I recently replaced my Acer laptop screen, over the past few day the screen started to dim. Thinking Oh Man what is next! I fooled with the setting and buttons to no avail thought the inverter is going, then I wondered if anything I did was causing the issue. I decided to pull the face off and yup the screen cable was not perfectly in its slot, it was very lightly squashed I made it round again and fire it up dimness gone. Even though the cable was not damaged the pressure from the face plate made not pass its signal correctly (no gauss theory). I posted so if it happens to any of you check your wiring, may save you from buying a screen inverter.
