Xperia SP Turn on issue

[spuser]

sometime when I turn on phone The backlight turns on but
the screen stays blank(black color). However, this does not appear to be a
Sleep of Death (SoD) issue as the Android OS is still running and
once the power button is pressed enough times, the screen will
wake. its happening dailly 3to4 times.
I hv latest update of sp.

Repair your phone with

Update Service (SUS)

PC Companion (PCC)

Bridge (for Mac)

Do both SUS and PCC update exactly in the same way, or is there any difference?

SUS its a lot simpler in my opinion
