I have a problem I am hoping someone can help me with.
I have the following equipment...
Scientific Antlanta 8240HDC cable box
Samsumg 32" flat panel
XBox 360 (normally not in system but tried)
Monoprice HDMI extender (cat6 15')
When I originally bought everything it worked fine through the HDMI but when I moved to the new place the only way the HDMI input works on the Epson is with my HTPC.
I have tried the following...
Hooking up the PS3 and 8240HDC via component to the 3806 and letting it upconvert to HDMI= excellent picture via the Samsung, blank screen via Epson
Hooking up component straight to Epson= poor picture quality
Hooking up the PS3 straight to Samsung=excellent picture
Hooking up PS3 straight to the Epson with the same cable= blank screen
Hooking up 8240HDC straight to Samsung=excellent picture
Hooking up 8240HDC straight to Epson=blank screen
Hooking up XBox 360 direct to Epson=excellent picture
I have tried putting a switcher Monoprice MPSP08=Excellent picture from any source to Samsung (Xbox not tried) but only blank screen to Epson from all sources except PC (Xbox not tried)
Sounds like a "handshake" issue, which could be a loose connection, so reseat all of those connections, or you need to reinitiate the handshakes by powering off/on your components, sometimes in a particular order starting with your sources, working up to the Epson, or visa/versa.
I replaced all my cables with Monoprice Redmere cables and I got a new Denon 4520... The first time I fired it up everything worked. When I switched back to the input I started with no pic. I then switched to my other inputs and I lost them all. I also picked up a Monoprice HDMI amplifier and tried the whole setup again... Same scenario, everything worked until you switched away from a input and then switched back to it. I am thinking there is something wrong with the Epson projector. If I have the Samsung TV hooked up I never see the problem. I just can't afford to replace the projector at this time. :-(
