My convergence is fine but after professional replacement of the board there is a slight bowing and slanting of in-screen borders and some channels have a little distortion at the top of the screen. The...
First: If the convergence board was replaced--the set may need a total adjustment---this is why most good techs replace the convergence chips and any bad parts instead--also costs less----Second: to enter the service mode (it is done with the set already turned on) should be Mute, 182 or Mute 183---if you get the convergence mode--7,8, 9 will select red, green, blue, 5 will stop the cursor from blinking and allow adjustment---with the cursor blinking 2,8, 4, 6 will allow you to navigate---depending on the remote used--the P mode button will take you across the screen in a series of steps--the remote I use for this has a button on it marked data save--this saves the adjustments. Your remote may have it or a different button for this.
Understand---if you get into the convergence mode---Green determines if the geometry of the picture is straight---red and blue are adjusted to it---to align the green you need to call the convergence mode up and then cover the lens for the red and blue---leaves you with a green grid---then you need to select green and wherever the grid is not straight adjust it--once you get it straight you need to uncover the red and adjust it to the green, and then the blue to the green---green alignment determines if the picture is straight---It sounds like this guy did not try to get the green straight and just adjusted the red and blue to whatever the green was.
My point here is if you paid money for this repair--either he aligns it straight or you should get your money back----GREEN never needs to be adjusted unless the dcu(digital convergence unit that stores the adjustments) has been replaced or the Convergence module has been replaced---I bet if the original convergence module was repaired(chips replaced etc) and installed you would not have this problem.
If the guy replaced the DCU then GREEN must be fully adjusted for a straight picture FIRST! then red and blue adjusted to it.
It is not easy or quick to Adjust the green--maybe he just wanted to get out the door?
