Resposta para "Replaced screen on Surface Pro 4, digitizer works but screen doesnt!"I am suffering the same issue here on an SP4 after replacing a cracked screen. The new screen and flex cables work on a different SP4 but not on this particular SP4. While plugged into a display port unto a projector, everything works, even touch screen (although only in drag mode). Is it possible that something got fried on the motherboard? I desperately need a fix.
