I had a broken laptop and I wanted to take advantage of his screen, so I disassembled it and noticed that the display is a Quanta QD15TL07:

So I found this controller board on eBay: http://r.ebay.com/94mdmr Model M.NT68676.2A

enter image description here

The problem comes when I've connected it to the display, the image is shown four times on it:

I'd like to know if anybody has experienced the same problem or if you guys know if I have to change something on the board... because I don't know what is going on with it.

Thanks in advanced.

  • Wrong sync signals? Wrong resolution? – dirkt Jan 24 '17 at 17:22
  • How can I check that?? I don't think the resolution is a problem since it doesn't matter if I connect something to the display or not, it always shows the same way. – JV Lobo Jan 24 '17 at 17:28
  • If the controller board puts out, say, 640x480, and the LCD resolution is 1280x960, you'll see 4 frames as four images, like in your photo. Do you have a manual for the controller board? Diagram? Anything? – dirkt Jan 24 '17 at 17:32
  • On eBay description it says Max Resolution 2048x1152: i1244.photobucket.com/albums/gg564/oupin/1-9878_zpsj9p9nuu7.jpg I've also found this manual with diagrams: vslcd.com/Specification/M.NT68676.2A.pdf and also another PDF here: elecrealm.com/down/html/?39.html Thanks :) – JV Lobo Jan 24 '17 at 18:05
  • Did you try to get into the "factory mode" as described in the second link? Are there any other menu items besides those visible in the picture? You shouldn't touch brightness, contrast, and the color temperature settings, but maybe "LVDS Map" does anything useful? Also see here. – dirkt Jan 25 '17 at 9:12
