Question about Hitachi PJTX100 Multimedia Projector

1 Answer

No input detected on projector


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.

PJ-TX300 suddenly not detecting HDMI input

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?

I changed my desktop background and now my projector will not display

I would start by cycling this through the f4 option again first. Next I would connect the projector to the computer and then booting up the computer. Next I would disconnect the projector...turn it off, connect the projector again and then power up the projector. Try every combination of sequencing to get the computer and projector to talk to each other. It would not be a bad idea to change out the cable and try a new one as well. If it is a ceiling mounted projector then connect straight to the projector and try that.

Hitachi cp-x300 will not go into advanced mode

I don't know that model but normally mirrored (ceiling) settings are in the basic menu. Some of the hitachi models won't go to Advanced mode or some of the image settings unless there is a signal that they are adjusting as you end up with settings for the RGB input and separate settings for composite (video via phono)

I see no red and green colors on screen projected by pjtx 100, the rest of the colors are visible.

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.

What size are the mounting screws?

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.
