Remove speaker grill cover on tv lower front.Remove access panel.
Locate small blue push switch = activate convergence grid,then
use 2 & 8 , 4 & 6 , and enter along with adjuster arrows if I
remember right, then magic focus last..............T.

My 57twx20b rear projection tv appears to have 3 images that are not aligned I have been advised it is called convergance failure and the IC's called STK's need to be replaced. What are STK's and how are...

This is a common problem. Its called a convergence failure.

Problem #1) Convergence

  • Colors wont align
  • Video may look distorted
Problem #2 CRT Fluid has clouded over. Symtoms
  • Dull looking video
  • White looking video
  • Halos around objects
  • Red/Orange looking video

You can see some examples and find a fix here...

Blue line Ghost Image on Panasonic Projection TV

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} This set uses two Stk-392-110 convergence IC chips; both need to be replaced along with any of the 2.2. ohm light blue resistors around them; a bad resistor will be white in the middle; You can buy both for less than 13 dollars plus shipping on Ebay.

The chips are located on metal heat sinks with fins and are side by side. They are black(about 2 inches wide by 1 1/2 tall) and should have the STK-392-110 number printed on them in white.

Depending on your level of skill at this kind of work you may be able to do it yourself---if you need step by step instructions contact me---I have them in Microsoft word---start to finish repair including what you will need to do it.

If you are not able to do the repair yourself now is the slow time of year for TV repair shops----It should be fixable right in your home and the repair takes about an hour--I have done hundreds of these sets--some shops charge 300-400 but I do lots of them for 200-250 total cost. Make sure whoever you get changes BOTH of the chips!

Shop around and if they say "needs to go to shop" keep looking; any good tech can do this right in your home.

I do this here for free so if this helps you give me a vote here. If you need direct help contact me.

Blue color doesnt muve up

hi there. sounds like a bad convergence IC. possibly a broken connection(s), parts are located on a large heatsink near the center of the main chassis, part number is STK391-110 for standard definition and STK391-570 for high definition, the location and part numbers can vary from model to model and year to year. hope this helps.good luck and be safe.

Problem continued

Good Day;

When you activate the Mj focus the TV is restoring the data from the TV's digital circuits. So, you have the ability to change the IC's you can do this.

You need to go into the con service mode. Take off the front grill, remove panel, 6 - 8 screws. From the front there is a switch on the left hand side, it is small, white button with TV on. now you are in the service mode, using TV's remote adjust. Make sure you save dat. Go hit on line site get more info.

Goo0d Luck!
