Hi, thanks for the reply.
I'm more than sure that my issue has nothing to do with resolution of the hdmi output.
This is because I have two Dm800se, and one has this problem and the other not. Just to be sure I have flashed a clean OpenATV 5.1 in both of them. On both of then I can see the bootlogo just aftew switching it on. I can see on the tv screen the setting options (Video output setup i.e. scart or Hdmi, etc. etc.) on the Dm800se
that is ok at the end the booting process, while on the other one I can see the bootlogo on the tv screean when I switch it on, but as soon as the The linux kernel is booting the screen goes away and I got "no HDMI signal" on the tv screen. At the end of the booting process I can see the setup menu on the dm800se display but nothing on the TV.
I do not know how the hdmi signal out of the cpu is handled, but it is strange that i can see the logo at beginning of the boot and nothing after. If it is a cable issue or a Cpu issue I should not see anything since the beginning.
Something happens between the bootlogo display and the kernel linux booting that switches the hdmi off.
Should I try by replacing the TVS diods ? What else could be ? How to debug it ?
