iPhone 6 backlight. Apple logo then no display

After a screen replacement the iPhone goes to the Apple logo for about 3 seconds then lcd dims completely. Have tried multiple screens. Phone still reads in iTunes. I don't want to try restoring just yet because of customer data.

I already replaced the filter and still showing same behavior. Tested the three caps for shorts and all are good. No signs of shorts anywhere in circuit that I tested.

Coil itself visibly looks good with no signs of damage. Also main lcd connector shows no signs of damage.

Does anyone have experience whether this is possibly the diode or driver ic? Since it's near the cpu I want to avoid as much heat as possible.

Any suggestions would be great, thanks again!

the error cannot be grounded caps as you see 3Sec of live LCD, check with original LCD which is phone had.

Thanks for the reply. I already tried original (2 in fact) lcds and same behavior. I'm wondering if boost ic is giving enough voltage. Gonna play with that this weekend.

Does itunes say its in DFU mode?

I 2nd Allan Hill's comment, I've been seeing this more and more lately, where the phone won't show the dfu symbol just a black screen. took me ages to work it out the first time. good luck

In addition to @brokegadget suggestion, you may try to turn your phone to DFU mode. I would suggest you to check & clean (using the right process) the connector pins.

Hope this helps,

Vincent
