I've said this many times before on this forum, test all your equipment with short cables (2m or less). Set up your system like you normally would just using short cables. I know it can be a pain to temporarily move the projector close to the components but could save a lot of time. If it works with short cables and not long ones the problem is the cable, period!
It doesn't matter if some devices work with that cable and others don't. You have a signaling problem. HDMI has a small amount of variance in its specs and it is very easy for one device to be more tolerant of an out of spec signal than another.
It would be prudent to use a device as mentioned before to bring the signal back into spec or use another solution for long HDMI runs such as a fibre optic or Cat5 baluns.
If the system doesn't work with short cables, then it is time to start swapping components to find the problem piece. It could be a bad short cable but that is less common.
Hope this helps.
Thank you everyone for your replies so far... this saga isn't over yet. I will post my progress.
BobL I took your advice and unmounted the projector and brought it closer to the other components. I tried my 20 foot monoprice HDMI cable (xbox to receiver via HDMI and then receiver to projector via 20 ft HDMI) and it works!
You were right! Going from 20ft HDMI cable to 30ft HDMI cable has killed the signal.
So based on what you and other were saying my options now are:
1) keep the 30 foot cable and purchase a signal booster -- I have to learn/read about these
2) "fibre optic or Cat5 baluns" <-- BobL suggested this, can you explain these solutions with my current setup? Are these just two additional cables that I can use instead of my HDMI cable but terminate with HDMI terminators?
furthermore, is this the Spectrum website?http://www.spectrumelectronicsolutions.com/
<-- pretty old school looking, they are based in FLA, I am in Vancouver, Canada
What's the Ethereal website? Is this the place you are referring to?http://www.etherealhometheater.com/
can you suggest actual boosters? (model #'s) that you have had good experience with that would work with my setup? thanks a tonne!
which solution is best? all of this is new to me and over my head... please assist/educate
Merry Xmas everyone!
