SOURCE: Convergence problem

you will need to replace the stk ic's they are mounted to 2 large heat sinks in side the tv. the ic numbers are on the chips themselves. i do believe it is stk392-510 for sony. once you have the number you can buy these anywhere online. just put new ones in and should be good to go. if this doesnt work then there are a few resistors and fuses by the ic's that sometimes fail.

Your TV has gone crazy on you because your convergence IC's have gone bad.   These IC's operate at a very high temp, and usually only last 4-5 years.  
If you remove the back of the set, you will want to look for the BIGGEST heatsink in there, on that heatsink, you will see 2 lage IC's , probably STK392-110, or STK392-120's or something close...regardless - you can go on ebay to order the new ones, but MAKE SURE they are Genuine SANYO IC's and not counterfiet cheapies. the cheap ones may only last 2 months.. 
You will also need some "Heat transfer paste" - you can pick this up at radio shack.   Once you remove the old IC's, test all the large resistors near them.. pull one side of the resistor out of the board so you can check it out of circuit. they will usually have the value in Ohms, printed directly on the resistor, but you may have to use the resistor color code to find out what value they are....However, usually if there is any damage, the resistor will look like it has been HOT or fried. replace the IC's and any bad resistors, and you should be good to go. If you need to order a resistor or two, 
http://servicemanuals.vstore.ca/index.php/cName/convergence-resistors   If after replacing the IC's and any defective resistors, the convergence is still bad, make sure to use a multimeter to check ALL fuses on the boards, --- sometimes when the IC's go, they will take out a fuse to the convergence power supply. If you find any bad fuses, replace them accordingly!   If this STILL doesnt make it look right, you will need to find out how to get into service mode and do a coarse convergence adjustment. This information can be found in the Service manual for your set. If you dont have one you can download it at manualuniverse.com
Hope that helps!

Hi, thank you for visit fix ya.
Do you replace STKs ICs?.
If so, you need go to service menu tv.
With you tv off, press on your remote control:
display + 5 + vol+ + power.
You will go to service menu tv.
NOTE: Be Careful before you do this, because if you don't know step by step convergence adjustments.....YOU WILL MESSED UP YOU TV.
I recommended if you don't have electronics skill, take the tv near to tv shop.
Any question I will be here .
( I need model number tv, please)
Thank you

Sony post convergence repair problem


The flash focus is a joke in these sets--only adjusts a limited area and can make the set look worse--like having a cigarette lighter in your car--not really needed.

Flash focus rarely if chips have been replaced will SAVE the adjustments.

The set stores the convergence adjustments on a board inside--best way to adjust is with the Sony remote to enter the tech menu and adjust there--when done one of the numbered buttons is pressed and Save? in red appears--press same button again and it goes to green which means adjustments have been stored in the set.

The tech menu will also always give a much better adjustment of the entire sceen.

Have you tried the auto converge or flash focus adjustment? This feature allows you to adjust the convergence automatically. If it doesn't work,convergence circuit is faulty. You need to replace the convergence kit, To do this you need some basics on electronics.

Colors are separated red, yellow and green so picture is blurred


lgray1010,

Try using the Flash Focus to/or manually try to dial in the convergence. If you are unable to focus the TV using its convergence adjustment it's time to call the TV repair guy. Figure on between $250.00 and $400.00 USD.

Words and many images have shadows, or ghost-like images. In the past, the flash focus corrected the problem, but now it doesn't


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 projeciton 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.

e87380c.jpg
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

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

How do I get the front panel off my Sony 46in projection tv to adjust the red line conversion.


You cannot - or should not adjust the convergence manualy. The TV has a built in flash focus button on the front panel that you can press. Some sets also have a convergence menu. Use those. Adjusting the knobs in the TV will only make things worse.

If after the Flash Focus™ feature has been performed, the colors on the FLASH FOCUS screen do no line up (converge), press the FLASH FOCUS button on the television to begin the cycle again. If the colors on the FLASH FOCUS screen continues to appear misaligned, service will be required .
NOTE: It is recommended to perform the Flash Focus™ feature about thirty minutes after the television has been turned on and keep the room as dark as possible.
