Yellow Haze Center Screen

If the red haze is not convergence---that requires parts.

The set has three picture tubes---with set unplugged and back cover removed clean the three large lens that are topside---as for the red haze a quick way to know what is wrong is with set on turn the color to zero----what color is the screen? Should be black and white--if red to some degree tracking or screen controls may need adjusting inside the set---Yellow picture in that situation is a different issue.

Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

I have a Hitachi Ultravision. 55VS69A. It has worked wonders but now there is a blue screen in the center of the tv. Should I just replace the bulb. thank you.

The light engine in your set has gone belly up. It is a very expensive repair. Good news is that on a whole bunch of models like yours Sony has extended the waranty on the light engine. Check with a local authorized Sony service center and give them the model & serial number and you might get a free ride. If I were a betting man I'd take odds on 'you're in luck'. LOL

how to fix my problem Blue haze/cloud in center of screen, slowly spreading .but last time my lamp broken I order by my self and fixed now I have the blue color in my screen please let me know what is the problem may be I need to replaced same parts please let me know how to fix thank you

The yellow haze is the result of the blue polarizer burnt-in, you will find it sitting in front of the dlp chip.

I have the same problem with blue haze that just spread out on model 55VS69A ,
tv is almost 2 years old. i called hitachi and they advised to call a local repair center to check the tv...they confirmed Optical Block (light engine ) replacement light engine cost $1400 and labour $400, so i called back hitachi and they said they will provide light engine and will have to pay labour!....this is not right paying out of pocket for a tv less than 2 years old....I am not sure if the issue will resurface again...more likely ....Hitachi is supposed to issue a recall or atleast like sony did to cover all cost for there defective TV's....I will NEVER buy hitach again.

Hitach SUCKS.

The blue filter is burnt out. A very common problem in Zenith DLPs. There are 3 color filters, 1 blue (a pinkish color), 1 green (a grayish brown) and 1 red (it is red) they give you your colors for you picture. This is a simple fix.

possibly cleaning of the lens and the mirror might improve the picture. it could be what is termed a glycol or fliuid issue. dirty glycol will cause this yellow halo effect. the glycol came be changed a rather expensive and evovled repair i think

Typically caused by a defective light engine. Part is over $1000 last time I checked on it. Could also be caused by a bad "digital board". I've seen this symptom more than once on this set.
