Step 8

Remove the display cable carefully. It is very thin and this particular one had some clear tape holding the cable to the panel. Remove it if it is present and disconnect the cable

Step 9

Here is the only shortcoming of this kit as far as I can see it. The menu buttons are on the same side as the cable connector, it will get in the way of placing it in a case. Some re-soldering may be necessary
All it takes to connect the driver kit to the LCD panel is to plug it in. The connector is a perfect fit.
This kit offers HDMI, DVI and VGA input. I opted for the VGA for testing purpose

Step 10

The LCD driver requires 12Volt to work, I used a spare 12V 1.4A switching power supply. the LCD fired right up and displayed a crisp image.
Only shortcoming on this kit, the push buttons for the menus are in the same direction as the cable connector. Otherwise this kit definitely exceeded my expectation.

Now its time to think about a case for the monitor. Great little project for a rainy day and it does save another LCD panel from the landfill.

Hello, Nice work…i have v56 universal board with LP154WX4 (TL) (C1) ..after the firmware is installed …i just get very light blue color display…not able to figure out the problem ? can you please suggest….?

James Nielson - Feb 15, 2019

Another issue, if it’s like mine, is that the color accuracy (and bit depth?) isn’t too good. I used an LCD out of a top-end 2008 Macbook Pro, so I know the color should be better than it is.

VALEN FRANCIA - Sep 29, 2020

does the board support 14’’ lcd screens?

oldturkey03 - Sep 29, 2020

that will depend on which board you have and if it is listed as supporting your monitor. The trick here is to match the monitor with a driver board. Always verify this with he vendor.

Same here. In my case I have a pile of LCDs but the problem is most of them are the older type are CCFL backlit.

Unfortunately there aren’t that many applications for a CCFL VGA 14.1” panel but anyone who does come up with one please message me “darnstadium
