| If the current 50ma that means the VPH _PWR line shorted most of the cases,(you can check it easily wit multi meter) so all the components which use this voltage can be faulty.
Some times very easy to fund the faulty components when it is a capacitor, because its burning or damading itself.
My suggestion:
1. Look through the whole main board (with microscope) and if you fund a burned, broken capacitor just broke it down
2. Remove the U800 and give 4 volts to the output VPH _PWR with your powersuply, in this case the shorted components gonna heating up (be careful because it will be very hot) |
