Blurry picture


Sounds like convergence failure. (Colored shadows of images.)

Color shadowing on white lettering


This is called convergence.
If the TV has auto convergence or 'Flash Focus', run it. All projection TVs have customer controls for minor adjustment. Give it a go with the menu or the remote convergence controls.
If not, this is a common adjustment made by a technician on a house call.
If the error is really big, say the colours are curved or you can see clear separate letters and things, you will need the convergence repaired. Get a quote - Usually about $300- $600 in home service.

Convergence problem


We need a better description of what you mean by shadowing. However I am assuming: 1. You mean it ''bleeds'' off to the right when you have something with a hard red/blue drive. 2. When you turn the contrast and color down a bit it gets better. unfortunatly I cannot tell you how to fix convergence, but I can think of some other possibilities. In this case the red/blue emmision of the crt is dying off and going into saturation when driven hard. To fix, replace with a new picture tube/crt. In some cases you can get a little more life out of that tube (with a watchable picture) by having the screen, focus, cathode bias, and drives slightly readjusted. It will take someone with experience in doing these adjustments on a weak tube to get it looking as good as possible. Given the construction of the cathodes (guns) in that crt, only a very low level crt reactivate should be tried on it. The hard rejuv most crt testers give is highly likley to completely destroy the cathode on that crt.

Distorted Color and geometry of Picture


I've posted this solution several times but here goes. Try setting up the convergence through the menu by accessing the convergence setup menu. If this fails to work you have a bad digital convergence box and need a tech to replace it. About $60 to $100 fix.
