CONVERGENCE BOARD PROBLEM?

I have a 43FDX11B model that I was not able to manually adjust per the digital array feature described in the manual. A local authorized service tech said he would need to remove the board and take to his shop. What would be a fair ballpark estimate of fixing as opposed to replacing the component?

  • HCH43 Feb 22, 2009

    If I were to replace the "Board" to fix the convergence problem:

    Where is it located?

    Do I need special tools?

    Where can I buy a new one?

    Don't the projectors need to be adjusted? And can I accomplish the adjustment on my own?

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence 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.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaCONVERGENCE BOARD PROBLEM? - 2c07611.pngs a common problem.

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.

Screen out of adjustment

steamjet1,

Try to fix it by using the convergence adjustment. Use the manual method to set it if the auto feature fails. If you are unable to focus the TV using its convergence adjustment it's time to call the TV repair guy. Figure about $300.00 USD for your model.

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.

Is there a Magic Focus function on 53XDF01B?

The correct model is 53fdx01b. There is a mogic focus button on the front of the set. Procedure for Chassis DP05F, DP05, HP11, HP12:
1. Press and hold the DIGITAL ARRAY or CONVERGENCE ADJUST button on front panel.
2. While the button is held down, then press the INPUT or ANT button on remote control.
3. The unit will now be in the DCAM.
NOTE:
1. Proceed with digital convergence adjustment.
2. Remember to save the correction data.
3. Units with MAGIC FOCUS only - Failure to initialize MAGIC FOCUS sensors after saving
convergence correction data will result in a STATIC (+) display when MAGIC FOCUS attempts
to run. The technician will then be required to access the service only switch behind the front
cover to get back into the DCAM to initialize the sensors, since the procedure to access DCAM
without removing the front panel, requires MAGIC FOCUS to be running.
4. To exit, press the POWER button on the front panel.
