| Philips | 27CE4599-33R 2B | Red raster and red flyback lines | One of the paralelled 75 kohm resistors of red was open, replaced with 47K in series with 27K and fault gone fault seeking in RGB output difficult due to intelligent auto calibrating-cutoff driver with picture mute TDA4580 | ||
| Philips | 27CE4599-33R 2B | 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 |
