My screen has little dots appearing sometimes red sometimes blues behind the picture i just replaced the lamp bulb as i thought it would cure the problem


the projection tube needs to be adjust for color alignment, each tube (red, green, blue) must be aligned so you there would be no color smear appear on screen. if it is aligned try to set up the color balance, hue etc.

Blue hue on left side and tiny blue dots on most of screen. The dots seem to dissapear and reappear if you look closely. I changed bulb about two months ago and it seemed to just get worse since then.


The blue hue on the side and dots are most likely a damaged (burnt light or optical light engine).

This is very common and you may want to contact Sony as there were programs for some models even if OUT OF WARRANTY.


The lamp in the set shines into a a L shaped engine with baffles and lens (red, green, and blue segments) and Blue is closest to the heat from the lamp and usually is the first place to get this type of damage.

I do not enjoy giving bad news but this is what I am sure is your problem.

This model also has a paper filter for the Optic block that should be changed. No one ever said anything about it. shortens the life of the optic block if not changed.

Bad light engine I think


I had the same sort of idea..bad color engine.Hitachi paid for upgraded replacement 'cause they had had so many similar problems with this model. My warrenty had expired so they did save me about $1200 but I was stuck with the labour cost approx $300...

Blue hue on screen


Probably the optics block. It needs to be replaced.

However, it looks like you're in luck. Sony will reimburse you.

Kf-42610 blue hue and blue dots on screen


Hi Guys

The Blue dots or discolouration you are seeing is due too the Blue LCD screen having cracked from excessive heat. This normally happens when you have a power failure while the Television was on. This obviously because the Blue LCD sits next to the lamp - the main cause of heat. The correct part number on the 60" is A-1086-952-A. It is very, very ,expensive.

Sorry to have been the bearer of bad news. Good luck : )
