Good Day! Long story short, loaned the phone out working, got it back the screen isn’t displaying anything. iTunes finds in when it’s plugged in to my PC, the vibrate works as proof of life. SO, I replaced the whole front panel glass, lcd + digitizer. Hoping that would do it.. Not that I’m a pro, but that didn’t fix the problem. Here’s the QUESTION. What else would make the screen not work besides the parts I already replaced? Almost any sugestion would be helpful! Thanks in advance. Regards, 52 y/o noob.
Hi, let’s get this figured out. Do you have a microscope by chance to view the motherboard up close? First…and this probably won’t work to be honest but goal is to rule out everything, do a reboot on the phone. Hold home and power down at the same time for no less than 45 seconds. Also if you have another screen to test that would rule out it being a faulty screen. It could be your lcd connector has damage to it on the main board or an issue with backlight ic or backlight filter. First I would strongly recommend test another screen and try the reboot. You could also try restoring if you’re not worried about losing data on the device. If these three dont work it’s a motherboard repair job.
I think it is not the problem of LCD Touch screen,it is the problem of mainboard.Maybe you can go repair shop to test mainboard. My cooperated friend told me about it,he is professional. http://www.eddogo.com/
