Blue haze and dull yellow patches on screen

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

I changed the LCD lamp, but there is still a yellow haze.

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

Blue haze spot-yellow tint

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.

Yellow and blue on screen

I am slightly confused about the model of the television, because a 46F500 is a rear projection set that doesn't have a lamp. It has 3 picture tubes and I have a few of them in my shop right now that have the problem you reported. What we do to this set when it develops a convergence issue is to check each resistor around the convergence chips for discoloration, and replace any of them that have changed in value, along with the STK392-150 ic's. If you don't have an ohm meter and solder/desolder equiptment, you can usually get a shop to do this repair for 150.00 to 350.00. Parts will be 50.00 and labor , the rest, depending on the quality of repair shop that you use. Good luck, Russmann.

Hitachi 60 in. 60V715 Yellow Haze

I would first check and see if any software updates are out on this set, you can call Hitachi, if not that then it could be the engine assemble having problems.

Yellow haze in center of screen

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.
