Question about Panasonic PT-53WX42 53" Rear Projection Television

Center Target Blue Convergence and Contrast Adjustment

I have been working on my daughter's Panasonic PT-53WX52F RPTV, which had bad convergence amplifier IC's. Originally the blue convergence was not adjustable on targets 3, 6 and 9. I changed the IC's today and now have full adjustment. Here is my problem. In the Convergence Adjust 1 Menu, I am unable to bring the blue far enough to the left to converge with the center target cross. The blue has a good adjustment range, but when I am at the left hand limit, the blue is still about 1/4" to the right of the center target. In the same menu, the green is adjusted to the center calibration points on the frame, and the red adjusts to the center target just fine. In the Convergence Adjust 2 Menu, I can adjust both blue and red to converge on all 8 targets. Is there a physical adjustment for the blue CRT for the center target (or an adjustment accessable through the service mode)? Please provide instructions. Also, having cleaned the lenses, the picture is plenty bright but it seems to have too much contrast with a loss of fine detail. There is no Contrast adjustment in the Picture Menu. Is that also a Serviceman Mode adjustment? Any help would be greatly appreciated. Thanks.

You can get to the convergence menu using either the front panel buttons or the remote, but once you get there see if you can adjust either red or blue in any direction. If you can't adjust both colors in all directions you will need to replace the convergence chips and possibly a few low value resistors. If you need more details simply reply.

Convergence Problem and Contrast Adjustment


Have you checked all of the resistors inthe convergence circuit as well? If not, check them for the correct impedance.. Remember, you have to pull one side of the resistor out of circuit to measure it correctly. 
If all of the resistors are good, then you have to do a coarse convergence adjustment on the set through the service menu.. if you need the service manual for the convergence directions, I have one uploaded in the technicians corner of techlore.com

Panisonic projection tv pt-53wx52f


There is a mechanical adjustment on the tubes themselves when it was dropped it could have knocked it out of alignment, or the Convergence ICs are bad with is a common problem with CRT projection tvs.
Mechanically adjusting the tubes can be tricky I wouldn't suggest working on it unless you have some kind of experence with tvs. But if you do adjust the red and blue to the green.

PT-47WX53G green convergence and wave on bottom of screen


Had same problem with Red. Could not adjust. Funny broken lines. Found this link:

http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html

Replaced the ICs. Was disappointed at first 'cause it was still all bowed out, but then realized that the Convergence 2 "target" can be changed with the number keys. Working thru 1-9 and going back to readjust as necessary adjusted each one into perfect alignment.

Problem solved. TV works great.

I should add that while I am reasonable technically adept, I am a software geek and never soldered before... hardest part was getting up the courage to dive in and do it myself. Glad I did.
