VU 32K160 Rev D 32" LED TV color problem - tint issue?

Hi, I can't find a proper section to post this so moderators please move it to most appropriate section if its in right place. Now coming to my problem. I have just purchased VU 32K160 Rev 32" LED TV at very cheap rate from flipkart (~15K) and TV is beautiful as well as works but only problem I am facing that colors are not accurate, specially human skin colors have some kind of TINT . So I tried to adjust settings and colors, I can change all settings under picture but TINT feature is grayed out. It means I can not adjust it .

Please advice how can fix it, I think skin color tone is due to improper hue and saturation settings and I can't understand why on the earth they have disabled TINT adjustment feature even if its there . Why VU you would do that ?

I already made a hard decision by buying not so common brand or relatively lesser known brand and now this.. its totally shit. Advice please.
