What wire connections inside phone controls turning on screen
Had to repair the sim card reader for HTC Desire 610, so took the phone apart and made what I think is a fix (won't know until I can see the screen). I was very conscious of wiring schematic, but when I put the phone together and turned it on, it vibrated, played ATT theme, but the screen stayed black! I obviously missed an important step or connection when I put the phone back together. Any help would be appreciated.
Is this a good question?
