Thought i would update - indeed it was some short on the power board.? Got the new boards, slapped it in praying i would get back to at least seeing the USB drive but in fact the QMX booted up and was working just fine.
...until it wasn't.?
Made CW and FT8 QSOs and was hitting across north america and into europe on RBN then suddenly nothing.? I am assuming i somehow popped my BS170s??? no power showing as output on teh diagnostic screens, otherwise everything seems to be within optimums as shown in the operating manual.
Any thoughts?
?
Also, my screen is retina-seering bright.? No contact between screen pin3 and power board as suggested elsewhere.? i have removed the r306 and put in a 110ohm resistor.? Brightness has come down, but i am still at the very counter-clockwise end of the contrast control to see anything.? Any movement of the pot counterclockwise and the screen washes out.? Would that be indicative of anything underlying problems or is that simply the screen's nature?? I have much better contrast control on my old QCX mini
