Someone pressed 'a button' on the remote - now there is no yellow on the screen - yikes - lots of red and green! How do I fix this?

Go to the menu screen and look for picture options and then look for color or Hue on the menu, this will allow you to change the hue and correct the color balance. I have a Sony and there is a yellow button on mine and it changes the settings to what they call Cinama scene and when I press this it makes the picture darker and more yello. Mine is a Sony and yours may be different.

Toshiba Rear Projection TV picture color is now a greenish hue

Hi, I used to work in Best Buy and one of the key things about rear projection TVs and the reason they push those service plans on you is that the tubes/colors need to be calibrated each year. You can do this yourself by checking out the following website: 

If you are not able to adjust the convergence using the remote you will need to replace the convergence chips. 

Typical Symptoms

1) Convergence menu does not work for one or more colors.  
Such as: Red moves up,down, but left or right fails. 

2) Screen is bowed looking.

If you have one or more of the problems above you need to replace the convergence chips. You can get a kit and instructions from  

Hope this helps :)

Sony-kp51ws510 picture turns to a blue hue with flickering colors

hello there this is an easy fix unplug the tv and take the back of the set, once inside the set you will see 3 coloured bulbs and a big mirror in the back theses over time get dusty and dirty and if you smoke it can get really bad you simply just need to clean the bulbs and the mirror with computer screen wipes or some sort of window cleaner be sure not to get everything wet inside this should sort if for you nice and clear again!

Thanks For Using FixYa

Problem with color

Yes you have a problem in the red crt driver board. Most likely the driver transistor is failing. This is a component level repair, so if you have no experience with TV repair, play it safe and call in a trained tech to assist you in this matter. Good Luck

Sony kv-32hv600 picture problems

Problem 1. Color patches at lower corners. These are caused by magnetic sources close to the TV. Do you have any Speakers close to the sides of the TV? Are they Magnetically sheilded? No? Move them away from the TV. Problem should then resolve itself in a couple of days. Problem2. Screen Slumping. Most likely a problem with the Pin cushion correction ckts. Get a good technician to have look. cost should not be much. Under 100$ plus Technician fees.
