I have a hitachi pjtx-100 ceiling mounted projector that worked great when connected the following way: DVD Player>Component video cables>reciever>component video cables>projector.
I recently remodeled my house, and opted to run an hdmi cable instead of component video cables. Then I discovered that my projector does not have an HDMI input! -But it does have a DVI input. I thought the problem would be solved by buying a HDMI-DVI adapter. -No luck. The current configuration is: DVD>Component video cable>reciever>hdmi cable>hdmito DVI adapter>projector.
Maybe related- I bought a new Sony Reciever (STR DG 510) to take advantage of the HDMI output. Whenever I select "DVD" the message "unlock" appears on the display. There is now reference whatsoever to this message in any manual, so I can't get rid of it. Is the unit "locked, thus inhibiting the signal?
I'm pretty technically adept, and have gone through all of the motions of changing the input signal on the projector.
Also, the dvd player is about 5-6 years old...might the signal not make the transition from component video cable to hdmi? Thanks for your help!

Re: No input detected on projector
It sounds like the A/V reciever does not upconvert the component signal to HDMI. Not many do. The Marantz recievers will (SR6001, SR8001, etc..). Also bear in mind that HDMI cables are finicky and may require amplification over a few meters long.

I think that its a port issue, if all the other ports are working but hdmi is not then one of the pin on the circuit board may have come loose. I have the same issue. Could try to solder it back on or use a glue gun. let me know if this helps?
There might be several problems. As the projector has component only connections and the DVD player none, then if the Receiver has component out, you can hook it up to that. If the receiver has HDMI inputs then you can connect the DVD player via the HDMI socket to it. The Coax sockets on the DVD player will be for sound. Number one should be connected to Digital coax 1 and assigned for it.
It's possible that the sound on the DVD player is switched off on the coax or has the wrong format selected. You will need to see the player's menu for this, so if you can't see the screen using the projector, connect a TV instead.
However if the receiver has no component out and no HDMI sockets you will have real problems connecting the DVD and using the projector with it. Though you should be able to hear the sound via the Denon.
If you are using a component video cable (Red, Green, Blue) you may simply be missing the Red cable. It may not be fully plugged in.
You can verify that this is the case by:
1. Unplugging all video cables
2. Plug in the green cable, you should see a black and white image.
3. Plug in the blue cable, you should see some colours coming through.
4. Plug in the red cable, you should see all colours properly.
If not, unplug the blue and red cables and plug the blue cable into the red port. The colours will look incorrect, skin tones will be blue.
If the colour comes through the problem is the cable.
If the colour does not come through, the problem may be the projector.
The brass mounting holes on the bottom of Hitachi data projectors require a 4mm bolt.
Typicall 4mm x 10 is the shortest bolt I will use if when installing a projector on a ceiling mount, and 4mm x 20 will be the longest. I also recommend picking up 3 washers and spacers of varying sizes if you want to insure the projector is mounted level without warping whatever it is you are attaching it to.
BMS makes great locking mounts that come with all the mounting hardware you'd need to attach a projector to it.
hello i believe your problem is that you are trying to downconvert from hdmi to component connections and Denon receivers will not do that.
I have a 4310 and I know it will UPconvert from an analog signal to HDMI but won't do it the other way around.
you may have to use component inputs for all your equipment. You will also have to go into the receivers menu and designate which signal is being used for each component as it won't auto select between analog and digital signals when it comes to video.
