There is a permanent red tint (haze) over the center (4:3 aspect ratio area) of my Hitachi 51F510 screen. I mainly notice it when watching HD channels since the edge of the tint lies where the edge of the side bars normally are when watching SD channels. Any help/advice would be appraciated.

Hi: You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.
My 43fdx20b had a pink tint to it also. The picture was clear otherwise. I found, on mine, I needed to adjust the Red Screen control. It was located behind the front panel. I removed the two screws on either side of the front panel and was able to remove the panel. Then I adjusted the Red Screen control. I found that if I tuned in an old Black and white movie I could adjust the color fairly accurately. Good Luck.
If you have RED color that starts from Center of the Screen,(no red color on sides ) 100 % your light engine is deffective..
In order to solve this issue Replace Light Engine Control Board (also called Driver Board ) attached to light engine.
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.
