Hi, have a Samsung GQ50Q60AA, that went into protection. I measured CKx lines, found no problem, but noticed on the left side from the back of the TV, that the VGH had a ~5 KOhm resistance against ground. I cut the VGH trace on the left panel PCB to the Panel and now the TV is no longer going into protection, but shows a picture with a vertical black line and some small horizontal bad lines. Please see the image.
I am a bit surprised, since 5 KOhms do not really seem to be a short.
Obviously now the left (always seen from the back of the TV) part of the panel now has no connection to VGH. I ordered one of those little DC DC convert kits from China to feed in a programmable VGH, but that has not arrived yet. Will that fix that issue ?
I have seen a couple of videos on Youtube for short killers for CKV lines. I guess that should not be done for VGH ?
