This works with the two other colors, blue and green also. Not all models of Sony Projection
TVs have the red, green, and blue pots in the same order as the picture that is listed on
this link, so you may want to google search for your model's service manual. The service
manual can also help you be able to remove the cover for your particular model of TV. I was
able to find the service manual for my model, and sure enough, the order of the pots are
reversed on mine, so I would have been adjusting the wrong color. Read all of the comments
on this link too, because you can find other helpful tips and may even find someone with the
same model of TV as you that gives more specific instructions for your model.

P.S. You can also clean the mirrors and dry dust while you're in there which can help with blurriness and focus. You may have to adjust all three colors to get the picture back.
