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!
Sounds like the light engine is going bad...that's why they stopped making these rear projection sets using LCD's. Costs almost as much as a new set! But get a second opinion before trashing it.
Go to the Zenith repair site. This has been resolved in a lawsuit. Zenith will fix it free of charge through 7/1/2010. The shop just picked my up to replace the light engine free of charge. Call 1-800-228-1757, have your model number and serial number, and where you purchased it. Here's the neat thing-the question I asked is "have they fixed the problem with the light engine, or is it going to keep going bad?" If happens again (blue lines/spots) before 7/1/2010, they'll replace the TV with a new and different TV of equal value!
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
Wow, 3 in a row. As described on 2 other projector issues this is very similar to those others. I'll repeat the info here.
I assume this is an LCD. I don't remember the s4 being a DLP projector.
This
sounds like the LCD panel used for the blue color has gone out. The
image is made up of red, green and blue images layered upon the screen.
If the blue panel has gone out then there is nothing filtering out the
red light in the image.
It looks like yours has just a secone of the panel dying or comming loose from it's connector.
It
could be a simple open and reconnect fix. I personally have never
opened a projector, so I'm not going to walk you through it as I do not
know how hard it would be to tinker with. It should eb a cheap fix for
a true repair man though.
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.
