Green screen


1.) Press and hold down the "Menu" key until the manufacturer's logo appears on the screen. This could take up to a minute or more. Release the "Menu" key when the logo appears.
2.) Immediately press the "9," "8," "7" and "6" keys in this order. Press the "Enter" button on the remote to enter the "Service Menu" screen.
3.) Press the "Menu" button to go to the second of the two "Service Menu" screens. Press down on the "Down" arrow until you highlight "Color Calibration." Press the "Enter" button to enter the "Color Calibration" screen.
4.) Select one of the color bars on the screen. Adjust the color by changing the values of the color bar by pressing left and right on the "left" and "right" arrows on the remote. Repeat this procedure with the other color bars as well. Stop adjusting the colors when the green cast is no longer present.
5.) Press and hold the "Power" button on the remote to exit the "Service Menu" and save the adjustments you have made.
Now turn the T.V. off. When you turn it back on it should reflect your personal preference.

Rainbow screen aiwa tv,, screen shows different colors like rainbow// brushing a magnet infront of the screen fixes the issue temporary


Picture tube is magnetized. Manual degausing is required. already you have done this.

Since you say it is reappearing, you have to check the following.

1. Relocate the TV or relocate if you have placed any tower speakers
or home theater speakers close-by.

2. Check whether auto degauss functioning OK. In the MENU
check whether you switched off auto degauss option. If it is OFF
enable it to ON.

3. Finally re orient the direction of your TV and watch the rainbow
effect. Switch OFF TV, wait for 20 mts, and again switch ON.
Repeat the process. It should disappear.

Magnetic toys or any other devises using magnet will cause this problem.

Different color vertical lines on screen Sony KDF-E55A20


Go to the last page of troubleshooting in the manual and perform the system reset procedure. Basically hold the Wega "arrow up" as you manually switch the TV off. It will automatically switch back on and reset. I had only vertical colored lines on the screen, with audio but no response to any remote control functions. The rest worked perfectly.

Tv won't power up


Check the inverter if you do not know what a inverter is chances are you need to bring this into a shop and have this repaired as first the inverter goes then the lcd makes colorful rainbows this would be the first thing I would check.

Sony Trinitron Color Rainbow


Usually when a tv is dropped the phospher screen inside the picture tube will detatch making the rainbow color This cannot be fixed as it requires changing the picture tube. Only other thing is demagnatize it with a demagnitizing coil (used by tv techs) but not likely to fix it since it was dropped. You have a bad picture tube.
