You should first turn off all the color on the set, or play a b&w Tape or dvd. What were looking for here is, what the color balance or grey scale looks like first. If a B&w video or whatever looks true to grey and black and white then you have whats called croma problem in the color or video demodulator. My friend I wish there was an easy way to assist you in this type of repair but theres not, as it could be a problem in the video/croma demod section of the video jungle IC and this is not a user serviceable part or repair as thers several issues concerning Hi voltage as well as x ray radiation. Now if its a problem where the grey scale or the B&W is not true to color then theres a problem in the R G B driver circuits. Could be a simple drive adjustment or even a soft or weak picture tube. I hope if your not a tech you seek a pro to assist you in this troubleshooting as this could be dangerous for you as there are no user serviceable parts inside this set. Good Luck

Trying to fit G202 electronic ignition to G11 Charade. The G202 coil has blue/brown wire and black/blue. G202 distributor has black/brown wire and black. Can you tell me where these wires should go?

The colour coded wires seem to differ at randomn. To identify the cables:

Dizzy:- use a multimeter set on ohms.. When you measure about 3 meg ohms, your red probe is on the +ve wire and the black probe is the signal to the coil.

For the coil, it hard to measure the primary resistance so the general convemtion is looking at the pins on the coil with the taper at the top, the +ve is on the right and the signal (coil -ve) is on the left. Sometimes you'll notice one of the wires on the coil is a thicker gauge, which is generally the +ve.

Red colour prints brown

Just replace the non genuine inks with proper Canon ones and then do about 4 full cleans, that should fix it. If not you will have to replace the printhead, which is usually caused by using non genuine ink. Good luck
