There are actually 3 projectors inside, each handling one of those three colors which, together, make all the other colors. This is called "out of register" where they are aiming slightly differently. These need to be adjusted.

1st option is also right go for solution.
2nd is Patch sensor, laser dirt, hvt, or ITB unit..

a bulb can cause a short, particulary the tail bulb

next
unplug all the indicators, tail light assembly, headlight assembly,gauge assembly,and the switch blocks, and see if the short is still there, then plug them back in one by one, to try and isolate it.
The short is sometimes, an internal problem in the switch block, or can be the wires inside the plastic loom often around the steer head.

The wires are mostly color coded, if any are plugged into a different color, chase them through, may pay to make some notes as you dissconnect.

Hi there
I beleave it is to perform the manual color registration adjustment.

Press Menu. Then scroll to Maintenance and press Enter. Scroll to Color Regist and press Enter. Scroll to Color Regist Auto Adjust and then press Enter to Auto adjust.

But you may have to do this manully adjust all till get right,

Sorry cant help you any more than this.
All the best Pineworks

Clean or repalce sensor belt responsible for the wrong color register.

You can try to reseat the color PCU, but you may have to replace it. Also, make sure all of your color toners are seated properly.

You must go into service mode and re-align the registers, if you've never done this you must call a qualified svc center. Most color wheel replacements require re-alignment. The DLP must match the speed of the color wheel.
