Hi there, I was given a Runco flat screen TV recently that worked when it was taken down from the wall. It was being used with a universal remote, and I was given the original remote that just works the TV. Got it all hooked up and plugged in, the only indicator that there is power to it is a little red light at the bottom left of the tv frame. I changed the batteries in the remote and pushed the power button and nothing...I do have it hooked to our cable box and it is turned on and our other TV is working from it fine. A TV tech made me some special fittings for the green, blue, red, black and white wires that have to be plugged in since the TV is so old my cables had the wrong fittings. Those are confirmed in the right place, so I don't know what else to try. The manufacture date is 2004, model # CW50MC. Any thoughts, or options to try are greatly appreciated.
Thanks,

I'm not familiar with your brand / model but I also have an older commercial-grade plasma (Panasonic). I quickly searched for a manual for your model and found
http://www.manualslib.com/manual/142870/Runco-Cw-50mc.html?page=13#manual . You should look thru that and see if it seems to match your model year.
A couple of quick thoughts (beyond asking the donor for advice):
1. Where are the green, blue, red, black and white wires plugged into? It sounds like a 5-RCA RGB cable (i.e. 5 separate plugs at the end of the cable) but the linked manual only shows a "mini D-sub 15-pin" RGB input (i.e. a single rectangular plug with 15-small pins within) on your display. See input #4 on
http://www.manualslib.com/manual/142870/Runco-Cw-50mc.html?page=9#manual . You do have a separate component input but that only needs the 3 blue, green & blue plugs.
2. If you are using the 15-pin plug, make sure it is input into the "in" port not the "out" port (i.e. input 4 vs. input 5 on the above linked page).
3. If you are using an RGB input, you need to make sure the display is set to use it as a HD component video source vs. a computer RGB source. If you are using a remote similar to that shown on
http://www.manualslib.com/manual/142870/Runco-Cw-50mc.html?page=13#manual , you should be able to toggle the button labeled "PC/HDTV-1" to switch back and forth. Normally, an incorrect setting will still yield a picture but it will have a green tint. This setting can also be changed within the menu as discussed in the manual.
4. I think that your display's 3-RCA component input is limited to 480p sources. Thus, you probably do need to either use the mini D-sub 15-pin input (set internally to HDTV component vs. RGB PC) or the separate DVI input. Your cable box likely has either component out or HDMI out. You would use either a 3-RCA component-to-mini D-sub 15 pin cable or a HDMI-to-DVI cable. I use the former with my old plasma and my satellite box. These type cables can be purchased from monoprice.com
5. The red light at the bottom left indicates StandBy mode. A neighboring green light should come on when you hit the power button on your remote.
6. Even if my connection is bad between my source (satellite box) and my plasma display, my particular display will show "No Input Signal" on the screen. Are you not seeing anything at all? You might try to hook up a basic "composite" video connection just to make sure your display is still working. Find the yellow RCA-type video out from your cable box and connect it to the composite video input on your display as shown on
http://www.manualslib.com/manual/142870/Runco-Cw-50mc.html?page=11#manual . Note that the neighboring button may need to be toggled to "Composite" from "S-Video" (can also be done with the remote).
7. Sometimes these commercial displays use "BNC" vs. RCA-type connections. If so, you might need to get a few RCA-to-BNC type adapters at a local Radio Shack.
I hope I haven't overly complicated things for you and that your issue is very simple to resolve. These old commercial displays are extremely well made but they are a bit quirky.
