Good day, BrianJack608;
Sounds like you may have a circuit problem, the convergence IC's may have failed, the STK's IC's is very common problem with TV. Before you attempt replacing them try this:
THE CONVERGENCE CAN BE RESET BY PRESSING "MENU 12596" TO ENTER THE CONV MISC. MENU THEN "8970" TO RESET.
I hope this was helpful, good luck, big IRISH.

Ghosting or a 3D image. A yellow and blue ghosting or shadowing image. Looks much like the top picture in the "picture ghosting image" entry. Is this a convergence problem?


Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

Ghosts


How old is ur tv...? Cos the wear & tear is the cause for this ghost appearance. The repair for this is only temporarily. It can not be eliminated completely.

Generally the blue ad yellow colour can be removed by a tool which is available with a tv technician. It is not very expensive to do this. Hoping to hear from you.

Thankyou

Blueish hue throughout picture, like a blue ghost a couple of inches to the right of objects on the screen


Your TV's Convergence may be out of line. To adjust this do the following.

1) Press the Menu button on your TV/Remote
2) Scroll through and select the "Advanced Features" Menu.
3) Select Blue Convergence
4) Use the V keys on your remote till the cross hairs are all lined up in the middle of the screen and the center one is white.
4a) You can use the "Video" button to switch between the red & blue cross hairs.

Samsung tv model # HCP4363WX Ghosting


The convergence board that you replaced will not correct the issue that your describing as your model has the convergence amp circuits located on the Deflection board. You would need the deflection board which is available at the following link. It also has a picture of the board which is in your model its the large board on the right with the Flyback and both Convergence ICs on it.

Color is distorted. Green, red, and blue ghosts


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV 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 from the link below.

Common Symptoms include....
  • 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.
  • TV shuts off after powering on - TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Red and blue ghosting,


The most likely cause is shorted convergence chips and possibly a few pico fuses.

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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

I have what I believe is a convergence problem. The red line curves down at the sides on the adjustment screen and when I am viewing TV the picture has a red ghost curving up at the sides of the picture....


Hi, this is a convergence chip failure and it can only be corrected by replacing the entire convergence board in this unit. This Board regulates and collaborates the RGB streams. if there is an apparent malfunction, it will become impossible to correct the issues you are experiencing at this time.

Simply replacing the convergence board or chip set will fix this issue.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same 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.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
