Hey,

I know this may be the wrong forum to post this but I am eventually going to use this 10.4" lcd and ELO SAW touchscreen I have to control my blinds in my room via Arduino.

I have a NEC 10.4" LCD Display Model No. NL6448AC33-18, and inverter board along with an ELO Touchsystems 10.4” glass touchscreen (SAW), ELO touchscreen controller Model No. CTR-250000 (the serial one).

I bought a LCD controller panel off ebay. Here is the info on it. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&Item=180232630831&Category=61398&_trksid=p3907.m29

  • 1x 110~240 12V 4A power adapter (power cord not included)
  • 1x Controller to LCD Connection Cable
  • 1x VGA Cable

The VGA Cable was made custom for the panel. For some reason the guy made the end of the vga cable male. I wanted to test my xbox's vga singal to the LCD panel but its end was male, I tried making a gender changer connector but when I hooked it up the LCD panel was making a crackling sound. I am getting a proper gender changer in the mail tomorrow to test if I can run windows or xbox360 on the LCD Panel.

Here is my question. The VGA cable had a black (what I think is a ground/earth wire) coming out of it with a metal loop going towards the board which I assumed gets put underneath a screw on the back of the lcd panel's metal frame. Is this correct or does this wire go somewhere else.

I have a picture to illustrate what I have done.

I want to place the control board and inverter board on the back of the LCD panel, there are holes for mounting but whats the best way to mount these boards to the back of the LCD Panel.

The scary thing is that the panel shocked me when I had everything hooked up, I thought I had everything connected correctly. It was the metal frame of the LCD panel that shocked me. :cry:

I probably should have just got an enclose panel instead of piecing this together, but where is the fun in that.

The cable with the ring terminal is probably an earth ground. You want to connect it to the metal chassis in your enclosure. Of course check the documentation to verify.

If your lcd uses a CFL backlight then it generates a few hundred volts. Be careful around that LCD. It may not kill you but it will get your attention.

For mounting you might can take some double sided foam tape and secure a piece of plastic to the back of the LCD. You can then attack your boards to that.
