the 20' of wire and throw the ball across the nearest high tension powerline to see what happens.

That Monty Python sketch was a classic.

You guys DO know that I was just being facetious & Pulling Your Legs, don't you ? While I think bringing some dead veteran back to life is a worthwile & Noble cause, something like this is, well, prolly NOT worth it, as if it has at least THIS Fatal Flaw, how many OTHERS is it likely to have...OTOH, this is truly a challenge for our cumulative restoration/diagnostic skills. And I KNOW we have them here...This group is likely BETTER engineers than the bunch that designed this wretched piece to begin with, as they were looking to try to make something that "worked" at the most minimal cost imaginable, rather than give the BEST performance possible...

Amen to that! There are countless amazing minds here...I'm sure that we can get it running again, if not better than before!
