    will this repair the picture going in and out of focus

  • lindacompton Jun 19, 2009

    Two last questions. You specified kit #2, and the site specifies kit #1 for my tv PT-47WX49E. I see there is no difference except for what the resistors replace. You also state that the kit comes with step by step instructions. Are they provided online along with support when the parts kit is ordered? Looks like all this takes is a little soldering. Thanks for they help.

  • lindacompton Jun 29, 2009

    I repalaced the ICs and the resistors as you advised but this did not solve my problem. It did nothing at all. Picture is still blurry.

  • lindacompton Jun 29, 2009

    My brother inlaw works at an electronics place and they solder alot like this and they did this. The blue convergence is still off and green horizontal is off.have tried ajusting the picture and the color and tint and all of the other picture ajustments are very hard to ajust. Blue is the worst.

  • lindacompton Jun 30, 2009

    They also tested the resistors and said they were ok but did replace with the new anyway. Old ICs were STK392-110T and the new ones STK392-110. Are they the same?

  • lindacompton Jun 30, 2009

    Do you have any more suggestions?

  • lindacompton Jun 30, 2009

    Lets see if this helps you. Lost picture totaly. Have blue,red ,yellow wavy lines on screen.

    Yes it should take care of the issue as the ICs when getting ready to fail will have an intermittant convergence issue such as youre describing

    Yes kit 1 is for youre model . I was going by the original post was under the 47WX53 which is type 2. Yes they send the instructions and then offer free online tech support if you need additional help

    Have you double checked the solder connections especially on the two convergence Ics? As its easy to get a solder bridge or one of the pin pads can lift from the board when removing the old Ics which can cause a brace in the circuit trace right at the IC pin pad.

Tv out of foucs


These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

This is a convergence problem that is either bad connections on the convergence ICs or defective ICs. IF you can solder and feel comfortable working inside the set, you can fiox this yourself. Let me know if you wish to attempt the repair and I'll post more details and instructions.
