Red convergence problem

When I turn on the TV, the red is off and I went into the menu to adjust the convergence. I can get it to adjust fine in the middle column, however, the side crosshairs are about two inches off and will not even move towards the crosshairs. I was wondering if it would be wise to go into the service menu and adjust it from there and see if it stays. I was also wondering if the two IC's could be the problem assuming that they control the position of the red image or if I should just replace the entire convergence board.

Yes I think the IC's on the convergence board are bad. This board is no longer available from Samsung but is available for repair or a swap from http://www.ptscorp.com. Find the telephone number and call them. or you could replace the two ic's on the board. Good Luck

Tv out of foucs

These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

My tv went multi colored take it as it looks like a 3d television

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.

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.

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. Power light will blink. 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. And you should be able to get the grid straight.

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 fix

Convergence On Panasonic PT-47WX54j

You dont need codes for the service menu you need to repair the convergence circuit. If the lines wont line up in the customer menu they wont line up in the service menu either. Do you know how to solder? If so we can fix this yourself with a little instruction. Otherwise you will need to call a repairman. A good repairman will run you $300-$500 depending on your area. Let me know what you want to do.

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.

Convergence problem w/ red horizontal only-WS-65807

Do not try to adjust anything yet!! Adjustments do not get out of alighnment all of a suddenly. The convergence adjustments are there to do minor aging alighnments. I would first check for bad solder connections on the convergence IC's first.
