If you have a picture but it is green in all inputs, you have a bad Optical Block. This model series has been know for this problem. Retail cost of the part is around 800.00.
You would need to order it through Sony and or one of their authorize parts retailer. Although it is not the most difficult part to replace, it is not the easiest either and if you have doubts on your abilities have a professional do it.
I hope this helps.

Is there an adjustment screw for top screen?? My top screen is have issues with black. The screen is not always readable..Out of focus with kinda dark green instead of black. Already replaced it twice....


Hi,
The adjustment for the upper LCD is in the battery compartment, open it up, remove the battery. you will see 2 adjustment screw at the bottom, using a precision screw driver, turn it very slowly and don't push it.

Put back the battery, turn it on, adjust it again if you are not satisfied.
Hope that helps you!

Sony KP-51WS500: This TV comes on for a few seconds of picture and sound. Then the picture fades to green and then turns off within another 10 seconds. Is this a power supply problem? Or should I look in...


Adjust the Green screen drive,turn it down and see if that corrects the problem.
Remove the Front Bottom Panel on front of Tv and behind it will be the Screen/Focus Control block
It will have 3 controls on Top for Focus to each Tube R/G/B
and under them are the Screen drive controls for R/G/B.
But if adjusting the Green Screen Drive Control does not Fiox It ,then you have a Bad Green Tube.

Writing is green not black on top lcd


If the light on the lcd on the top is green and your text on the bottom is faded, get to the main ds menu (where the pictochat,ds download play, and the game.) and look on the bottom left, There you bwill find a sun shaped icon, touch this icon and it should contrast the light. (or the f4 fuse busted).

KP-51HW40 Sony 51" Fades to blue screen


The service manual on page 8 shows how to adjust the Red/Blue/Green screen voltages. To get to the adjustment board, take the front speaker grill off (two screws at the bottom left and right) and set it aside. No need to disconnect any wires. Then remove the plywood board with 4 screws that exposes the screen/focus adjustments. The top 3 adjustments are for focus, and you need not mess with these. The bottom 3 adjustments are for Red/Blue/Green screen voltage rough adjustments. My screen showed red lines, so I had to turn the bottom right adjustment with a philips head screwdriver just slightly until the red gun retrace lines where no longer visible.

Green Lines


NO CALLS NEEDED TO AN EXPERT. THEY WILL CHARGE YOU FOR LITTLE ADJUSTMENT YOU CAN DO YOURSELF.
READ THE WEBSITE BELOW AND MAKE ADJUSTMENT TO THE SCREEN VOLTAGES TO CLEAR SCREEN, BUT DO IT SLOWLY. IT SHOULD CLEAR THE PROBLEM.

Green horizontal lines across screen


try adjusting the green screen control. remove the front bottom panel of the tv by removing any screws holding it in place. gently pull of the front panel, there are gromets holding it in place, you will be able to gently remove the front, just make sure you get all those screws. now reove the small wodden or plastioc panel. now you will see the screen/focus assy. check to see of the screen controls are the top 3 or bottom 3. adjusted the center screen it's the green one, the other 2 are the red & blue. it is best to adjust in a dark room where the lines will show up easier. good luck
