Hi!
If SB made the same mistake too and used a wrong power supply.
I repaired the mainboard by myself. The defect parts were:
- 2 x CS5340 ADCs Chips
- 3 x CS4270 Sound / ADC Chips
- 1 x TPA6111A2 Phones Amplifier chip
The chips are still available in electronic stores. Luckily no other parts where damaged, since they are powered by 3.3V over voltage regulators.
I got the schematic from the support team.
best regards, Robert
