Re: blue haze in center of screen yellowish circle

Hi you see alot of these types of tellys with your problem or similar problem and they all lead to the same fault i dont think the problem will be the optic filter the problem is more likely going to be the convergence ic it is best to replace both of them as replacing one usually means youll come across problems with the other sooner or later getting these replaced will put your telly back how it was and youll find that you wont have this problem again for a good while.
Most tv repair shops will have ample experiance in this fault and if you ask them they will tell you the same as i have.
Now if you have the equipment to do this repair yourself then you will need to get the schematics for your telly and any part numbers youll need.
It is also worth checking any resistors as well as often these will go when the convergence ic go this will need testing and replace any as needed.
If you are going to get someone else to do the repair then the cheapest way is for you to take the telly to them as you will get charged for call out and for transporting your telly so to avoid this unecessary charge take it their yourself.
Let me know if you need further assistance ok

White has turned pinkish

sounds like the linear adjustment is out of whack.....most projection type tvs, projection, lcd, plasma, have to be correctly aligned so that the color grids overlap each other to properly display the correct hue being created. you'd need the service code to re-adjust it, or have it serviced. also possible that one of the color grids is bad, but if you have all three (red,blue,green) colors showing on the entire screen area i would doubt it

Blue Haze in middle of screen progressively getting larger

This one is easy. WHen this happened to me, I simply called GE extended warranty service up and bought an extended warranty. I waited 30 days and called them up with my problem. A repair man showed up a few days later with the 1200 dollar light engine and installed it and left. Then I called GE up and cancelled the warranty. Total cost?: 48 bucks

Blue haze on hitachi 51" tv

I finally emailed Hitachi about the blue haze and since my televison is only 16 months old they agreed to pay for the part (they didn't say what part) and I will have to pay the service charge. The repairman is coming out on 2 Apr 08. I will post results after that.

Blue area near center of screen

Uh Oh! blue screen of death. Your light engine has warped a little from overheating and is distorting the picture.

My suggestion to you is to get on the phone with hitachi and start complaining, then keep complaining until they agree to pay for it. You may have to get the problem diagnosed by a pro before they agree to pay for it though.
