Backlight but no display after battery replacement
I have just replaced the battery in a stock IPhone SE for a client. This is the first repair for this particular phone, and the battery did not charge prior to repair.
During the repair, I used parts from iFixIt and followed the guideline exactly. Upon completion, phone worked as normal, so I returned the phone.
The next day, they brought it in to me and I see that the backlight works, but no display. I have disassembled the phone again and made sure all contacts for cables are secured and that nothing else is out of the ordinary, which it seems there isn’t. However, still no luck.
I can feel the phone vibrate when resetting (both soft and hard reset), so I know it is actually turning on. The backlight also works, just no image on the LCD display.
Any help is appreciated and any tricks will be used if available. Thank you in advance.
Esta é uma boa pergunta?

I'm also having this problem, but with an SE 2nd generation. I did turn it off, and removed the battery before operating. After doing a screen replacement, the iphone worked perfectly, until I turned it off and turned it back on. The backlight was on, but was not displaying anything.
From what I know after someone else had worked on the phone from a shop, the owner ended dropping it again, and left it dormant buying a new iphone. Later he asked if I could fix it, and honestly I should have asked more before saying yes. When opening the phone it had no glue seal, dirt and grime built up, and the shelds that cover the connectors were gone for both the camera and button/display. I did clean up as much as I could, and everything was going well until the display stopped show properly.
I do have a digital microscope, and checked the pins on both the motherboard, and screen. I don't see any problems on them, and I have little to no knowledge on compactors, and resistors for this phone. :(
