You can also take 5 volts from the ribbon cable and bypass using the old inverter's 5 volt source Sent from Yahoo Mail on Android On Wed, Mar 2, 2016 at 12:42 AM, Mark Lewis misterhemi@...

There was a link to this LCD: http://www.ebay.com/itm/240x64-Dots-GLCD-Graphic-Module-LCD-Display-w-T6963-Controller-LED-Backlight-/301017374539?hash=item4616089f4b:g:xIYAAOxy3NBSjrnw I decided to purchase one after the original poster said he successfully replaced his LCD, I was able to replace mine and later I should do a write up. However there are a few tricks/tips you’ll need to know. First, if using the original LCD’s ribbon cable you’ll need to desolder it and make a slight notch or indentation on the header using your soldering iron.This is because there is a surface mount capacitor which interferes with the header, the notch is very slight but provides the right clearance. Secondly, you’ll need to put a pull-up resistor on one of the pins so the font is set to the correct 6x8 mode. By default mine was in 8x8 mode which will cause some of the text to extend beyond the display area of the LCD.I used a 10k 1/4 watt between two of the pins (I forget which ones at the moment). Third and last, you’ll need to remove the inverter and place a jumper on the power supply board to provide the 5 volts needed by the LED back lighting. You’ll also need to use the brown & green wire pair from the old display to provide the backlight power. It’s nice bright and silent (no inverter noise). It looks very good.
