Problem description
iPhone XS & XS Max uses an OLED display. This mean, there's no backlight, but many people will still diagnose No Image as "No Backlight".
Always make sure to test with a known good screen, to rule out a parts issue.
Symptoms
- Phone turns on but nothing displays on the screen
- Screen always stays black
- You can hear sounds & feel vibrations.
Solution
- Diode mode the display connector (J5700) & check for any shorts or OL (Open Lines).
- In most cases, you'll find PP3V0_DISPLAY_CONN filter FL5783 is blown & needs to be replaced.
- In other cases, you may find one or more of the 5 chokes L5700, L5710, L5730, L5740 or L5720 is damaged or broken from pry damage
- In rare cases, you may discover there is long screw damage in the screw hole next to the battery connector, which will sever image lines from the chokes mentioned above.
