I have a WD-65831 and the picture is very fuzzy and there is a whilte aura around anywhere that has white. also the picture is not very crisp anymore.if I try to fix it then the screen is really dark... but in order to
see anything well I have to turn up certain settings and then it is
incredibly blurry... This TV was awsome and it is going down hill fast,
I have alredy gone thru 2 bulbs and it is just a little over a year old

Projection TV sets have two very common problems oulined below.
Problem #1: Convergence Chip Failure ( common problem )
Here are some of the most common symptoms and example photos of a convergence problem
Screen looks 3D
Colors don't line up
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed or warped.
No Audio/Video - TV Makes Chirping Sound
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence section.
Try to adjust the red and then the blue convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.
Problem #2 CRT Fluid is Cloudy
Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.
