Re: Blue Shades

There may be a failure starting on the video or matrix driver boards. This has to be verified at the service center. The fix will be done by swapping in a new board to replace the failing one(s), and re-doing the factory setups to make sure that the default colour temperature and levels are correct.

I suggest that if the set is out of warranty ask for an estimate first.

There is an approximately 3" line of blue light

IS it like the picture is being cut off? You may need to check the connections to your buffer boards and main logic boards.

Blue spots on pictures

there is an adjustment that can be done by an authorized tech, this is not something you can do. it is a voltage adjustment that needs to be done . the panel has now come to full conditioning and needs to have changes to the power that drives it. it gets worse because of the higher voltages that are feeding it.

Blue snowy pixel areas on my plasma

some of these panels were mis-calibrated from the factory after not aging long enough. Let the TV run for atleast 2 hours and adjust the Vs and Vscan voltages. When it is blue in the left I have found generally the Vs is about 10 volts too high.
