What does it mean by dead cells?


I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

Blue section (corner) and blue dots


This set has no internal manual adjustments for color. The Tracking or B&W balance is accessed via the service menu. I don't suggest you attempt to adjust without instrumentation. the trouble with your set is not an adjustment. Most likely the Optics are at fault. This model has had issues with filters in the optics being destroyed over time by the lamp. The blue haze will get worse and continue to grow over the whole picture. The only option is to remove the Optics (light engine) and sent it out to be rebuilt.

Blue section (corner) and blue dots


Hey there Aleman500-

I had this exact same issue with mine. Started noticing the "blue cloud" on the bottom portion of the screen.

Please follow this link and the instructions listed. I opted for an "upgrade" that was offered (brand new 46" bravia lcd) but sony had also offered to fix my tv for free.

Two blue dots on the screen


its sounds like the guns has burnt your yube, when switching of does your tv show a bright circle in the middel, or while watching. Smack your tv on the side while on see if the picture goes away or make a bright circle in the middel, this is caused by a bad solder joint but you wont get rid of the bunt pixels sorry.

Green and Blue spots on screen


Sounds like stuck pixels, you really can't fix that. Do some google research if you are curious what a stuck pixel is.
