Hooked up to projector and cable box with HDMI.flashing video.

Have you tried a new HDMI cable?

Is your TV connected to a Set Top Box (Cable TV box?).
If so, then you will get blank screen until that box is powered on. Secondly, you could check the cable (usually HDMI cable) between the SetTop Box and the TV..

both should be hooked directly to tv

VCR side of combo should be hooked up with composite video(yellow, red, white wires) to video 1 input

DVD side of combo should be hooked up component video (red, blue, green wires and red white for sound)

cable box should be hooked up HDMI or component to TV if HD or composite video if SD

hope this helps

good luck

Is the projector receiving a source signal? if not it will power itself down after whatever time you have it set to do so when no signal is present.
Just an idea?

You need to Bypass the Receivers HDMI port and use HDMI directly to the TV. Your receiver has HDMI version 1.2a and is not 100% effective. Use the optical out from your Xbox to the receiver and all will be well. 1.2a has issues in every receiver on the market. Supposedly 1.3b on the "new" receivers has fixed this issue. Hope this helps

i think its your cable box. check it carefully.

it does do dvi-d for computer, but does not handle high-definition video. it does not have the same resolution.

Change the video out settings from your system

Your Lcd Projector Lamp/DLP Television Lamp went out

its about $165-$200 to replace if not under warranty

Check the couplings at either end of the cable. Sometimes these will loosen and can cause a lack of signal strength.

but its probably not the cable, its probably the ps3. HDMI cables don't really break because they are just wires, they don't have moving parts. Try connecting your PS3 to your TV with the regular cable red, white, and yellow connectors that you got when you bough the PS3. If the PS3 doesn't work with the original red, white, and yellow connectors then you know its the PS3. If the PS3 does work fine, you know its either the HDMI cable (still unlikely) or the HDMI connection on your TV or PS3 (more likely
