HDMI failure

Hi!
Suddenly, we have no picture from the HDMI connector on our DM 800HDse. Scart connector works without problems.
Have reinstalled BH 1.4 but HDMI is still not working. Scart works. Any idea?

Sorry to say but from my experiences..

50% A cpu failure, mostly only to repair with a new cpu.
35% Related to the cpu, but then a print track or bad solder track from the cpu.
10% Hdmi cable, or issue with the tv hdmi connector.
2% Software related.
1% One of the diodes, D600/D601/D602
1% Hdmi connector failure.
1% Other unknown cause.

But mostly it is the cpu, and mostly fixed after a new cpu.
For more information, see this topic for a schematic.

Ok, thanks for the info. could have been worse. Box still works with a scart cable.
