iPhone X touch not working ; missing caps and filters

Hello iFixit, I recently received an iPhone X for repair because it had no touch. I inspected the board under the microscope and found out that there are some missing filters and capacitors. As I do not have any donor boards for the caps and filters, I wanted to know is there any way to fix the no touch issue?

The filters and caps missing are :

C5809 (SPI_AP_TO_RACER_MOSI_CONN) ;

FL5891 (PP5V25_TOUCH_VDDH) ;

C5807 (SPI_AP_TO_RACER_SCLK_CONN) ;

FL5860 (HALL2_TO_AOP_IRQ_CONN_L) ;

C5842 (PMU_TO_TOUCH_CLK32K_RESET_CONN_L)

Any help, would be highly appreciated! :)

Update (11/05/2020)

Thanks in advance!

You will at least need to replace the filters. Even after replacing the filters you still might not have touch.

How did they become removed to start with?

I would start by checking the touch connector and filter pads for proper diode readings. I would suspect an open line on one of the circuits which will require you to separate the board.

I suspect the previous technician might have somehow gotten the filters to be fallen, i guess he was using a hot air gun to separate the board that might have caused the filters to fall off.

I checked the touch connector where I am getting improper diode reading and the filter pads as well have improper readings.

@iammyron07 Next step would be to separate the board and check the pads on the other side.

@imicrosoldering Just checked, the pads on both the layers seem fine to me, No ripped pads as such. Really confused with this one.

@iammyron07 Take some readings of the corresponding pads on the top layer. This could be a heated CPU.
