Problem: due to dusty LCDs the light is not pass on equally. so you get a unequal color background in your image. your projector is just need service and service of LCDs and inside parts are a purely technical job.

Remove purple haze around edges


The set needs to be focussed and reconverged. The red and blue images combined make a magenta/purple image. Adding green makes it white. Depending on the type of TV, if it's a CRT projection TV then there's an electronic focus control for each of the three tubes as well as the mechanical adjustment of the optical lenses. Given the description, then I'd have a look at the electronic focus first. A sudden shift in focus suggests that something in that circuit has given out. This would cause the red and blue images to go soft enough to create a halo around objects on screen.

Purple haze tv screen


Purple color on screen denotes absence of green color. Check the vidieo output section circuit board for any loose solder terminals. Re-solder all the suspected solder terminals by applying a little more solder, without making any solder bridge short in between adjacent solder terminals. This board can be located at the neck of the picture tube, will diretly plugged on to it.

The camera took great pictures then all of a sudden the screen appears as a purple haze -- and the pictures come out as just a purple blurry haze. Adjusting brightness doesn't work. Yet, the shutt


If the LCD displays correctly on previous photos then the problem is more than likely a CCD or associated ribbon connector failure due to moisture/condensation or age/misuse. Good luck with finding a replacement part!

Screen hazzy and issue with blue convergence


bad convergence would cause show to look as if it was supposed to be a 3-d movie, if a bulb was going out then people would look purple blue -green,or some other off color, so likely the green bulb is going out from the color of the people you described.

1) Could be bad CRT ( picture tube )===no green==purple.

 2) Might be lack of green drive to CRT==bad transistor.

 Recommend analysis by technician--usually worth it if CRT ok.
