T con board issues.

broken pins/ wiring of the signal cable. Is there blue screen when
there is no input ? Try to change your signal cable.

Hi

Thanks for using FixYa. Usually this happens when the Light Engine has gone bad, and I should say this is a common issue with Projection TVs. There are three tubes/mini LCDs inside your TV- green/yellow, blue and red. When the set heats up over time of usage the screens tend to break resulting in leaking color everywhere. The cost to get this fixed by a professional should be around $300 depending on the parts that needs to be replaced. Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks

HI, Check the menu set up of the TV. There should be an alignment feature that aligns the blue, red, and green colour projectors. If the blue is out of alignment that is likely why you can see it on the dark backgrounds. The set up normally puts a white cross on the screen and you select each of these colours and then move the cross over the white on with the arrows on your remote. Once all are aligned correctly you shouldn't be able to distinguish between different colours and hopefully this should get rid of your blue shade.

one of the color guns has failed there are 3 RED BLUE GREEN So red and blue make brown theres how it becomes sepia in color
