This was the first thing what i want to replace. I have ordered revision PCB50b and will use this part for a test.

hi Ezo, thanks for your feedback. Teh H/W Test said "Hardware error: Check connections" The VPP LED is on, the VCC only a little bit. I have tested the usb power and ac adapter. Same problem.
