Convergence adjustment @ 52MH84

I know this question is old, but here we go again.... I have a 52MH84 with a convergence problem. All the instructions indicate to enter the service mode and then press the "yellow" button on the remote. Problem is I do not have the original remote (CT90159) since it is no longer available. I replaced it with a dynatron MR120 miracle remote which works fine but does not have a "yellow" button. Can someone tell me what the yellow button's normal function is on the original remote so I can try to figure out which button duplicates this and thus enter the convergence adjustment menu? I can get the screen to go entirely red, green, blue.... but cannot find the convergence grid

Picture is distorted blurry


Model number indicated is prone to convergence problems; red or blue shadows around writing or letters---

The model indicated uses two of the STK-392-570 convergence chips; they are located on a large metal heat sink with fins at the front of the middle board inside the set.

The board has to be removed to replace them.

A pair of the chips can be purchased on EBAY (where I buy mine) for about 15 dollars-----total parts cost to fix set should be under 25 dollars.

I also have repaired hundreds of these sets and have:

Start to finish, step by step instructions for this repair in this set; they tell you everything you will need and exactly how to do the repair.

I can if you request post the instructions here for you for FREE.

I will attach a photo or two of typical convergence problems so you know if it is your problem and a photo of a typical convergence chip.

If all this information helps you, rate this solution as very helpful here as I do this for free.

Sony kp-53xbr45 please let me know step by step how to enter convergence service thank you


Hello,

To enter into the convergence service of your sony, follow the steps below;
  1. Press "Menu" on the remote control. Use the up- or down-arrow button to move the cursor to "Setup" and then press "Return."
  2. Use the up or down arrow to move the cursor to "Convergence" and press "Return." This will bring up the convergence-adjustment screen.
  3. Press the up or down arrow to move the cursor to the line you want to adjust (either vertical or horizontal for red and blue) and press "Return."
  4. Press the up or down arrow again to move that line until it converges with the center green line and press "Return."
  5. Repeat to adjust the other lines until all three lines converge and are seen as a white cross.
  6. Press "Menu" to exit the convergence menu and return to the original screen.
You can as well follow these steps;
  1. Press the "Power" button to turn your TV on.
  2. Wait at least 30 minutes before you adjust the convergence in your television. This allows your TV ample time to warm up before you make the adjustment.
  3. Turn your TV to a cable channel or to an antenna channel with a picture that you can see. A music channel with a static shot of music notes isn't the kind of picture you need. Instead, look for a picture like what you would see on a movie, sitcom or drama.
  4. Press the "Flash Focus" button located in the front panel on your TV. You may need to open a hidden compartment on the front of your TV to access this button. The convergence will repair itself automatically after you hit this button. It may take several minutes.
Any of the two processes are detailed steps on how to enter your convergence service.

Take care

Convergence will not line up after replacing ic & resistors


Did you replace the resistors when you replaced the convgence chips? If one of them was bad you would still have the problem.

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

  • 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 replaced. This is 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 email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.

Convergence


Touch-up Convergence adjustments Enter the Digital Convergence Mode (DCM) by entering 0-6-2-5-9-7-(Status or Index) on the Remote control. The following menu will appear: Select an active channel or Aux Input. A signal must be applied to the set when performing convergence. If any Customer Adjustments need to be made, the Menu button can be used to toggle between the Customer Menu and DCM. The MPOSD ADJUST is used to center the Customer Convergence grid. A highlighted cross will appear along with the Convergence alignment grid. The highlighted cross should be centered onto the center of the Convergence grid. To perform a Touch Up Convergence, highlight SELECTION and press the right cursor button on the remote. The following menu will appear: Selections STORE, RESTORE FACTORY, and RESTORE DEFAULT are not shown after selecting SELECTION. Press the cursor down button on the Remote for these selections to appear. RESTORE FACTORY loads Convergence defaults from the Factory Loaded section of the Convergence Memory IC. RESTORE DEFAULT loads Convergence defaults from the sets software. To perform a Touch-up Convergence: 1. Enter the Convergence Mode and select RED TO GREEN or BLUE TO GREEN. Do not select GREEN (Green Geometry) without placing a Template over the screen. To perform Green Geometry, refer to the Complete in-depth Convergence. 2. Use the Cursor buttons on the Remote to Navigate from one adjustment point to another. Press the Status or Index button on the Remote to select ADJUST. Use the cursor buttons on the Remote to adjust the Red to Green or Blue to Green. Press the Status or Index button again to navigate to the next adjustment location. 3. After Convergence alignments are complete, press the Menu button on the Remote to return to the SELECTION menu. 4. Highlight the STORE selection and press the right cursor key on the Remote to save changes. 5. Use the GREEN TO RED or GREEN TO BLUE selections to perform convergence when the Green CRT has been replaced.
