(1) Check
U1201 (ISP)
PU9509, PU8202
for any short circuits.
(2) Demount the shielding and compare the impedance of the pins in the table
below with normal PCB. Besides, connect the display and camera to probe
the voltage and swap the corresponding IC of the voltage shown in the table.
(3) Remount or change the
