Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!
The machine is still under warranty from samsung so I would call 1-800-samsung to find the nearest service center. Problem could be caused by a bad main board, bad lvds cable or a defective t/con board or lcd panel.
A vertical line means the line is up and down in the middle of the screen. That would indicate that the vertical IC and the surrounding components are working perfectly. A vertical line as described is the result of a lack of horizontal deflection (to move the beam from side to side) Since the high voltage is obviously OK, the problem is most likely a bad solder connection in the horizontal yoke circuit. Examine the bottom of the PC board in the area of the flyback transformer, and yoke connector (has four wires Red, Blue, Green, Yellow).and the pincousion coils, capacitors, etc in between. Flexing the board in that area may cause the problem to come and go. Resulting arcing should also be visible. BE CAREFUL, as hazardous voltages are present in the circuit!
the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
you need to replace both convergence ICs they are STK392-110 you can get replacements at the following link with free installation instructions so you can do the repair yourself. http://servicemanuals.vstore.ca/

A1: There are 12 models in total: KDP57XBR2, KDP65XBR2, KP46WT500, KP51HW40, KP51WS500, KP57HW40, KP57WS500, KP57WV600, KP57WV700, KP65WS500, KP65WV600 and KP65WV700.
a bright thin line in centre is called horizontal line.
first of all do not keep tv on unless it is rectified.
If you want to put on tv keep brightness minimum to protect your screen for any demage.
your problem is in vertical section.
1 check vertical supply.
2 check parts in vertical section or loose contact.
3 yoke connrctor loose
4 ic defective
It is not serious problem can be rectified easily
maybe on your remote press menu and find converence and use the keys to move the red first over the green then move the blue over the yellow ..by standing back and just using the remote....should end up with white lines.
and dont hit that button again once set.
a tech should do this quickly and charge you minium.
