I have an elusive problem with my 4665. It powers on fine and the screen comes on. However, when it first comes on there is a ghosting of the image, especially across the upper half. For instance, the HDMI label shows where it should in the upper left corner and then a stretched out ghost image of that same label appears offset down a bit. After about 20-30 minutes the picture clears up so it seems that something is heating up enough to warm up and make proper contact. I also found that I can cause it to be "fixed" if I slightly flex the entire TV, especially with the back cover off when it will flex and twist more easily. I just don't know which board or connector would cause the ghosting effect. I don't know if it is something in the panel itself, a connector, a wire, a board, etc. Also, it does it with two different power supply boards and two different sus boards. The backlights work perfectly. If anyone has thoughts on where I might start it would be must appreciated. What the heck would tell the panel to display that image in a different place than it is suppose to be displayed and about 4 times stretched vertically but then clear up with time/heat/expansion? Thanks.
