Wow. You chose to install the display, but not install the cable while you had it apart? OK...
No, I had the screen first. Tried that, then ordered the cable. I have the cable now, but have not installed it yet.
I put the original screen back in, in order to use the laptop.
I am actually going to install the cable now. Let's see what happens.
EDIT - After disassembling the whole laptop, switching out the cables. I have the same result.
I do not see the bios, but the screen itself lights up, so it is getting power.
EDIT 2 - Whilst replacing screen for the old one, to see if it worked with this new cable. It appears that is in fact the same cable! The forum I obtained this part number from is incorrect, and cost me £30! However, I have found another cable, which is only £10. I will order to see if it works!
I have now ordered the Part Number MPN 50.4RY03.001. Let's see if that one works. I am going to try my hardest to get this 1920x1080 screen to work!!
