Question about Sony Grand WEGA KDP-57XBR2 57" Rear Projection Television
Thanks for the quick response. I really appreciate it.
I found the focus box and see that the 3 screen knobs are on top, but which color is which is not marked.
what color is on the left, the middle and the right.
Looks like the factory put a big white blob of something over each knob
That would really help for me to work on the adjustment.
They are marked "R", "G", "B" the "G" is in the middle. they are hard to see because it is imprinted in the molded plastic. also the words "screen" and "focus" are imprinted use a flashlight to see them. on most of these focus blocks the screen controls are the ones closest to the mounting screws. blue is to the right green in the middle and red to the left but not all of these are the same so check them before you turn them. the white blob is a type of glue to keep the posts from being turned and is a good referance point to get back to the same spot if you have gone too far with the adjustment.turn them carefully with a screw driver to brake the glue.then make your adjustment if this does not cure your problem you will need to replace the block have a tach do this ( critical white balance adjustment and picture tube voltages).
