Lg flatron w1943tb color fades in and out to a blue green

LG Flatron L1515S doesn't need a driver to be installed on Windows Computer or any other systems. If you have problem with it, then it should be your graphics driver that you would need to install.
Similarly W1943TB-PF doesn't need driver. (I am not sure which one among the two LG Flatrons you have since your question is tagged under the LG Flatron L1515S while your problem refers to LG Flatron W1943TB.
If you have other problem, let me know with more details.
Good Luck.
Thanks for using FixYa.

problem with the monitor Display cable. it is damaged.

Normally monitor will receive 3 colors red, green, Blue signals from CPU. If one cable i.e Red wire connection is missing in display cable which is connected to monitor, Red color image on monitor wil be replaced with other fade color.
So, need the replace the display cable or display connector!

Light Engine is Bad, If you had said TV was making loud whistling sound then it would be Bad color Wheel

hi verifies if you are connecting good the video cable i mean the red, the yellow, and the white, if this dont serve you, is because your tv is to old.

replace the colorwheel.

The fix for this is here somewhere, as I had the same problem last January and the solution was posted here in March last year. I'll try to find it and post the link to it for you, later.

i have the same problem with my sony trinton tv 36 inch if you know how to fix this please email me on [email protected]

If the picture is dark or messed up too bad, the magic focus will not function, are all the primary colors faded? RED GREEN BLUE? You might have a bad CRT, would call a service man to check out.
