Blue Spots on my Zenith D52WLCD TV

I have had this TV a little over a year and the blue colors are really starting to stand out. Is this a problem that anyone has come across and can it be easily repaired? Any help or pricing would help.

    We have a similar problem with a blue tint going down the left half part of the screen about 6-8 inches from the top. The bulb is is great shape. Why are we getting this blue tint and how do we fix it.

    I have the same problem, the blue screen started on the top right corner of my TV and the replace lamp came on the screen so I replaced the lamp and the blue has now covered the whole screen. I can see the picture but the blue tint is getting worse. Is there a pace I can take the TV to get it fixwed or should I just buy a new TV?

White arcs across screen when the screen is dark or black.


Replace a color gun in your KP51HW40. Then adjust the picture brightness to eliminate these rings by turning a little button behind the front (cloth like) panel (the one covering the front bottom half of the set). You may have to to dim the lights to be able to do that properly. The little dial button as is in the middle.

I have some distored blue color across the screen


Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Red, green and blue colours diveded on my TV


ok well "tube" tellys as they are called use an electro magnet to keep the picture stable and colours correct its called gaussing now if you have a speaker or something magnetic nearby it will stuff up the colors but only normally producing colors like purple,green, or white
if you have colors across the screen (that aren't caused by magnetic force) then you need to take it to a repairer or decide wether or not to buy a new one this issue can turn out to be quite hard to fix and can be expensive the different colored electron guns may be burning or burnt out causing pale color or it could be as simple as a power transistor in the H.V supply has shorted out..and causing power issues to the tube.
hope this helps,ben

Green/Blue distorted Colors


Color issues are harder to solve without seeing the problem. It sound like the red amplifier on the crt board is bad. Is there any red in the picture at all? If not, that will be you problem

All color guns out of alignment


Needs convergence amps replaced. Sometimes resistors burn and need to be replaced. This repair requires soldering/desoldering equip. and a trained eye, but usually can be done for 175.00-325.00 at a reputable service center. Good luck, Russmann.
