WD-65831 White Fuzz Aura

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 now.

    There is also no difference betwen the 1080 and HDMI. I saw a repairman the other day that claims Mitsubishi is aware of the factory defect. i plan to look into this more. Many blogs show a lot of WD-65831 owners are have bulb and lught engine issues. I thought this was the Top-of-The-Line!?

    Ok, well since Mitsubishi already knows about this and our State of The Art TV's are going, going, going fast - What do we do about it. Maybe a class action suit?


    • Has anyone contact them to see what direction they want to take on repairs or replacement?

    • Who wants to start this off and where can we ALL keep in touch to have a mass following toward correction?

    • Any takers? Any of you lawyers?

I have a WD 65831 Mitsubishi television. I love it and have had NO problems so far with it. The picture and letters on the screen seem slightly fuzzy (out of focus). I had the bulb burn out and I replaced...


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.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc

White aura on the whole screen, like a light fog .


This is exactly the problem we're having, too, and we have the same make and model. My sister said yesterday it was like watching TV with dirty contact lenses.

Our TV sits a eye level.
