Ipad Air A1474 has backlight but no image

Ipad Air A1474 has backlight but no image.

The tablet is turned on, there is sound, the backlight is visible, but there is no picture.

This happened after changing the digitizer and I guess the reason is that I did not isolate the battery before.

I found a missing component near the lcd screen connector. I'm not sure if it's relevant to the problem?

The missing component is C7046 (0.1uF / 6.3V / 20% / 01005 / X5R). This capacitor is "inline" and used to filter the EDP_DATA_N<2> line and as such, it has to be replaced.

Such small components are difficult to DIY repair so your best bet is to find a repair shop that does micro-soldering repairs.

Thanks for the quick response!

Is the absence of this capacitor causing no image, only backlight?

tarafından

I think this is not the missing component because the missing component is between the two sockets J7000 and J6620.

C7046 you mention is on the outside of the J7000 ?

It doesn't show on the schematics available in the wild but it does show up in ZXW Tools.

Try simple things first like hard reset, put off battery press power button for 20sec, install battery again and try to turn on the device. If problem exist then seems you made a mother board damage, maybe you removed a small part like capacitor or filter. You need to see schematic and compare with your motherbowrd
