My father bought a new Samsung LED, so I told him to give me his old 29" Sony Trinitron, it's a KV-X2903E and has a RGB input, and front AV connectors, here it is with my SNES plugged in:
It's a bad pic, but you get the idea, I will try to make better pics later, also I don't know how to calibrate a CRT TV so the colors are not perfect
You can calibrate any machine just need a colorimeter and linux/windows to use the programs that can test a display color values. You can always go look for an avia calibration disc and take it from there.
The first method is the best way since it can account for the tv exact values and any external lighting influences.
