Question about Panasonic PT-47WX49 47" Rear Projection Television
1> I'm in urgent need of service manual for 5 year old PT47WX49E, Which is giving blue convergence problem. I would greatly appreciate if you could email me service manual for it @ firstname.lastname@example.org.
2>Also would you know; how to get into "service man mode" for this type of TV ?
3> I have a single chipset of STK392-110 convergence correction IC. I'm little rough on soldering (especially undoldering), can someone point me to a useful link.
Thanks in advance !!

I would like to thank everyone for their posts as it helped fix my blue convergence problem om my six year old PT47WX49E.
Even though replacing the STK392-110 chips resulted in a fix, I don't think either of the chips were bad.
While cutting out the old chips, I discovered five out of six of the middle pins were never soldered! Unfortunately one chip was already replaced and I was half way through removing the second.
When you have a convergence problem, take a close look at the pin connections on the back side of the circuit board. Use a magnifying glass if you must (use one even after soldering to inspect your work).
Hope this helps save someone a few hour work.

How do you get out of Service Mode if you entered into it but didn't make any changes, just used the power button of remote to scroll through the 6 menu choices and returned to the CKOFC09 title on the top of the screen? Please help!

Here is a link where you should be able to obtain a service manual for your set. http://www.asm-service-manual.com/
To answer your second question. You have to be careful. Make sure you write down all current settings so you dont mess the Television set up worse. The code is the following.
Accessing the Service Menu w/ Remote:
TIP: Use a dvd that has an aspect ratio of 1.85:1 (I used Starship Troopers) and make it just fit. Don't squeeze too much vertical as the AA9a60 may have some tearing on the top of the picture....this means you will have to cheat and increase horizontal size, cropping some info off the sides.
