i7 x220t - LCD Backlight works but no display

#1 Post by TheForgottenKing » Fri Jun 08, 2018 1:58 pm

Bought it off ebay, going to nitrocaster mod it anyway but would be nice to get functionality first

Checked
-External Display works
-BIOS settings reset
-Backlight works
-Backlight control works
-Boots into windows fine
-In windows, display detected but black, windows open on internal display
-Different LCD and cable
-F1, F2, F6 fuses continuous
-Displayport dock works
-Displayport motherboard works

What fuses or other things should I check?

Return it for a refund and buy a regular X220/X230!
nitrocaster's mod is NOT for X220T or X230T tablet, only for non-tablet machines.

I know it is not but I plan to try, the mod fits with some small mods, I knew going into getting this one it was damaged but hopefully it can be fixed.

It being a tablet, I'd check the LCD-cable.

Try the LCD on another working X220/X220t with that machine's LCD-cable.
