I found the solution on mine. To restate, I just saw a thin white border around a black screen. Pressing the channel up or down buttons changed the screen, in some kind of test mode to shades of gray, and red, green, and blue. I started finding a solution when I noticed when on one of the color screens, that the volume up or down buttons brought up a new menu for color intensity. Finally, I got back to the thin white border screen and pressed the arrow keys in the top half of the remote. Finally a TV screen and I pressed the enter key! Voila!

Fixed my own problem lol. Video card needs to be replaced.

Try to consider the following tips:

Smearing out of one or several colors, best seen in txt-mode, my 27CE4599/30R smeared out in red and green, not in blue, fully exchanging the drivers (input and output complete, otherwise the RGB driver will blank the crt) moved the fault to the other color
Replace the 180K feedback resistors in the amplifiers with normal 1/4W metal film instead of 1/8W, they can become open circuited (in mine both green and red were faulty in this way). Change all 3 and not just the defective ones, replace also all the paralleled 75K resistors per color (fe by 47K+27K) to prevent bright color raster (they can also become open circuit)
