Thanks Jeff for you comment. I have tested all capacitors and resolder connections on the power supply board. I will change a few capacitors to be on the safe side. It was my thought also that these just do run rediculously warm. The picture seems to look good, even after running one-half hour. I will run it longer later today and if nothing fails send it out.
