I've got a Kortek KT-2502LF chassis, unknown 33" tube (the sticker is gone) that's only displaying in the lower left corner. So far I've replaced all of the caps, replaced the flyback, reflowed all of the solder points on the bottom and verified that there's no shorts or cut traces, I've verified that the caps are all at the correct polarity, and I've check the monitor with other known good PCBs, and I've run a magnet on the screen to see if it brought back the picture towards the magnet and it only distorted where it was showing. I'm really at a loss for what to do now. I don't know a whole lot about monitor repairs, and sourcing parts for this thing is also proving to be a challenge.
My only thought is that the flyback itself isn't the correct part. I sourced one that supposedly matches the Du Go part number but not the Kortek part number. The original is Du Go CF-06291 / KFS-61188 and the one I replaced it with is KFS-61088A. I can't seem to find a KFS-61188, and I don't know anything about what's compatible between these things. Or whether this is even causing the problem.
Any help would be greatly appreciated.
