I have problem with K53T. On external screen everything seems to be fine, but on internal screen no screen at all. I changed bios, lcd cable, led screen, gpu bga but nothing has changed... I don't have schematic diagram for this motherboard (QBL60 LA-7552P). Any sugestions?

Hi!

Video should be set to priority. There is a possibility to do it in the BIOS or Catalist manager.

take the scheme and will repair http://www.elvikom.pl/forum/viewtopic.p ... 2P#p114936

Video is set on priority. I don't have points on that forum to download scheme... ;/ But could you give me a slice from this scheme with Travis LVDS Translator? (page 26).
