@dazexy

If you try to reflow MMCC module, you have a very big chance of getting "black" display. Reflow of this coponent rarely work in my exsperince. Lately I've fixed like 8 sets with this fault. It's more or less the same problem known in 6210 -> COBBA where the pads gets oxidized.

Only way to fix this fault properly is the remove MMCC module, fix the pads on PCB, and then reball or even better chnage the MMCC module. Radio calibration not nessesary !!
