Question about Panasonic PT-51DX80 51" Rear Projection Television

Panasonic PT-51DX80 - Problem

I'm getting green wave starting at the bottom center and goes up to the left. If there is white letters on the screen there will be green letters above them.

I tried the convergence and it I can get it all lined up but the green is still showing on the screen.

I thought I read somewhere that another appliance could cause some interference. Could a ceiling fan that is in the same room cause this issue?

Thanks for your help.

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.

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).

You will need to replace your two convergence I.C.s.They are two large IC mounted on a large aluminum heat sink.Replace both,look for any burned resistors near them,replace those if needed,and readjust your convergence. Good Luck

Let me know if you need any further help

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.

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.
