Question about Panasonic PT-47WX49 47" Rear Projection Television

1 Answer

Alignment issue - PT-47wx49 Panasonic PTV Tubes out of align

Hi. Our PTV (bought in 20010 has a "pinched" center section - so the edges are out of aignment (blue and red separate from green) - we have the manual and followed the set up for convergence - but it's the green crosshairs that seem out of alignment. when in convergence 2 we expected to see 9 equally spaced crosshairs (+) but the center top and center bottom are closer together than the ones on the sides - there doesn't seem to be a a way to adjust this. the result is that we get an inward arc that distorts the image and the color separates on the sides. any help would be welcome.

Your convergence is off. u need to get in service mode to correct this problem. its pretty in depth and time assuming. u need to go to servicemanuals.net and for 15 bucks u can get a service manual. it has every thing u need to fix that tv. i had same problem but i had all 3 colors out of whak. i see alot of people on this forum changing the ic's and resistors to fix convergence problem, (me too)and nothing works. i got this manual and saved me alot of money. its been 3 months since i corrected it and i am still watching it. good luck.

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

Panasonic PT-47WX49 convergence amplifiers


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.

Convergence issue


try fixing the convergence 2 after your've aligned the convergence 1 - the second (accessed via the set up control) let's you adjust on 9 different axis to align the red and blue tubes to the green. you select which + sign you want to adust by pressing the corresponding number for the + ie 1 for the top left, and 9 for the lower right corner.

good luck (note - you cant change the green only the red and blue, if the whole edge is a mess try moving the image (you need to be in zoom mode, and then access the position adjustment via the pitcure set up screen.

Projection Tv Problem


some of these tvs have internal adjustments for everything including alignment which fixes the double image problem. if you remove the cover you will find a lot of little adjustment dials. you may find that they have symbols that show what the adjustment is for. if you want more info. email me at sb1216us@yahoo.com

PT-53WX42 IC replacement


The two convergence IC's are generic part# STK392-110 and Panasonic part# C5AA00000203. Also check for burnt or discolored resistors nearby. Since this is such an easy repair,a schematic is not necessary....The hardest part is identifying the burnt resistors and aligning the green convergence in the service menu.
