Solution for the Hitachi 50V715. I contacted Hitachi and they told me there is a problem with the color engine with this and other Hitachi models. They will replace the part for free, but first I need to take it to a repair shop to verify the problem and I have to pay labor. Not too bad considering the cost of the engine.

Hiya,

I had the same problem with my LG LCD when connecting through component cables. I eventually managed to resolve it by using the hidden calibration menu for my LG tv. This menu is for AV technicians and also has options for limiting tv channels for hotel rooms etc.. Most importantly for me and you is that it has Red, Green, and Blue offset and gain levels so that you can adjust the picture colour levels. The way to access this menu differs from model to model but often requires pressing a combination of menu buttons for a few seconds.

BE WARNED THOUGH: THESE MENUS ARE VERY COMPLICATED AND WRONGLY ADJUSTING THESE OPTIONS CAN SERIOUSLY SCREW UP YOUR TV AND INVALIDATE YOUR WARRANTY!!!!

IF YOUR TV IS UNDER WARRANTY GET IT DONE PROFESSIONALLY!!

OR CONSIDER PAYING AN A.V. TECHNICIAN TO DO IT FOR YOU.

If you are fairly technically minded and you don't have a gaurantee then consider using these options.

1. Make sure you are on the input channel you need to adjust e.g. AV1, Component, HDMI

2. Press and hold the 'magic buttons' until menu appears.

3. Find the right option. On my LG it is 'ScalerADC'

4. Make a note of all values before adjusting them so you know how to reset them.

5. Red / Green / Blue Offset= Adjusts the saturation of each colour in the tv image.
Red / Green / Blue Gain= As far as I can tell, adjusts the hue of bright sections of the screen.
There are usually contrast and brightness options also.

I recommend having some kind of static, well balanced image on the screen while adjusting these options so you can see the results. A paused DVD scene is good, for example.

As for the 'magic buttons' to press, you'll have to try Googling your model.

I have noticed on my TV that when different resolutions are inputed through my component channel I seem to get different RGB levels. I've adjusted it suit my xbox 360 at 720p, but when I play DVD through it at 578p then the RGB levels come up all wrong again.


Anyway, hope this helps.

AGAIN, BE VERY CAREFULL WITH THESE SETTINGS.

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.

This is what you're going to do, Turn on the Tv and go to the service manual, if the green tint is still there, you have a defective dmd board, but if it's no there, then you have an issue with your video board

Greenish yellowish tint on the tv


I have been advised that the color/light engine of the TV fails often and will typically create a green tint on this unit. I have one on order to get a replacement installed. BTW, it is not "user serviceable" and (for me) will require moving the TV to the repair shop for the change-out.
