I had the same problem with my Lnt4071f. I called tech support and they said it was a faulty panel and the entire set had to be replaced. If you have your warrantly still use it, if not you may just be able to replace the panel, but its expensive.

The horizontal sweep signal to the yoke is bad. Since other problems exist, the problem may be in the IHVT HI voltage transformer area. Check for bad solder around the IHVT pins and yoke plug. I hope this helps. Lee http://www.CrazyComputers.com
