LCD television sets dos'nt have crt's, but ofcourses out of the RGB circuitry, R & B circuitry is'nt working or its not receiving the proper signals, that's the reason you see only green color,

If you are feeding the signal thru DMI/RGB cable from your set-top box, check for cable loose contact, cable wear-out, if you are feeding the signal thru coaxial cable its problem within the TV's circuitry.

Green tint


Go to a channel that is in black and white and turn color all the way off.

Screen should be a black and white or gray color.

If green there is a fairly easy way to adjust--let me know what you find and I will tell you how to attempt the adjustments.

The screen has a reddish tint to it. Seems like a color issue and not sure what to replace. The picture works fine but everyone is red. Not sure if there is a bulb to replace or what? Any suggestions? This...


You need a simple color adjustment. (Color Calibration)

You don't need to spend money on this. Try it for yourself.

Your main problem is that your color temperature is set to warm.
You need to change temperature to COOL or 6500K depending, on how it is labeled.

You will see improvement, but there is a little more...
Move "Color" DOWN from it's current position (probably at 50) to somewhere between 30 and 40. (Just a couple of clicks above where the color rapidly washes out.)

At this point there will still be slightly unnatural color to skin tones, but all the artificial "sunburn" and blaring red will be gone.

Last (as far as color goes) move the tint 2 to 4 clicks toward green. This added green tint balances the color so that the flesh tones become completely accurate and realistic.

For even better detail, continue your home calibration here:

Images on screen are very red. Tried adjusting everything in the menu but still every thing is like glowing red.


Color balance is labeled "Tint"
Color amount is labeled "Color"

Both are in the "picture" adjustments menu.

Either your tint is swung too far to red, or the color setting is wide open making normally pink faces look sunburned...likely it's a combination of the two; Too much red, and a bit too much color.

Going back to the "default factory setting" in "setup" will also drop all settings to center.

Have a green tint over 90% ot the center of the screen


I had the same problem with my 60V500A about a year ago. The screen got a red tint in the center and the image was fuzzy in that area. A new lamp didn't solve the problem. I did some checking and found out that the original light engine used in this model had a cooling issue that could cause the light engine to overheat and distort the LCD panels. My warranty had run out more than a year before this happened so I figured I was screwed since the light engine was so expensive. I decided to call Hitachi tech support and see if I could get a discount on the cost of a new light engine since the cooling problem was a known issue for this model TV. I calmly explained to them that I was aware of the cooling issue in the light engine and that I felt like a $4000 TV should last more than two or three years. Tech support gave me the phone number for my local authorized Hitachi service center and I gave them a call. Once the technician confirmed that it was the light engine that was the problem Hitachi sent him a replacement light engine at no cost to me. I was WAY past my warranty period so I still had to pay for the labor to replace the light engine. $300 for labor was a lot cheaper than buying a new light engine or tossing the TV and buying a new one. I have to say that Hitachi earned my respect for admitting there was a problem and doing what was needed to correct the problem more than a year after my warranty had expired.

Hitachi 52 projection tv


use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
