Portions of my screen are blue - I am still able to view the entire screen and programs, but there remains a blue section which has grown in size over the last few months. what might the trouble be?
This is a set made by LG who is also Zenith.
This model has a well known history of the optical light engine being burnt which causes the blue to be present in certain parts of the picture.
The lamp shines a very bright light into the L shaped optical light engine---there are lens and partitions inside--blue, green and red and the blue is closest to the lamp and the heat.
There are also at least 2 or more versions of the optical light engine used in this model.
If you do not have an extended warranty----it will cost too much to repair---last one I saw over a year ago the engine sold for over 600 exchange, not counting major labor to replace it.
I do not enjoy giving bad news but I have seen over two dozen sets with the same model number and same problem.
If this told you something you did not know rate this solution as very helpful as I do this here for free--I am 100% sure it is the Optical light engine....
Sorry to give you bad news.
REGARDS, SD TECH
