Hey guys, i'm new to the forums here, and I need some help/advice.
i recently bought a house, and had to set up my new theater room.
basically it consists of the following:
102" 16x9 screen
Mitsubishi HC1500 projector
Onkyo Receiver
Psyclone source selector
xbox 360
xbox (modded)
Wii
playstation 2
samsung up-converting DVD player
dreamcast
the DVD player connects via component to the receiver
the xbox, 360, ps2, and wii, all connect to the psyclone source selector via component video, when then connects to the receiver via component.
the dreamcast connects to the receiver via S-video
I have 30foot Composite, S-Video, and Component video cables that run from the receiver to the projector. instead of buying component and composite video cables, i bought two sets of stereo audio cables and marked them with colored tape to use for the component/composite video. anyway, it seems that whenever i view a 480i or 480p source over the component input, i have diagonal lines through the picture. they are sometimes more noticeable than others. they seem to be worse on 480p than 480i. over the svideo, the problem goes away. also anything at 720p, 1080i, or 1080p all look just fine.
i had everything set up exactly the same at my old house and never noticed this problem. the only thing different is the installation. at the old house, my theater was in the basement with no ceiling, so i could run the wires however i wanted, and they were spaced apart a little. now all of the cables run through a piece of conduit.
i have tried several things to eliminate the problem, but i cannot seem to make it go away. due to the layout of the new house, i had to run power to the projector through the conduit as well, using an extension cord. that was my first suspect. so i unplugged the power cord from the wall, and ran a separate extension cord from a different outlet, but still the problem persisted. i tried bypassing the psyclone source selector, but that made no difference. i tried bypassing the receiver, but that still made no difference. i havent done it yet, but i am planning on taking one of the components back and connecting it directly to the projector to see what that does, but i suspect the problem is with the cables. they are nice cables, but like i said earlier, they are audio cables...should that make any kind of difference?
due to the way the house is constructed, and my limited handyman skills, running the cables through the conduit seems like the only option. is there anything i can do to make this go away? most of the stuff i view is in HD, so it isn't that big of a deal, but occasionally i like to play the Wii, or a game on my old xbox, which only run at 480p max. especially when people come to visit, they like to play the Wii...and when it looks like crap, it really detracts from the wow factor of having a 102" screen in my living room.
i have read some places online where people have made their own video cables using rg6 coax cable and crimp on RCA connectors. i saw that home depot has this stuff in stock and isn't too expensive... that cable would probably be better sheilded than my audio cables, right? do you think that would help? i don't know what else to try....i don't have alot of money to put into this right now, we are expecting a baby in a few weeks, and we just bought new windows for the house..
any suggestions would be most welcome.
thank you..
EDIT: in my original post, i had not yet hooked any component directly to the projector bypassing the 30ft cables, since then i hooked up my Wii directly to the projector via it's component video cables, and there were no wavy lines. so it appears as if it is definitely the long cables. |
