Stduo 1737 DISPLAY

Hello guys.
Today I received Studio 1737 for my father.
And I want to share how dissapointed I'm.

First I'm in Bulgaria (small country in Europa).
I brought it from official dell distributor named "IndexBg"
First they told me 'I must wain 20 days max for it and It will be made in Ireland.'
Instead I had to wait around 30 working days, plus I can see clearly on the back side of my laptop "Made in Poland".
Poland is not Ireland right!

But it is still Ok no problem.
Now:
1.after i start the lappy one key from media pannel freeze constantly on and the media pannel not working at all.
2.The screen is horrible.
It is MONITOR\SEC5442 (I guess as result from Poland factory, because my Studio 1535 is made in Ireland and it has great LGP LED SCREEN).

The white colour on my Studio 1737 acctually is more yellow than white.
And difference between my Studio 1535 screen and this one is like day and night.
Oh and on the lowest bright level, the screen clearly pulsate or vibrate very strange.

What I can do?
My country is small, the companies are not very friendly with clients....
Plus my father has work and He must work on his new laptop.
He has no time, and here the companies very rarely replace notebooks or give money back.

Suggestions please.
And What I can do with this crappy SEC display, it is really....
I will post pictures later if I can.

Greets,
Zdravko
