LCD Rear Project TV has yellow tint, replaced blub, still yellow
I have a 5 year old 50' Hitachi's LCD Rear projector tv, all of a sudden the screen has a yellow tint and tends to be on the dark side. The owners manual states that could be related to the blub, so I replaced it, still have the same issue. Any thoughts what might be the issue?
Re: LCD Rear Project TV has yellow tint, replaced blub,...
Sounds like you have a faulty VGA cable. Best replace it as one or more internal wires could be damaged. I had similar fault, when the cable was moved it went from yellow tint back to clear image, or back to yellow.
As for a dark image, if changing the lamp unit didn't help try cleaning the mirrors

I have the same tv and the same problem, but my yellow is a cloud around the outside of the screen. My tv was recently moved, and a repair shop told me that sometimes in a move these tvs light engine takes a shock and causes a yellow "band" on the screen. I am hearing that these light engines are not cheap either. Hope this helps you.
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.
Depends on whether you use the TV as your "daily driver" or not. Colour patches on the edges of the screen sounds a bit like a purity problem. If replacing the lamp every year is proving too expensive, not to mention a tad repetitive since it indicates the short life of the lamp(s), plus the set happens to be a few years old, perhaps consider a new TV of approximately the same screen size (50" and up) - if the latter is what you want to do.
