Hello, I'm sorry to tell you that that set has a bad optical assembly. The blue part has gone bad and cause's either a yellowing of the screen or blue spotting or both. You can purchase a new lcd tv cheaper than you can repair that one. Do not replace the lamp, it's not what's wrong with it, and you'll just waist your money. thanks, Terry

You have a bad optical engine or sometimes called a light engine. One or more of the LCD panels is failing due to heat build up (a faulty design on these sets). Anyway the part runs around 500-600 hundred dollars not including labor. You will spend more money to fix than what this set is worth sorry to say.

I have vertical stripes (yellow, clear, blue then green) covering my entire screen. I have a Hitachi 50v720 HD tv. Help anyone?

T.V may have been magnified. Something magnetic too close to television will fry the screen per say. There are repair people with demagnifiers but doesn't always work

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.

The light engine will need to be replaced. Without a warranty the part is very costly. You are lucky...
