HDMI no signal?

For a quick test, try hooking up one of your components directly to the HD20 and bypassing the Denon. If you still get drop outs then you probably want to look at the cable (again). If not then its something with the Denon and you may want to search the Receivers thread for a setting or F/W upgrade.

I found this link for you which has all the HDMI settings for your receiver...

I'd start with that and see what works. There is also an "official" thread for your receiver on these forums in the appropriate section.

I have a ESP200AU connected via HDMI to a Yamaha receiver via HDMI to a LG Blue Ray Player - all brand new.
All has been working fine since purchase 2 months ago (though the hdmi projector connection is quite touchy and loses signal easily).
We went to turn it on the other night, same as always and the projector display said no signal (usually when it does this we just fiddle with the hdmi and it comes back on - but this time, no good).
I have moved the BD and AVR so they are near the projector, tested a number of HDMI cables and lengths (all working fine in all different arrangements with my other tv) - still no signal with the proj.
If I plug the BD directly into the proj, the start up screen comes on, then when it should go to the main menu, it goes back to no signal.
Can't get my laptop display to go onto the proj at all - which I used to be able to do (directly or via AVR) – the same scenario works using my tv as the display.
The normal BD > AVR > Proj setup works fine with component cables. What could be the problem?

Also, the AC adaptor blew so I am waiting to see how I get a new one of those - I bought a 5 year warranty with the projector.
I was thinking it must be the hdmi ports somewhere but considering the proj comes on with the direct BD connection, I guess that not it. From the bit of research I've done, maybe a resolution issue??
Any help would be great.
Thanks, Amanda
