Blurry shadows in red and teal.

Characters on picture look double and the colors red and teal are dominant on the screen. I tried to adjust the convergence menu but the bottom left red cross will not overlap the green. It will not move left or right only up and down. Also the red cross in the upper right hand corner will not overlap. It will not move left or right. Please let me knpw if I can fix this myself or what needs to be done. Thanks for your help.

On left half of the screen [ KP51WS510 ], a redish shadow showing


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. 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, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV2_bing.gif may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

Characters on picture look double and colors not lined up


HI, the convergence board or unit is failing at this point. you will need to replace the entire board in this case. most of the components are damaged.

The convergence board is the main regulator of the RGB stream. it also controls color focus as well. replace the convergence board asap.

Color adjust


Greetings!

Adjusting the picture tubes is a scary proposition, but since you have already done it...
The easiest way to balance the gray scale is to turn the color all the way down on the set. The next part is easier with two people if the screen controls are on the back of the set. This is the part you saw that has six small knobs on it. There are control for the focus of the red, gree and blue and for the screen level of the red, green and blue. You will want to adjust the screen controls in an effort to get the picture black and white (this is why you turn the color down), hence the term "gray scale". Just make slight adjustments, take your and be patient. It will take some time, but you will get your picture balanced back out in time.

Hope this helps!

Has a shadow on picture. Red, Green is not alligned


You need to set your convergence. Check your owner's manual on how to do it. I'm not sure the exact procedure on that model, but usually you can find it in the setup menu of the tv. What you're trying to do is line the red and the blue up perfectly with the green so that they all blend together to give you one picture.

HCL4715W Rear projection blurry


The focus controls on this set are in the front behind the bezel. I'm not sure, but, I think on this age of Samsung, the screws to the front bezel are on the back side of the set. After removing the screws from the back, the front bezel snaps off and the door behind the bezel need to be removed. Watch the wires connected to the bezel, they need to be attached in order to turn on the set. The focus controls are on a black control block (there are three of them, one for each color). Adjust each color for sharpest picture. I use words on the screen for alignment. Each CRT board has a screen control (Adjust each slowly until retrace lines appear on the screen and then back off until they disappear). You may turn off the color and make sure that the picture is black and white. If it is not, then, which ever color is dominant, back it off a bit with that screen control. Facing the set, Red is left, Green is middle and Blue is on the right. Use only one hand inside an operating television. Do not touch the board, just the controls. This concludes television alignment 101. Any questions respond to this post and I'll reply.
