I’ve got green blue and red plugs. I plug the green in and I get a crisp black and white picture.
If i add any combination of the blue and red plugs to the green (both, or just the blue, or just the red), I get a fuzzy picture with the colours predominantly pink and green.
If I unplug the green and plug in blue and red I don’t get any video.
Not sure how it happened, but it sounds like you’re trying to connect a component* video cable (from a component video output, presumably**) to a composite* video input. Look for a couple more jacks of that same type nearby and plug the extra cables into the matching colors.
Or switch to an HDMI cable, which has it all in one AND supports HD video.
No, I had to look up which is which.
** If it were the other type of output you’d be able to get a normal picture from one of those plugs
Check that the other end of the cables (cable box?) are still plugged in all the way.
All RCA cables are the same, the color of the plug just tells you where to put end. Try using the audio cables and one of the component plugs to plug in your video, switching it to the same match on the cable box end. Try each on the component plugs to see if one is broken. If no problem on the plug, it might be new TV time.
BTW, component is very capable of sending an HD signal. The tv might not be, of course. Even higher than HD (2Kish, not sure about 4K).
yeah, something along these lines. the TV is not receiving the Pb (B-Y) signal which is carried by the blue cable. It is receiving the Pr (R-Y) signal, which is why the image is pink and green.
The cables are the same. Try switching them. If you get the same colors then something is wrong either with the cable box or TV. If you get different colors, then the blue cable is damaged.
Also is it possible the cub did something else. Could he have made any adjustments?
If you have an HD set and an HD cable box this a great excuse to switch to an HDMI cable which will actually carry that hi-def signal to your hi-def tv (everything else is just standard-def). They’re relatively cheap typically running less than $20 depending on length (it’s a digital signal so there’s no benefit in the spendier ones).
And when are you ever likely to want to mess around with that mess back there again?
Trying different cables is a good idea. The green cable is apparently working because that carries luminance information and would be expected by itself to give you a B&W picture. So, just try each of the blue and then the red cable on the green input and make sure you get the same B&W picture. Chances are the Cub pulled the cables out by the wire instead of by the plug and may have damaged an internal connection inside the plug assembly on the blue or red cable.
A couple of small nitpicks re the above. All RCA cables are probably the same for purposes of this discussion, although cables intended for video are often better shielded and heavier. But some specialty RCA cables are not at all the same as the usual ones – for instance, the RCA cable intended for a subwoofer connection is optimized for very low frequencies and would be terrible for a video connection.
Also, while component video is technically capable of carrying HD, it doesn’t support the HDCP copy protection protocol so some devices may limit its resolution for legal reasons.
