Hi, my QMX does not start. When I disconnect all four boards (2x PS, 1x LCD, 1x controls) I measure about 1 Ohm from VDD to ground. Accordingly, a high current is drawn. I applied 1V and at 500 mA I could only see a very small heating at the processor and TXCO with the FLIR. But they did not get hot. I can not see any real hot spot.
?
I then removed L201 and L202. The short circuit remains. I checked all resistors and capacitors connected to VDD such as R211, R216, R218, C217, etc.?
?
All that remains for me is a problem in the area of ICs 501 and 502 or a problem with the multilayer board.
?
Does anyone have similar experiences? I have ordered a new kit and will measure in advance.
