    same exact problem. This happened to me TWICE. there is a different contrast in color. It fixed by itself when i pressed "system off," however I doubt that has something to do with it. Maybe the video card is faulty I have no clue. I also highly doubt u have to change the contrast and brightness, etc. The problem goes away then comes back again on the lower left hand corner. Its a little blob of yellow-blue contrast.

Blothes of color in center and right side of screen. Very noticable when it's a light background.


May have burned CRT(s), (if you are not talking about convergence.) Burned CRT shows when that CRT (R,G,orB), does not show in an area of the screen where it should. Check bright white color = full R, G, and B CRT brightness. Gray = mid RGB brightness. Yellow = R+G(no B), Blue-green = B+G, no R, etc.

My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?


It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.
