Your symptoms sounds like a damaged or intermittent convergence IC.

There are two and very large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink.

If your colors line up in the middle of the set and at the top but the picture is concave then you may have a faulty component in the pincushion circuit. When this circuit fails the picture will have an hourglass shape to it with black in the middle on the sides, or you will see square objects as hourglass shapes.

If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon and it should only add the cost of the part to the repair.

You will want to get this symptom fixed before there is a complete failure of the convergence circuit, which may take out other components.

I hope this information allows you to resolve this issue.

Color problems vizio lcd hdtv


If your tv has a custom settings area, first turn all color down on set so picture looks black and white. Now in color settings look for red blue and green color bars. Use the bars until the picture looks as true to black and white as possible. Also, try changing color temp.

Picture has ghost shadows in the faces of people mainly news anchors. Light colors like whites and oranges also have shadows. What could be causing this?


If it does not really display this when a DVD etc is played via a rear audio/video input it is not the set.

Modern cable or sat signals often are compressed and sets cannot on close up views keep up with the signal--when signal is compressed it causes this kind of issue--no way around it.

Magnet came in contact blue green and red color


Every time you turn on a color TV, a degaussing circuit tries to neutralize magnetic fields on the picture tube face that can cause distorted colors. That degaussing circuit isn't strong enough to clear up the field left by direct contact with a magnet. You need an external degaussing ring to clear up the funny colors. You can see what one looks like here. You might be able to find one for sale on eBay or borrow one from someone in the TV service business. Or you can take the TV to a shop where they can degauss it for you for a small charge. Just be aware there's a chance the picture tube may have been damaged if the magnet was very strong and was in contact with the tube for any length of time. A thin metal screen called the shadow mask is behind the tube face, and if that was warped by the magnet then the colors will never line up correctly again. If this has happened, even after degaussing the colors will still be wrong. But you won't know until you try. Good luck, and thanks for using Fixya!

I just replaced the color wheel on my samsung hln5065w. Picture is great but there is a shadow on the right side of screen from top to bottom. The shadow on the top of the screen is wider across the screen...


Its a Good Possibilty that its the New Color Wheel causing this,if the colors are not complete on the color wheel then that will be why you are seeing shadow on right hand side of screen.
I know I ordered color wheel for mine and had to send it back,it did the same thing.
I compared it to the old color wheel and the new one did not have Solid colors on it.

Can you see picture behind the shadow? or is it shadow and no picture?

Rings on outside edge of screen and color of entire screen is green,blue and purple


Hello
Your TVs Degausing coil is not working. Degausing coil is one, which fitted around the picture tube internally, to demagnatize it at each time you switch on the tv. if you are using your TV without switching it off by its mains switch, and turn it to an other direction, this effect will occcur. You just switch off the TV by its main switch, and leave it for about 1/2 an hour, and then switch it on, and see whether it helps or not.
If not, the degausing posistor inside fitted on the circuit board of the TV, has to be replaced. It can be located on the power supply input section of your TVs circuit board. Ok.

Colors look like 3-D


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

Screen showing lots of colors caving in on top


You have no power to your convergence circuit. Depending on what model RCA you have will determine which parts are bad. Will cost about $200-$300 for a repair shop to repair.
