iPhone 6 backlight faint after drop

I got myself this iphone for a bit of training on the backlight related problems. Iphone was dropped badly with upper portion of screen smashed. I removed the shield and nothing seems visually out of order. Connector seems in order too.

With phone turned off I'm getting a steady 4.2V all along the line up to the filter and pin2. When phone is turned on, at filter TP I get a steady 14,7V wich seems a bit too much on the low side and might explain the low backlight. Should I turn my attention to U1503 and try replacing it or there are other possible components to be checked and I'm missing right now ?

Do like jessa does on ipad rehab and change all the backlight circuitry good practice :)

Check another screen, maybe the leds in your one are damaged... failing that check the filters, diode, controller and coil like they say it's never the coil but it can be if it's lost some of its turns or is broken inside etc...

I have had some bad screens that are just a little dim and have a blueish tinge to the backlight
