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.

When I connect to the DVD player with a scart connection at the back of the DVD player and the S-Video input on the projector I only get an hour glass symbol on the screen and this gets locked in. Is there...


Is the DVD player producing S Video? If not the projector will not work.
Has the projector got a composite video input? if it has try that instead from the DVD player.
Hope that helps.

No sound coming to the speakers.


What is the model number of your receiver?
Many receivers don't support audio over HDMI, they just switch the signal from hdmi-in 1-4 to hdmi-out, but can't analyze the data to take audio out of it. Your receiver is probably one of those.
You need to connect the DVD player also via spdif digital cable. Look at the player to see if it has optical (square black plug) or coax (orange RCA plug) connector. Receiver probably has both of them.

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.

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.
