Why are my prints only printing the reds and blues in photos?


Please next time put the question in the correct category. I still will try to help you.
If your printer does not tell you any cartridge is empty, and it still does not use that colour it could be the nozzles of one cartridge are blocked. Check this by printing a test page, as told in the user manual. Sometimes called an alignment print.
Then check if all colours appear correct. Looks like yellow is not working correct.

Possible that the alignment of the projection has gone out of alignment. so it must be reset with a alignment and colour setting test pattern.This might require expert help for perfect setting. get estimate.

I have 3 thin lines red, green,blue at the top of the screen, from side to side and slightly arched. I tried the convergence, but it didn't help. Is this a costly repair or can it be done myself?


It is alignment problem & needs lot of patience, expertise to align LCD panels. To align slightly loosen the screws on red & blue panels. Switch on the TV with input source as computer as it has steady graphics. Align for red & blue by slightest movement using light taps with screwdriver sideways. When you are satisfied, tighten the screws. If it is one pixel height line, just neglect it. That much error can be expected.
WARNING: If you are not sure, do not carry out the alignment. Otherwise it will go more out of alignment.

Convergence problem? Blue shifted to the left, red/green are okay


If your model number is the PT53WX53 its a rear projection CRT television not a DLP. The PT53WS53 uses two STK392-110 convergence ICs. If you verify the model number of your set I can assist you.

Red and Blue slightly out of alignment


If constant all over the screen it is the static convergence that needs adjusting.
The green is not adjustable!
Move the red magnets with the blue covered with a piece of card to align with the green and then move the blue with the red covered to align with 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.

You are on the right track. The problem is actually with the green convergence IC that controls the alignment. The convergence ic's take the information from the 3 pictures and align them into one picture on the back of your screen. Although this is an economical repair it is complicated and should be left to a quailfied service technician. If you are not sure of a local technician, panasonic's website has a servicer locator that can guide you to one. Hope this helps
