Scaler board and cables - where to buy???

I get a blank screen that changes colors every few seconds: blue, then yellow, then red, etc. I can't bring up the menu to try and select an input source -- I was told $350 for the board itself (+labor)... Any idea where to buy at cheaper price? Thanks BobbyJ

OK, here is the breakdown on whet you are doing wrong.

Video 1 - Composite -
Video - Yellow
White - Audio In - Right
Red - Audio in - Left

Video 2 - Components - HD - RGB = Red, Green, Blue
Video -
Red - Red Colors
Green - Green Colors
Blue - Blue Colors
White - Audio In - Right
Red - Audio in - Left

Your GameCube will only work on Video 1, unless you buy an HD (Component cable). You will need to buy HD cables for your device connected to Video 1 to work on video 2. I will assume it is a DVD player. This is a high definition cable to produce a better picture. Let me know if you do not completely understand

In case of a problem or clarification or my solution was insufficient, don't hesitate to post me a reply.

If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

Lack of red color


The quickest thing to check will be the cable. Make sure that the cable is seated properly on both ends. (pull it out and reconnect it on the TV and on the source end as well.) What happens if you wiggle the cable or bend the wire just near the connector end? If the screen flickers or appears better when you do this, you should obviously replace the cable. (HDMI, Component, etc..)

If that does not work then the next thing to check will be the female connectors themselves within the TV/source housing - I've seen many DVD players have poor solder joints so that repeated pulling of a cable or other torque causes an internal connection to go bad. Does this happen with all sources (DVD, CABLE, SAT, etc?) You should first check the cable that connects directly to the TV.

Red color appears missing from display


Push your red component cable firmly in the tv and the cablebox and you will be good to go.
