How do i know which colors need to be replaced

If you are replacing the sensor with a part from an auto parts store, the brand of part has a conversion chart in the box. If you need the factory colors I need to know which sensor.

you connect it to your computer , I mean software , you can determine which ink needs to be change it

Could the message have been "Replace color PCU (Type A)"? In that case, you need to replace all three color photoconductor units (order Printer Maintenance Kit Type 7100A).

I do not know of any Replace CPU error messages. I hope this helps.

Unless some one has replaced the wires in the harness everything is color coded blk to blk,green to green,brown to brown etc.

When you go to the paint store, they look up the vin and that number has the paint number in it. They know what it is and how much you need, just bring your check book. You might find the code on the door post, it usually has all that info. Hope this helps. Oh yeah, the rattle can has GM colors too, You could check them out.

black is usually power and if there is a blue its the feedback to the pcm

sounds like the color wheel needs to be replaced very easy repair on that model Samsung.

If the color wheel doesn't start rotating or get up to the proper roatation speed then the lamp will never fire.
