Have 2 units that suddenly just stopped working. Started with randomly not powering up. Turned it off and then on again and then it started...but more and more often it hanged and did not power up after shutting it down. and now it does not power up at all. The power supply is ok but the unit will not start. Have not changed any images or booloaders, just used it.

Anybody with this failure? Schematics over the hardware or service manual would be really nice if it is available.

Donīt want to start HW troubleshooting before asking here and receiving any documentation. Think more people have the same issues that the HW just stops working without any reason.

Thanks in advance...
