Your convergence ICs are bad. You need 2 of them they cost about 10.00 each. If you can solder you can do the repair in about an hour. hey are located on a real huge aluminum heat sink and they will have a number that starts with STK such as STK392-110. Let me know if you need ay additional info.

Sound but no picture


If model number is correct here PT-51DX80 the set is blanking (turning the 3 tubes off for a variety of reasons)

Take a peek inside with set on(carefully) to see if the three lens display light and a picture (red, green and blue).

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.

Panasonic PT-51DX80 - Problem


Sounds like you have some leaky resistors or you got a bad IC.
But did you go in to service mode to line things up start there first then follow the other paths.

Blue line trouble


Hi Kracka,

Are you able to post a picture of the problem?

It sounds from your description that it might be a 'convergence' problem which is when the red, green and blue parts of the image aren't alligned properly.

Check in your menu to see if there is a convergence setting.

Hope this helps

No picture, just red-blue-green lines through the middle of the screen very faint.


The PT-53WX54 is a standard projection set and does not have a bulb. It has 3 separate picture tubes. If you have lost the picture completely, not even on-screen menu, then something has stopped working in your set. It could be a video processor, vertical deflection or possibly a convergence problem. The set should be serviced by a qualified tech familiar with the Panasonic projection sets.
