Service code needed to complete convergence adjustments

Both convergence chips need to be replaced and or some resistors and set adjusted.

If have the original remote go into menu and select convergence to see if it will adjust---if not chips etc need to be replaced.

Set most likely uses 2 stk-392-120 chips but a few use the -110 chip.

First: If the convergence board was replaced--the set may need a total adjustment---this is why most good techs replace the convergence chips and any bad parts instead--also costs less----Second: to enter the service mode (it is done with the set already turned on) should be Mute, 182 or Mute 183---if you get the convergence mode--7,8, 9 will select red, green, blue, 5 will stop the cursor from blinking and allow adjustment---with the cursor blinking 2,8, 4, 6 will allow you to navigate---depending on the remote used--the P mode button will take you across the screen in a series of steps--the remote I use for this has a button on it marked data save--this saves the adjustments. Your remote may have it or a different button for this.

Understand---if you get into the convergence mode---Green determines if the geometry of the picture is straight---red and blue are adjusted to it---to align the green you need to call the convergence mode up and then cover the lens for the red and blue---leaves you with a green grid---then you need to select green and wherever the grid is not straight adjust it--once you get it straight you need to uncover the red and adjust it to the green, and then the blue to the green---green alignment determines if the picture is straight---It sounds like this guy did not try to get the green straight and just adjusted the red and blue to whatever the green was.


My point here is if you paid money for this repair--either he aligns it straight or you should get your money back----GREEN never needs to be adjusted unless the dcu(digital convergence unit that stores the adjustments) has been replaced or the Convergence module has been replaced---I bet if the original convergence module was repaired(chips replaced etc) and installed you would not have this problem.

If the guy replaced the DCU then GREEN must be fully adjusted for a straight picture FIRST! then red and blue adjusted to it.

It is not easy or quick to Adjust the green--maybe he just wanted to get out the door?

I do this here for free so if this has helped you take a minute and give me a vote here.

Try replacing the flyback transformer

You can get a free manual if you buy a kit from www.TvRepairKits.com . They will typicaly email one to you if you just ask.

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 are some photos of convergence problems.




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.

SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

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.

Solution #1

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.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

Solution #2


What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Your TV most likely has a Convergence Chip Failure but I have not seen that symptom before.

reset your tv with defaults settings.f chip and resstor blown then it need change.

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.
Here is an example photo....

Have you tried adjusting the convergence yourself?

 

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.
