i think is the blue mirror in side the tv...it has 4 mirrors inside

This is normal and is a color calibration issue.

For correct color, NEVER use the "WARM" setting. Why? Too red. You cannot get REALISTIC or ACCURATE color using the "Warm" setting.

Since we are speaking of Samsung, first avoid the "Flesh Tone" adjustment. When things are set correctly there is no need for this adjustment. It is a quick fix and not for the "discerning eye".

1. First, access the "Color Temperature" menu. From here select "Cool2" or the coolest temperature setting.

Note: For Samsung use "Cool2", or if not available, "Cool1". Samsung has inadvertently increased calibration confusion by issueing TVs that have just "Cool1", and TVs that have both "Cool1" and "Cool2" :0[

For other brands, use "Cool", or "High", or "+6500k". Anything lower artificially reddens the picture and compromises detail.

2. Now return to the color settings and reduce "Color" to between 30 and 40 (on a 100 scale). The sweet spot is just near the place where the color rapidly washes out.

3. To round out the color palette, move to the "Tint" adjustment and ADD a couple (3-5) clicks to the GREEN.

Adding the touch of green is what is needed to take out the last bit of "pink" and will make all the tones and all colors display properly.

I hope this helps!

The color signal consists of Red, Green and Blue. Those three colors, at various degrees, make all the other colors on your screen.

If you have a BRIGHT green screen it's best you don't operate your set.
If it's just tinted green then there is a problem on the CRT (Cathode Ray Tube) drive board. Do check your "tint" setting and see if someone misadjusted it. If that isn't it then you need to have your set on an electronics bench and get an estimate for repair.

adjust the blue bias on the high voltage block .
it has focus and bias for all three colors

I encountered the same problem with a color computer monitor several years ago. Everything went green. The repair techies told me that's a sign that the power supply is going bad. You will not be able to adjust the color. You will have to either fix it or replace it. Hope this isn't a common problem with this model Samsung TV.

If the whole screen has this tint problem, there is nothing you can do. It must be repaired. You will need to take it in for service.

try a DVI/digital cable on the HDMI inputs
