Mitsubish WD 65638 fuzzy/blurry


is the menu coming up the same. as it can tell you a lot if it is not. fuzzy screen in the middle could be the mirror has come away from the back or there is a build up of dust on the projector or projector light. it could also be one of the camber mirrors in side the projector has come loose or discolored. if the menu comes up ok then it is the avi board control chip as the projector is separated from the other boards and it gets its signal from this.

Images have some ghosting, but convergence lines seem to be OK. For example, white images have a yellow shadow to the right of image. Any suggestion?


Some easy steps to determine where and what your problem is:


1) In customer menu select convergence and then advanced (done with the Mitsubishi remote) look to see if grid of lines straight and if "yellow" is seen there.

2) Look to see if it happens when DVD etc played; If only on component from a cable or sat box but not on tuner or DVD inputs it is not the set.

3) Go to a channel that is in black and white and in customer menu turn COLOR all the way down: is problem still there or not?

If problem is not convergence and is present on all inputs it will be a problem with one of the three CRT boards; they plug onto bottom of each of the the three picture tubes this set uses; yellow suggests a problem with the blue one______loss of blue may give you a yellow smear around things/ red and green equal yellow.

You do not need to take the set apart for this.

Let me know what you find, the more you rule out the easier it is to know where the problem is.

Ok, explain somethings to me. Which parts did you replace? 3.9 ohm resistors will read about 2.2 ohm in board, they are in pairs.

Was convergence problem different than before or EXACTLY they same?

Yellow, blue and green ghosting of picture. Convergence mode will not allow realignment of the red and blue lines


Hi,it sounds like a light engine problem.Lcd Technology uses 3 chips blue,green and red that create the image ,when they start to fail color discoloration will occur.If it's an Dlp pay attention to sounds of buzzing,whirling and high pitch sounds because it could be your colro wheel.

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

Sony 60" LCD projection TV has yellow screen discoloration


I would suggest to try to get this TV fix while still under warranty. Normally the manufacturers give one year.
In regards to the discoloration, there is not much you do but to let the Sony authorized repair center knows about it so they can fix it. Ask them if their work is guarantee as well for how long.
Good Luck.
