After much deliberation and second guessing, I finally started my first mod tonight. After struggling immensely with proper soldering (and desoldering) technique and testing all my connections with a multimeter, I powered on my DMG and was sadly disappointed to find that none of the LEDs turned on. The actual DMG seems to be functioning perfectly. I'm afraid I've damaged the backlight, but am hoping that's not the case and was hoping someone with more experience could clarify.
I'm using a V5 backlight from Nonfinite.
I am attempting to install a rocker switch to power the backlight unit.
Here's how I wired it:
The backlight's positive lead (which, confusingly enough, came with the black wire attached to positive and the orange wire to negative) is soldered to the left of the two contact points located immediately above the capacitor nestled under the LCD. The negative wire loops through the hole around said capacitor and reaches up behind the PCB to the top right where it joins up with the rocker switch (I've read it doesn't matter which prong you connect to in a 2-way switch like this). The other prong goes back around the front and connects to the other lead above the capacitor below the LCD.
I'm really hoping that I just wired everything wrong and that the unit isn't damaged, but there's a chance I did a severe number on it while I was peeling off what I thought was the protective film. I wasn't being attentive enough and hastily pulled the white plastic piece away from the plastic piece which houses the LEDs and respective circuitry. On seeing the circuit, I said: "oh shit" and stuck it back together using the tape that was already on it and what was left of the adhesive. It's still a bit loose, but it holds in place.
I know they aren't ridiculously expensive, but I'd be super bummed if I ruined a perfectly good backlight.
