Yellow tv screen

My tv screen is yellow, months ago it started as a patch of yellow on the left side, now basically the whole screen is yellow, i was told it is dust, i also was told this panasonic tv you just cant take the tv to a repair man and just blow the dust out.i was told it would cost me at least $600 or more to get the dust out.

    I have a Sony XA21M80 and my color keeps changing from normal to having more yellow or brighter. It flashes back and forth in no regular pattern. It keeps changing as per the picture. If background in scene is bright then it appears bright. If background dull then suddenly it changes to yellowish. The subtitle colors keep changing from “bright white” to “yellowish white” as per scene.

    Yes, except this has just started so it has not moved to cover the whole screen.

I have the same problem. I had to take the whole thing apart and found that the red filter has a burn pattern in it. I am still trying to find a red filter for it.

My screen has patches of yellow in it, do you know what could be causing this problem


this is due to dust buildup in light engine. you can replace it simply enough, comes out of the back. have to remove a couple of wire harnesses and a dvi cable that plugs into digital board on the left side. it's too complicated to repair for the novice.

I replaced the main lamp 6 months ago. Now I have blue on the right, yellow in the middle and normal color on the left. I also have a ghost image of tree branches on the whole screen.


Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine.

Blue haze and dull yellow patches on screen


The light engine in your set has gone belly up. It is a very expensive repair. Good news is that on a whole bunch of models like yours Sony has extended the waranty on the light engine. Check with a local authorized Sony service center and give them the model & serial number and you might get a free ride. If I were a betting man I'd take odds on 'you're in luck'. LOL
