I have Zenith rear projection TV Model IQC60H95W.The blue tube does not work. The red and green project. Is this a bulb or tube and are they available to purchase? The TV was made in 2001


This is a CRT(cathode ray tube) not a bulb. A Bulb is totally different. If you replace one Tube, you need to replace all 3 or the colors will never match properly. However, This model no longer has parts available. Even if they were, the cost would be close to $1000 in parts. I would not recommend repairing this TV.

Picture shows blurry


You will have to determine which of the picture tubes has contaminated fluid. To do this, you have to pull the screen off and see which tube is blurry. You will find a red, green and blue tubes when the set is on. To learn how to remove and replace the fluid, please check the following web site. www.TVRepairKits.com. Be sure you have the model number and know the symptoms you describe to repair this. Thanks for asking and show all hands of support!

My screen is discolored and blurry. Please advise..


Sounds like contaminated fluid. Each of the 3 crt's in your set have coolant to keep them cool. This coolant over time gets contaminated and causes extreme blurry picture. ITs extremely common on the Magnavoxs. Its also a pretty big job. Replacing the fluid isnt too difficult but because the tubes have to be removed it means both physical alignment and electronic alignment will be necessary. Also dont remove the green tube until you have done both the blue and red and aligned them to the green. Then do the green.. I hated doing that job lol.. I dont recommend you trying it and probably wouldnt be cost effective to pay a shop to do it either.. I recommend buying a new set... Sorry

I have a 1994 zenith big screen the picture is showing really dar


It could be that the picture tubes have gone down on emission, there is a prcedure that can be tried to bring up the overall brightness but it is just possible that you will loose some picture quality. If it's a 1994 projo tv i am thinking of the three crt system, a gray scale alignment would probably correct the dark condition in your picture, again depending on how far gone is the emission in your picture tubes, if your projo tv is the dlp system, the bad news is that you could be needing some light engine repair. The color adjustment is possible with the availability of a service manual or in the case of the dlp system, light engine repairs or replacement are available from some on line stores.

The screen seems dark and blurry


take off the front panel carefully, usually 2 screws around the controls. Next, stick your head in and look at the red green and blue tubes. see if they are dirty? if, not look further into the tube using aflaslight and see if there is a white pasty looking substance inside. IF so, you need to clean as you have bacteria growing in the cooling fluid. A big job and you need the gaskets, can order from Mitsubishi tech support..good luck be careful.

I have a 60 inch Phillips 60P8342 and the picure is blurry.


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.

Replacing Coolent


I have the service manual, and it looks like this is a bit of a job. You also need a special coolant fluid, not water. Still, I can't think why this would need replacement unless it has leaked out or you were replacing the picture tube. Are you sure it's not a focus problem?

Picture is blurry


it sounds like the focus block or flyback is bad.sometimes you can put nail polish on the adjustments controls to make it stay.usually they are marked from the factory with white marks check and see if they are aligned.but be sure somebody with tech-skills help you.the flyback usually has a screen & focus control.(the big red wire to the tubes or block)
