TV - Sony KVM31 Lost Vertical Lock
The above TV is about 12 years old and looks like it lost vertical lock . A jagged vertical line slowly scrolls left and color is intermittent. It occurred when the table TV was on was bumped slightly. Tapping all around the set case for intermittent connections found nothing. As for my experience, I have repaired 1 older TV in the past, have mid-level electronics repair skills and have a DVM and soldering station.
