Hello,

I'm having a strange issue with service on an iPhone 6. I purchased phone for repair & resale. It had a badly damaged screen/LCD, so was dropped.

After replacing screen & testing phone, I found that MOST of the time it will not find service...will display either "Searching" or "No Service". I've swapped 3 to 4 sims out several times. Most of the time it shows "No service", but only 2 of the 4 sims actually have service. Once it finds the service, it stays locked on to it till I disconnect the battery.

I noticed in the settings under Airplane mode...when it finds service the "Carrier" line will pop up for a few seconds, go away for a few seconds, show again a 2nd time, then go away & the sim will show service.

When it's not working...the "Carrier" line is never displayed.

I've tried the following: Cycling Airplane mode several times, resetting Network settings several times, made sure antenna next to batt connector is properly connected, Date & Time setting, hard reset a few times, & did a factory reset. Nothing works. What component or circuit area would likely cause random service like this?

Any help would be greatly appreciated.

1. Problem: When I take off its back and power on, i see the backlight at the side of mainboard, but the side of the lcd doesn't seen. So no display anything and can't use touch.

2. Problem: as i said, in dfu mode it works fine, but when it powered on and connect to pc, its ringing every 10 sec as if cable is pulled in and out circular (as mac seen it is constantly connected). And there is a little hotting maybe above NAND when its connected with usb.

Can anyone tell me how can i fix these issues?
Thanks for the answers!

Update: L28 overheating
