I would like to decouple the display and the base of my old laptop (Dell Inspiron 5160), so that I can place the display anywhere I like (sometimes as a digital picture frame). For this, I need to make the LCD cable much longer than it is now. Since the connectors are way too tiny for me to mess with, I tried he following simple idea: For each of the 25 wires of the parallel LCD cable, I cut the wire and then re-connected it with a longer wire. I got through 21 wires and it still worked, but failed after that.
Could anyone tell me why?
Here are some more details:
- The 25 wires are of two colors: 8 blue + 17 red. 9 of the red ones go into the inverter; and all the blue ones go into the video.
- Each of them is a stranded-wire. Furthermore, each blue wire has an ultra-thin copper layer between the conducting strands and the outer insulation. (I am not sure whether the copper are electronically connected to the wire inside; neither do I know exactly what the copper layer does. I guessed it's there as a shield and for grounding.)
- Anyway, I successfully extended all 17 red ones and 4 blue one, but failed the 5th blue one (The display now shows no text or image, except color changes: blue, green, red, grey.... I try a good LCD cable and the notebook and the display still work fine.)
Apparently, there is something about the blue wires (including the copper layer) that I don't know. By cutting and reconnecting the wire, I basically cut the copper layer into separate sections.
