DM 800HDse not starting. Black display - 12/12/16 08:44 PM

Hi all,

my Dreambox DM800HDSe was running smouthly with the July update without any issue. Since some days, my dreambox is not booting. Everything is black. I have attached some pictures. Maybe you can help me or give me some good tips what could be the issue?
thank you very much

No leds active on the motherboard, only the tuner led.

1. Try it with another power supply that is 12vdc and at least 3amps.
But beware of the polarization, the center must be the plus side.

2. If that not have helped, check the dc voltages if they are present.
Dm800se fault-finding, vdc measurements

For more info, see my dm800se topic,
Dm800se, Schematic drawings, Pcb images etc..

Hi Jonny_B,

thank you for the reply. It appears that the cable was dmged. I changed the power cable and it is running again :-)

Hi Lamps..

Ah, so actually a power supply problem.
Glad you got it working again, and thank you for your message.
