Need to change blue tube, just unscrew and replace with t.v. unplugged?


No - Your TV has tubes not lamps.

Why do you beleive you need to replace the tube. 99% of the time the problem with this model is just the fluid.

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 white,dull, red/orange, etc. You may even see white halos around images.

Here is a photo of a set that needs the fluid changed.

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

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.

Screen is getting darker



The most likely cause is the blue and green tubes need to have the cooling fluid changed. After many years the blue and green get clouded with algae. The red tube won't have the problem due to the red spectrum kills the algae before it has time to grow. 

The way to replace the fluid for is to completely remove each CRT from the set, remove the drain plug, drain the fluid out the tube, disassemble the lens, give it a good cleaning; then reassemble; add fluid; and reinstall in set. If you check with the site www.TvRepairKits.com they are working on a kit that includes the fluid and photo instruction guide.

Fluid Mold


yes it more than likely is related to the spill.
this model is famous for fluid leaks. each projector1.gif tube has a reservoir on the front of it with a fluid in it. this keeps the face of the tube cool.
this depends on how bad the damage is in the tv. in most cases we can reseal the tube and clean up the fluid 400-600.
Once you
take the tube out you will see where it leaked. The problem is that the
frame on the CRT that the heavy screws with springs are mounted on (that
hold the lens coupled to the CRT) is weak and they can bend. We have seen
several that have leaked after the customer moved the set. You can only
tighten them down so much because the frame bends. It is just stamped metal
and not welded at the corners to support the bend.

We remove the CRT, clean it all up, add a very small amount of RTV sealer to
the gasket, reassemble, let the RTV cure thoroughly and refill with coolant.
The extra sealer should prevent future leaks. Haven't had a recall yet.
Mits says replace the CRT...too costly.

You msut check the yokes carefully as well. If any coolant gets into them
you can end up with shorts there and a mess.

Clean the boards carefully and repair any corrosion damage. The coolant is
ethylene glycol and glycerine which is water soluable.

You can also check to see if you have bad fluid problems, by looking down in your crt's with a flashlight when you unplug your set and see if you can notice any particles that should not be there. Look at all three and see if there is a difference. It should be clear, if not then you need to change fluid and clean.
It sounds as if one of the picture elements (there are probably 3 for R-red G-green B-blue) has gone bad and it is most likely the green one. Sad to say it will probably cost you more to have it fixed than it would to buy a new TV. Most places will not even look at a TV for less than $85 or so, then they will add parts and labor... if they can even find parts.
