SOURCE: Location of MIrrors in projection tv

wd-52525 This is a DLP, I dont suggest taking it apart to clean anything, this is what we call a MICRO display, the imaging device is about 1" square and blown up 50X to the size of the pix you watch, anytime anyone I know has taken stuff appart where the mirror is at has ended up worse off, you say that there is dust on the mirror, what does it look like in your picture? If the spots are quarter size or so and fuzzy edges the dust is inside the lightengine and you want a factory cleanroom to service the LE, the one thing I think you can safely do is pull the lamp and check for dust on it as it can cause issues in pix, other than that I dunno what to tell you, hope this info helps.

SOURCE: Green "halo" around the bright white images

I have a Samsung HCM5535W rear projection TV that had pretty much the exact same problem-- a green halo around bright white images. I researched it on the net, and determined the most likely problem was with the convergence STK-ICs, or the convergence board. I bought a replacement board with the STK ICs and installed it, but no luck, the problem persisted. I decided to mess with the manual focus adjustment on the green crt (i was seeing a green halo), and that fixed it. As it turns out, no replacement parts were necessary to fix the problem in the first place. Hope this helps somebody out there.

Where are the mirrors located on my mitsubshi wd-62327 tv


Here is a procedure for cleaning accessing and the mirrors:

Take the front speaker panel off and you will see two screws on the left and right top corners that hold the tabs for the screen, loosen them then go behind the tv and remove the screws around the perimeter of the back of the screen, 10 total, then remove the front center panel 4 screws and unplug the screen (easy to see which one) then just lift the screen straight up. Onced removed you can clean both mirrors. Dont use chemical cleaners, just a soft rag.

"Halo" Effect


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. 

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.

My panasonic big screen screen has shadows and fuzzy picture


Your TV most likely has one or more possible problems.

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.

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.

Look inside the lens while the set is on. If you see things floating around inside the glass, the fluid will need to be changed inside of each tube. I will post a link on how this is done if this is a Magnavox TV set. Good luck

Foggy HD projection TV


I think your refering to the CRT colant needing to be changed if it has a halo effect on the blue and green colors Also some times your picture can get dingy because the mirror gets dull. Try cleaning the mirror and tube lenses. Use a damp soft cloth on the mirror and lenses not windex.
