It seems my problem may be with popped capacitators on the powerboard. Does anyone have an opinon on this potential solution?
Recently, when I turn on my LN40A630, for the first 20 minutes of having the TV on, there will be 3 horizontal lines evenly spaced across the TV, and on the right half of the TV the picture has a shadow effect and "smears" the image across the screen. Then after it has warmed up, the picture will just fix itself all of a sudden, and the screen will appear fine.
When I leave the TV off for more than a few minutes, the TV will go back to having the lines across the screen, and will take another 20 minutes to fix itself. I've moved from component to HDMI cables - so I know that isn't an issue, and I've had previous LCDs hooked up to this same outlet and cable box, so I don't think that's the issue.
Has anyone had a similar problem? Any suggestions for me to try? The smear appears on all the inputs, so I know it's the TV, but it's so wierd how it fixes itself. I have the screen SQ01, for those who are curious.
If I can post pictures, I have them, and will - it may help to better show the problem.
