1 Answer

Alignment I see 3 images of the picture with the 3 colors of the projection. I'm thinking its just some alignment issues but not sure, hoping that i just need replace a part other than dragging it out to a repair place. Thanks!

Re: Alignment

Did you mess with the alighnments?? I doubt that just an alighnment will help as they do tend to drift but all three tubes dont go out of alighnment unless something happens to the circuit. If your a technician then sure you can replace the convergence ics but if your not its not like replacing spark plugs in your car. Electronic repair is a trained trade. Its not something we can teach you overnight or even in a month. Im sorry but If you are not a tech you should and its highly advised that you do take the set to a pro to have rthis problem fixed as theres very high voltage in these sets that can hurt you very badly.. Good Luck

Blurry and colors are seperated red green white

if you are viewing from a projection tv, chances are you have to go thru the menu of the tv to 'picture tuning'. here it gives you different things that could be fixed. one to look for is 'lamp alignment'. It should show all the colors and lines with directions to bring them into focus. This should fix the blurriness and 3-d red/green/white separations. hope this helps you!

I have a 3 year old mitsubishi wd-52526 lcd projector tv that is starting to have some focus/image alignment issues - in general picture is a little out of focus and there are rainbows around things at the...

the differnt guns are out of alignment. Your tv has 3 lcd screens, a red, green and blue one what overlay to form the image. Sometimes they move slightly for what ever reason and that causes the rainbow and out of focus picture. Its something that a trained pro should do but is a cheap fix and won't set you back too much

3 images in different colors-42 in Sony projection

So this is a rear projection TV.

Chances are the tubes are out of alignment. When cleaning or anything never move the tubes as it will be hell to get em back properly.

In the back you can take off the rear panel and move the tubes to partially re-align the picture.

This is generally followed by a model specific procedure using the remote to bring up alignment grids to finalize the picture alignment.

The reason for the 3 colours in the picture are that the rear projection units use Red, Green and Blue tubes to create the one colour picture.

All in all... When I messed mine up it took about 2 hours to set it straight again.

Now I just have to fix my flashing screen problem and i'm set.
