What connections do i use to connect projector to tv?


You don't connect a projector to a TV.

A TV doesn't have the capability of supplying a source signal to another device. It can only accept a signal and display it itself. Connect a DVD player/Blu-ray player/TV receiver/Games Console to the projector directly via the AV sockets.

Use a separate sound system if you need more volume than the projector's tiny built-in speaker can provide.

The SP7205 will only show 480P. I have connected a DVD to the 7205 via composite cables however the unit only shows 480p. How can I get 720p or 1080i?


Unfortunately the highest video signal you'll receive through composite is 480p. To achieve anything higher than the said signal, you'll need to utilize either the component or DVI input of the projector. Those inputs will detect any HD signals.

Also if you've not done so already, you'll need to check the settings of your DVD player to make sure that it's outputting 720p and/or 1080i/p signal. Hope this helps you out.

I have a canon projector with a blue ray dvd player. I connected the video signal using a HDMI-DVI cable, but I cannot get the video signal, how do I set it up?, is it compatible


It's possible that the BD player's HDMI output is either not enabled (look in the player's manual for instructions)
Or the BD's output is set to 1080p which this projector will not support. This projector's maximum resolution
that it can support (down convert) is 1080i The i means interlaced and the p means progressive. Set the BD player's output resolution no higher than 1080i and it will probably wok out for you.

Projector signal goes bad after 25 minutes


It appears the projector was over heating. Why it affected the DVD signal and not the computer signal, I do not know. The other confusing thing was the projector was hanging off the ceiling and should have had plenty of circulation. When I climbed up to check for excessive dust, I found that the lens cap had been placed over the intake vent. I blew off the dust and removed the cap. After running the projector for an hour, it appears that the problem has been solved.

My Toshiba TDP-ET20U Multimedia DVD Projector will not play a DVD. I can hear it reading and reading it, but it will not play. The same DVD will play immediately on another DVD player.


Hi jennydority

Have you tried cleaning the DVD player's lens with a CD/DVD cleaning disc yet ?

Give it a go , it normally solves the problem.

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.
