Question about Sony KP-53V75 53" Rear Projection Television
Starts out with a bunch of green faint lines that go across the tv after alittle while whole screen goes green still have sound and all any solutions or possible estimate on cost to fix?
Behind the front grille there is a wooden panel remove it and yo will see a small black epoxy box with 6 knobs sticking out from it.
with the color turned down all the way, look closely for r,g,b on the box beside each knob this denotes which knob is for which color.
you need to adjust the 1 marked g on the bottom row. this adjusts the green bias to the green tube. this will get rid off the whiteish lines. adjust this knob counterclockwise in a darkened room untill the color shows a black and white picture. adjust slowly as the set will be monitoring what you are doing and will adjust itself as you adjust. bring the green down just enough so you don't see anything, make sure that you don't see red or blue either, if you do also adjust untill you don't see any color. these adjustments should be done with the input set to a video input that has no signal coming in the set will show the input label and nothing else.
when you have the raster( screen ) all dark you can go to an input with a signal and make sure the image is black and white adjust the bias of the color that is too much so that it is black and white.
hope this makes sense to you. now turn the user color control back to where you want it.you are done. reassemble, enjoy
you might have to do this again in a few months as the control you have adjusted are dirty and can't be cleaned with a cleaner.
moving these controls cleans them but the color balance procedure would have to be completed after such movement of these contols and any quick movement would have to be done with the set turned off. a quick back and forth movement will do a better job cleaning the tracks inside that adjustmet block but will mean you will need to do the setup adjustment all over again in order to get the screen blank and the color to balance to black and white. the top 3 knobs are for focus of the individual colos only adjust if the red, green or blue isn't sharp, you can try these to see with out doing harm. finally if thebias is too low then th lifgt on the front of the set might blink at you and the auto alignment might get part way through and stop. if this happens you need to bring the bias adjustment back up slightly. adjust only the bias for the tube that has too much color to start with and if this happens you will know that the bias control you just adjusted is the 1 that needs to be adjusted slightly.
