Question about Sony KP-57HW40 57" Rear Projection Television
I have noticed it more lately that during dark screens or no source screen you can see a series of arched horizontal red lines spanning the entire screen left to right, top to bottom. This is also accompanied by red hue overall!! They are present all the time but only noticable in dark areas or dark screens.. help
I tried the solution that was posted for this problem and it worked!
Just remove the Low front panel by removing the two bottom screws that are covered by two screw covers, then remove the second panel (black) by removing the 4 screws then you'll notice a module with 6 adjustment knobs, get a small screw driver, and with the t.v. on, being carefull , and with somebody accross the room looking at the screen begin with the lower left knob and turn left very slowly and ask the person across the room to let you know if the screen is better or not, after this I had to adjust the green as well so, I adjusted the next knob over to the left. Do this adjustment carefully and try to remenber the original position of the knobs in case you have to go back.f
