Panasonic PT-47WX49 convergence amplifiers

I started out with the red picture out of alignment, I bought new convergence chips , replaced them but still have the same blurry picture. neither the remote or the guns will re-align them perfectly. this pt-47wx49 is only used for my sons game play in the basment but would still like it to be used, any info. on these problems would be great,, thanks

Often when the convergence ICs there are small valued resistors close by that open up as well. These resistors are used as current limiting resistors and when the ICs fail, they short causing excessive current draw. I don't have the manual close by, so this is from memory, but look around the ICs. You should see some low valued resistors tied directly to the pins of the ICs. Check those for proper value. I suspect 2 will be open (infinity reading) rather than their expected values. This means that there is effectively no power going to the ICs.

Let me know what you find.

Check R7059 and R7050
check for 2.2 ohm.
if not 2.2ohm replace them.
values are 2.2ohm at 2 watts
also look for bad soldier around all serounding resintors.

This kind of problem occurs due to failure of convergence output chips located on main circuit board of tv and replacement of convergence output chips will hopefully solve your tv problem.
Soldering work is involve to replace these two chips so have local tv repairman for that job if you are not familiar doing so.
Thanks.

The picture is producing a double image which appears to be in red only with a slight bending of the images on some parts of the screen.


Your Convergence ICs have failed. It is very common on rear projections. The solution is to replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu. It is about a $300 repair at a tv service center. You will need the service manual if you decide to do this yourself.

Try This:
When you notice the symptons Use this simple test to verify.
Go to the users menu on the tv.
Look for the converge option probably under setup or video setting. Converge is short for convergence to align the red and blue colors to the green color.

If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section.
If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.

If you can move both in each direction then the problem is something else.


Note if one STK chip fails, you replace both regardless.

Everything has red highlights. but adjusting with the remote does not change things to correct the problem?


Go into the menu with your remote a click on picture next scroll down to convergence and click on it. Follow the on screen instructions on how align or converge the diffrent color lines togeather. It will usually have a white cross on the the screen. This should solve your problems if not have a tech replace the 2 convergence chips in the back of you set

Vertical lines dont align and green tint


First do a convergence on your set go to menu select picture then scroll down to convergence then press select again. Next follow the on screen instructions for static convergence. If this doesnt solve the problem check all the capacitors in the convergence section of your TV. If problems persist replace both convergence chips. Please have tech do this for you.

What is a convergence amplifier


The convergence amplifier is a three channel Integrated circuit which controls the convergence alignment of the three picture tubes in a rear projection TV. Your convergence amps are STK392-110 there are two of them also check the six 2.2 ohm 2watt resistors

Uh oh... the colors are curved and wacky


replace the amplifier IC chips for the convergence.  part # stk392-???  could be from 040 to 120..  90% chance that'll fix it.
