THose are G2 settings they have to be adjusted to certain voltages. You can ball park the adjustment by setting conrast, ad brightness levels to 50 percent. Shut color level to its lowest setting then adjust each screen control to achieve a good black and white picture not too bright. then turn your color and other controls back up. This should get it ball parked for you. Anything further and you would need the service manual. If you'd like a service manul let me know I have a link that has them at a cheap price and provides free support with them.

What causes the picture to have a green tint


there are 3 color cathode in your TV red,green,blue cathode.The red and blue cathode might not working in your set that is why you have a green screen. Open the back cover of your TV you can immediately see the 3 cathode lamp at the back. Clean the lamp first using a clean clothe. Power up you tv and see whether the 3 lamps are lit. If lamps do not light up,check the circuit board where this lamp is connected re-solder all the components in this lamp. There is also an individual screen adjustment for the lamps it is located at the front panel and labeled RGB screen...try this first and let me know how it goes..

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.

Converence


green is fixed so you have to move red and blue to green.
by using the remote you may find a simple converge function and open this and using arrow keys move the blue or red first to center of screen, repeat for other color you should see the lines moving toward a a white center point.

if the lines do not move with remote try manual ...menu on the set. if still no movement you have a problem on the convergence board and need a tech to fix.

A service manual will explain complex convergence to the detail .
but this might take hours to get it right.

Picture on big screen


Chances are, if it's an older set, componants have changed value through use over time, which also includes the picture tubes and associated driver circuits. The way to compensate for this color drift is through adjustments. Either turn the red down a little, or turn the blue and/or green UP. Be carefull though as there are potentially dangerous voltages in and around the circuit boards and picture tubes.

Bad color .


Turn the set on without an antenna, so there is only snow on the screen. Measure the 3 cathode voltages at the CRT, red green and blue. If the 3 voltages are about the same, around 175 volts, then the CRT is bad (purple picture means bad green gun). If the red and blue are around 175 and the green is over 200 volts, then there is a chassis problem, usually the video output transistor itself has gone bad or come loose.
