Apple iPad 9 (A2602) backlight issue / no backlight
Hi,
No backlight on iPad 9. Made some measurements around LCD connector, please find on attached picture below.
Filter marked with green star has been replaced since it blown.
Yellow values measured relative to GND. Red ones measured on components. Filters seems to be ok, but before and after the replaced filter the resistance is very low. Is it ok?
Thanks for the suggestion. With that dump from post #27 machine boots into Windows, I can hear when plug in or remove a USB device and machine plays a tune, however there is no picture. Not on internal or external display (HDMI).
Is it still a BIOS issue? In previous posts others also mentioned this problem....
