Mac Mini no red in monitor, not monitor issue

I'm not sure if this is a hardware or software issue, but we've had our Mac Mini hooked up to our TV for about a year with no issues. The TV color is just fine on cable and DVD mode, but has no red when displaying from the Mac Mini.

What we've tried so far:

checked the cord tightness connection (couldn't find a spare to try)

calibrated color under system preferences/display

restarted, checked for updates

added a new account

Any ideas? Could the mini be going on the fritz?

First thing to try would be to reset the PRAM and NVRAM guide below...

Resetting your Mac's PRAM and NVRAM

Hope this helps

I would suspect the adapter/cable first if it's VGA, DVI, HDMI or displayport.

Try another adapter/cable.

Thank you for your help!

We tried resetting the PRAM and NVRAM, which was easier since we didn't have an extra cable readily available. Resetting didn't work, but we did finally find another cable, and it did turn out to be that. Kind of weird that a cable would transmit everything clearly, just leaving out the red, go figure!

Actually that not as unusual as it would seem. All it takes really is a minor problem in the cable to throw things off.
