Color is bad. Yellow green tint and at times is

Hi:
You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

chevyss555,

It sounds like you have a bad optical engine. I have a tip at

HI Bernard,

This sounds to me like the video lead is loose. Could you please try the video lead each end and tighten the locking screws if possible.

Regards

Nick

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

Hopefully someone on here has a manual and can tell you exactly where the tint controls are. Also need to try adjusting the color level, turn it clear down so you have a black and white picture.
Is the picture still green over the screen with the color control
set clear down to black and white? If it does, you might
have an issue with the green gun going out or problem in the
circuitry to it.


By the way, the best way to adjust the picture settings on a
tv are to first turn the color control clear down, then adjust
brightness and contrast for best black and white picture, then
bring up the color level to where it should be and adjust the
tint for best red/green ratio.

Turn down your color and see if the screen has a normal black & white screen. If it doesn't then the CRT is bad (picture tube). If it is black & White then you have a either lost your red or blue.That problem will be in your video driver circuit of which a service center can handle.

I have a blue-ish yellow ghost tint which just appeared on my 51" 51SWX20B made July 2002. Did the magic focus got a number 5 at the end. Did you get a number when you did the magic focus?
