I had posted a problem i had with a KDS VS-190i monitor. The H-size/pincushion and trapezoid was not working. I have replaced R439 with a 2.2k (I couldn't read the value , but i could still read 1.5k on that resistor. So i thought 2.2k was good enough.) Now that all works!
Now i can see mostly above the Start button of windows , or around the clock , that red pixels are bleeding on the top of the text. Red pixels were bleeding from most of the text, giving it an illusion of inclarity. I have tried the pots on the flyback, adjusted them to get the best results possible, that still doesn't fix the red pixel bleeding. There is also 3 pots on the top of the tube, labeled Yx i turned those and it cleaned up the red pixels bleeding from the white text of my desktop icons, but some red pixels still remain above black text.
What should i be looking for now? Could there be more pots to adjust? I've tried decreasing the amount of red in the picture but the red pixels just dim instead. Should the 3 pots labeled Y on top of the tube be able to correct that? Its very annoying because right across the taskbar a red line appears.
Also , where could i find .jpg test files .. to setup my screen for the best results? I'm sure there's a collection of patterns and pictures used to set the best picture possible?
Any input is appreciated
