    Cost VarianceI have found have the same part # ( stk392-010 ) cost as low as $6 ea. and as high as $56 ea.
    My question is; What's the difference?? Is there a difference between them?? Does price mean something??


    Thank you

    Don't forget to check/replace the pico fuses protecting the ICs as they commonly are affected in the ICs are.

Hey, found the problem. Your Convergence IC chip went bad. Buy one at Bluestar International Components (bluestar-online.com) - order part number STK392-010 for 6.99. I've read that there are two in the system and replacing them both at same time is a good idea...so, order 2. Now, if you are handy, it will require you to open the back of the TV and solder out the old chip and replace with new. If not, then you might as well call a TV repair person and have them fix. However, every place I've called works on a minimum fee for "large screen TVs" - the cheapest I could find in Atlanta was $399 minimum service fee. So, I'm going to risk the home sodering job .... it's a 10 year old TV and as good as it's been to me, if I screw it up, I feel I've gotten my money out of it. Good luck with your repair. My parts are on order.

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

Double picture & color problem


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. This is called convergence.

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,Akai2_bing.gif,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link 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 - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

It was a convergence problem, both chips goes bad bad also look for bad resistors around the circuit? This is not an easy repair for non skilled person? You need to realign it after replacing the chips? Don't be cheap pay someone to do it right?

Joe, did you have a tech confirm it`s the yoke? Not a common problem to have a yoke failure, maybe yoke return resistor(s) or possibly bad convergence IC`s, poor signal from DCU (digital convergence unit).
