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.

Philips tv's have always had this problem. Between the picture tube and focus lens there is a layer of coolant fluid. The coolant fluid, over time, will break down and turn a brownish cloudy color and it usually starts with the blue. Something to do with the color frequency. Have a good repair shop check it out and if the fluid is the problem have them change all the fluid in all 3 picture tubes (there is a red, green and blue tube). Don't feel bad, like I said all the philips projo's had this problem. Thanks

The only time I have had issues like this was because of the Component Cables not being in the right position (the Red and Blue connections switched), or a bad Component Cable where the Blue Connection is not receiving a signal. Swap out the cable to be sure and double check that it is properly installed. Green to Green, Red to Red , Blue to Blue.
Hope this helps,

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.

White colors schemes seem off white color or brownish color and blue has green tint or baby blue color. .

Check the coolant in all three crt's as chances are it is contaminated (should be crystal clear). If brown (beer color), replace coolant in all three crt's and perform convergence adjust. Picture should be like new!!!

Good Luck!!!
