This is a problem wit your stk392-110 convergence IC's - One has gone bad and the both should be replaced. Also, check the large resistors near the convergence IC's - it sounds like one of them may have burned up..

Not a projection set if 32 inch---If looks like blotches try turning set with it on to see if they change--if so you may have not plugged the degaussing coil (usually a two pin plug) back in when you did the repair--it goes on the power board.

The picture is blurry. does anyone have a solution to this or has anyone had a similar problem.


I have a blurry screen and the top of it the picture is curved a bit. I was told to adjust the focus knob but I don't know where that is in the back of the TV. I took off the back and couldn't find it. I also tried to adjust the manual convergence and the red would not adjust only the blue would align. Any suggestions.

Screen


What you may have needed to do was adjust the green & blue crt screens to match the red. Go into your picture menu adjust, turn color all the way down to a black & white px. Now adjust each crt screen so that you end up with a true black & white px. Then adjust each focus control to get a sharp px, have your tv on a channel like the home shopping network so you can adjust each crt focus one at a time for clarity by cover the other 2 up. Then go back into picure adjust & turn color ahlf way up, you should see a better px.
