Need some guidance from the experts here. This is the second Samsung plasma that I've received with the same symptoms. The color bars show the worst of the condition. There is also image retention as well. All voltages are within .2v of the panel label. I have checked all the FET's on the heatsinks and surface mounts as well as diodes. No issues. I also have inspected all boards with a magnifying lens and bright light and have found nothing obvious. I've also cooled and heated all three boards with a hair dryer and cooling spray with no results. This model has a combo Y-main and buffer board, a power supply/ X-main combo board and a combo main/ logic board. I don't have a oscilloscope but have a in circuit ESD cap tester on the way. I'm wondering if this is the symptom of a bad panel? Any suggestions would be greatly appreciated.
