yes,sorry I know not how to do!...

Photos are not mine, but the board are the same as mine.Photos are 1550x1397, and logic is 800x600.for me do not seem too small!
I certainly understand that you do not repair a circuit looking at the picture!
I would just like an idea,What I can measure or what i can replace.

So if the drive works well, is the logic wrong? I remind you that the status LED is always orange, and the power button does not work.
You said:"The logic card does not use the 13.8 volt supply."
did you see in the photo that the pin 13 of the inverter goes the 13.8 vcc
to logicboard?why ?
excuse my many questions: I try to understand.
ultimately:you think that I must replace the logicboard or what?

yes,the problem is not the fuses,why the problem is not the absence of tension, in fact I find more tension than normal!what I want to understand: it is the higher tension that inhibits proper logicboard or the logicboard is gone?
and also: because I find tension higher than normal?
sorry, I hope I explained the concept.

hi,
These are photos of the inverter and logic board.i asked to myself why i found
15,3vcc with no load,and 16,8 with logicboard connected:i should found 13,8 !
maybe it is corrupted the logicboard? or voltage is too high for its smooth operation?...

hello,
this is very interesting forum.
I also have a problem with this inverter:
monitor is dark, LED always orange and power button not risponding.i replaced the two MOSFETs and two capacitors which were bulging (C204, CE101), but the situation as not changed:the problem is not resolved.i measured output voltages:
I have the 5Vcc, but instead the 13.8 vcc i find
15.3 vcc, why this? You think that I must replace the logic board?
wait an help .thanks in...
