Question about Panasonic PT-53WX53 53" Rear Projection HDTV-Ready Television

1 Answer

Convergence IC's I appear to have the same comvergence problem, (yellow and blue seperating at thebottom of the screen). Should I buy the STK392-110 or the STK392-120 ? Is the 120 an upgrade or for a different TV? I have the Panasonic PT-53WX53G.

    installed the new STK392-120 and that fixed the color problem. I still have a slight concave picture. The top corners are ok, but the middle sags a little, and the bottom is up a little. Like an hour glass laying on it's side. Also, I've tried to adjust the Aspect because words at the edge of the screen get cut off. Example: "News Channel 13" at the bottom left of the screen would read "ews Channel 13". There has to be an ajustment to this other than the Aspect function on the remote. Any ideas?

Buy the STK392-120 they are a better chip. Some people say go up to the STK392-150 but i had an issue trying that with a panasonic it keep burning resistors as fast as I could change went back down to a STK392-120 and worked great.

    Yes you can adjust the size through the service menu. However I believe you may possibly have a resistor or two open in the convergence circuits. Its not uncommon for the convergence ICs to take out a couple of the convergence Resistors when the origional ICs burn out.

Ur convergence are dead.Must know how to solders?Have solder iron,solders,solder wicks?Must replace 2 STK convergence IC,and some or all it resistors.Tries websites to buy a convergence kit at Tv repair, to repair it ur sself.The shop will cost $300 for parts and labors.

I have alot of offset blue and yellow in my picture. I tried convergence from the front but it didn't help...what can I do to fix w/o alot of cost in these tough times..?

This problem is related to the convergence, but it requires replacement of IC STK from one of them who control convergence, check both and replace faulty IC STK from new one and your tv work fine again. You can buy the convergence IC's from the link click here.
Thanks for using fixya.

RCA 52 HDTV working fine when suddenly a band of color, red, blue and green appeared at top of screen. Picture curved inward from top and bottom. Picture is blurry and has double images. Television is less...

There could be a convergence problem. Try these:
  1. Press MENU then choose SETUP>AUTO CONVERGENCE.
  2. When Auto Convergence is complete, the Red center convergence menu appears. The cross in the middle of the screen should be yellow. If it is not, use the arrow buttons to move the red cross to overlap the green cross. Press OK when adjustment is complete.
  3. The Blue center convergence menu appears with a cyan cross in the middle of the screen. If it is not, use the arrow buttons to move the blue cross to overlap the green cross. Press OK.

Yellow and blue appearance in upper left corner - ghostly background of screen.

ok, it is a ws-55-511? if blue or red will not adjust in some direction you have a bad CONVERGENCE IC--I have start to finish step by step instructions for the repair of this set with this problem.

If you want the instructions provide me a email address and give me a vote here--I am not allowed to post my email address here--It depends on if you can do this repair yourself--this model uses one STK-393-110 CONVERGENCE CHIP--I can tell you where to buy it and how to replace it--

if you have questions or need more help respond to this posting here.

thats usually a convergence IC failure, Are you able to move the red and blue colors in the convergence adjustment menu?


your having convergence circuit problems, you`ll need to change the convergence IC`s and any burnt resistors in the convergence circuit, if you have questions e-mail me back, good luck, BMW Rider
