Hate to tell you this but it sounds like your picture module is going bad. The bluish tint tells me it is leaking to the outside. Some problems with the LCD picture module can be fixed but I never had to fix one. Might check out some videos on repairing LCD picture tubes on YouTube.

Spots in screen is commonly caused by defective LCD on the optical assembly. LCD replacement is very difficult. I suggest to contact the nearest service center at your area.
They might be a problem with the video section(video card)this is where picture is generated and need to be checked there is a possibilty of a chip getting or has a leak .
The bulb gets voltage from this card so pls check it .
