Hi All,
I came across this thread when looking for solution for the LOW RES problem on the NX75/EVO75. I started suffering from it after I had dropped my mod by accident. I'm posting my solution here in the hope that it may help others.
In my case, it was a large surface mount chip in the center of the back of the PCB that had come loose on one point. (I'm guessing it's some kind of regulator, it's the biggest package on the board) After soldering it back in place the mod worked like before. You could also wedge it in place by putting a small piece of paper behind it, if you can't solder it. Looking at the size of the solder joint, that chip should not have come loose. I blame bad solder work.
You will need a T5 Torx screwdriver to open the modbox.
Best of luck.
