M200 How to change backlight brightness
I cannot find a guide for this at all. I know that I will need pots and all that, but i cannot find the resistor on the board that I will need to replace. Anyone have a guide for this? Even a little info would help. Thanks -Syco54645

I just made a new topic on manually turning off the backlight. If you're planning to add a resistor/potentiometer, I think we're looking for the same pin. If I find it, I'll post it in here, too. I'm still trying to get my camera unlocked though, hopefully it can get keycaught soon!

http://www.rpi.edu/~bradfe/NVG2.html ADD BRIGHTNESS ADJUSTMENT The other wires in there are for a mute switch (you don’t want those annoying noises if you’re sneaking), the USB cable, and a brightness adjustment resistor. That last mod is imperative if you’re using this for night vision. The screen is way too bright to hold up to your eye if it’s dark-adjusted. To do this, trace the screen backlight’s power leads on the ribbon cable that connects the screen. They’re easy to find, they’re the odd ones that have a separate cable piggybacking on the main one. Holding the camera upright with the screen unscrewed and flopping down, trace the power lead on the right to its pin on the connector(it’s something like 13th from the right, but I forget). From there, trace PCB leads to one of the surface mount resistors on the board. I don’t know which one it is because I did this mod a while ago and didn’t record it. Carefully remove the 50k resistor and solder two wires to its contact pads. Run these wires off sideways and screw the screen back down. Find a variable resistor you like that has an appropriate range and preferably a small knob, and connect it to the wires and mount it on the side of the case. This will now adjust screen brightness.

that page does not tell how to do it, merely to trace it to a 50k resistor... from what i can gather on the forums it is a 470 ohm resistor... i emailed that person and he was of little help and told me to trace it myself. I have found the 470 ohm resistor that people are talking about R82 but am not sure if that is correct nor do I have any idea what potentiometer to get. Further, I have read about them but cannot figure out what the 100K number refers to. Is that the least amount of resistance or the most. If it is the least, what is the most. If it is the most, what is the least? I have yet to find these answers anywhere.

So I suppose no one has the exact way to do this?
