Respuesta a "Dark Area in Screen on iPhone 7 plus Even after Screen Replacement"Most likely a backlight filer that blew whilst attaching the connector without disconnecting the battery, although the problem may be with any part of the backlight circuit. Mine smelled burned. This guy has the same problem and fixes it here: https://www.youtube.com/watch?v=bVoEDR4O... If you peel off the tape covering the circuits you can examine it for dark, burned filter. 95% of time it’s the filter according to this tech’s experience, although it could technically be any part of the circuit (coil, diode, connector). http://www.ipadrehab.com/article.cfm?Art... Anyone doing this repair? How much should I expect to pay to get it done? Can’t you just replace the filter instead of the jumper? Looks harder running a jumper and less reliable of a repair.
Respuesta a "Will replacing my screen also fix my backlight?"Not necessarily. It could be a problem with the backlight controller or back light filter on the logic board. Check this repair out, that fixed a dark spot on the screen caused by a fried backlight filter. https://www.youtube.com/watch?v=bVoEDR4O...
