    Having the same EXACT problem on my Samsung LN-S2651D. Samsung gave me a few things to try, then disappeared from further assistance. Wonder if there's a known defect?

The display screen is made of a matrix of elements connected to cables along the side and top. On your unit, some of these many, tiny connections are making contact intermittantly thus losing the elements in that area. These contacts are held in place with just pressure and if that is disturbed, you lose that line of elements. Try squeezing the cabinet of the TV on the outside at the top in the area of the loss and see if that makes a difference. May have to go inside and see if the contact assembly is disturbed or warped or something.
Hope ya fix it!

SOURCE: My SOny Bravia 40 inch LCD TV has a vertical line

Hi,

It could be 1 of 4 things:
1. One of the ribbon cables has worked itself loose (Simple Fix)
2. One of the assembly boards maybe faulty
3. The driver board which feeds the panel maybe faulty
4. The panel is faulty

The driver board in the UK costs approx £70 and approx £35-70 to fit it if this is the fault.

All other parts are between £80-160 and approx £35-70 to fit it if this is the fault.

The panel will cost approx 50-75% of what the TV was worth when you bought it - "Repair versus Replacement"

Thanks

Nothing you can do about that...get used to it or change the TV.
It's a defect in the panel that can't be reliably fixed.

Screen fades to blue.


The Blue SCREEN setting is too high. These adjustments are located inside the TV behind the front panel. There are two screws behind covers and then a wooden panel to remove to access the adjustments. The leftmost set are for BLUE, the middle are GREEN, and the right are RED. The top row are FOCUS and the bottom are SCREEN. Focus will focus/unfocus the tube and Screen will adjust the power of that tube (there are 3 tubes, one for each color). If Screen is adjusted too high, horizontal lines will appear (my TV had red lines, but I played around with the knobs and saw that it could happen on any of the colors). Additionally, if SCREEN is set even higher than that, the tube could go so high that it turns the whole screen that color (in your case, blue). If this happens the TV will shut down, probably due to either overheating or overvolting. To fix this issue, turn the appropriate SCREEN dial down until the lines go away. In your case, you want to turn the lower left dial down. Don't turn it too far down, if you turn it more than necessary the TV can give you an AKB error (noted by the STANDBY light flashing a sequence of 5 blinks).
