Fixing color convergence red and blue lines


most TVs have an adjustment for convergence in your on screen menu, go into convergence of service menu & try to adjust; it it is still too far out of convergence contact a service technician as convergence issues can be very difficult to resolve unless you are very sure of what you are doing.

"Perfect Focus" problem on Samsung HCN4727W


You have a bad sensor, a bad digital convergence board, or the new board is not working correctly. I would start by swaping out the convergence board or exchange it for another one. Good Luck

Need code to enter on remote to engage multipoint convergence adjustments.Need save proceedure after adjustments are made & exit proceedure for RCA Projection TV Model # HD52W59, ITC 222A


Hello,

To get the code to enter on your remote to engage multipoint convergence adjustments, you need to contact the rca customer care for that, you get them your model number and they will get your code for you.

To process and save the adjustment made, follow the steps below;
  1. Look through your manual. Your manual will always give you the most specific directions for your particular model. Look for an "adjusting convergence" or "set manual convergence" section.
  2. Enter the menu on your TV. Use the remote control and bring up the menu.
  3. Choose "Convergence." This may be under "Picture Settings," "Function" or "Advanced Options."
  4. Select a color. You will have red, green and blue to choose from. Do each one, starting with red.
  5. Press "Enter." A crosshair pattern will appear on your screen.
  6. Adjust vertically. If there is a horizontal red line visible, press the up or down arrow keys (or channel up or down) to adjust the convergence until the line is superimposed on the horizontal-center line of the white crosshair.
  7. Adjust horizontally. If there is a vertical red line visible, press left or right (or volume up or down) to adjust horizontally. Do this until the line is superimposed on the vertical line of the white crosshair.
  8. Save settings. It is important to save your settings when you are done, instead of simply exiting the menu.
  9. Repeat these steps for all colors.
Take care

Red color convergence issue; Red lines are curved


This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Mitsubishi 55411 projection tv has red band across bottom


go into the customer menu and select convergence with the original remote; if either the red or blue will not move in some direction, you have a bad convergence IC(the WS-55411 uses two STK-392-110 CONVERGENCE IC chips)

Panasonic 53'' 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. 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 TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

You can see some more examples and find a fix here

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.

Red Converance problem


Don't try to solve this in the service menu. The lines that do not move in the customer convergence menu will not move in the service menu. And, you can do some serious damage if you hit a wrong button while in the service mode. You have bad convergence output ICs. You can expect to spend $350-450 to have this problem fixed by a qualified technician.

Converging green?


jaymz, you can`t move the green, the green tube is always mounted in the middle and is not adjustable from the convergence menu. red & blue should be converged one at a time on top of the green, once you have accomplished this the crosshatch grid will be white and that means your done :)
