回答“No backlight and LCD replacement didn't fix it.”OMG! I thought it was a short circuit.. IT wasnt. LISTEN PEOPLE. your screen does actually turn on but you can't see it. under a specific amount of light you will be able. TURN IT OFF THEN BACK ON! I thought this wouldnt work BUT it WORKED! PRESS THE POWERBUTTON FOR 5secs THEN SLIDE YOUR FINGER TO TURN IT OFF EVEN IF YOU CANT SEE NOTHING SLIDE IT MULTIPLE TIMES THEN WAIT A MINUTE THEN TURN ON. (AND IT WILL WORK) ITES NOT A SHORT CIRCUIT.
