Macbook pro - Display flickering stripes

Question

Hello,
i'm having, again, an issue with my macbook pro 17' mid 2010.
This is my story
I bought it in July 2010, it worked fine until one month after the end of the one year warranty period (shouldn't be two years in Europe?).
I don't remember if it was on sleep or power off but that day three bands appeared in the middle of the screen:
One is more or less 1cm , colored and flickering, next an half cm white one sometimes flickering with a green tone and, last, another 1 cm colored and flickering.
I called apple explaining my problem they said they cannot do anything as my warranty period was expired and they gave a contact for an authorized apple service in my area.
I went there, they asked me 50€ (living in France…) only to take in charge my mac plus, in case, additional costs.
I accepted,   after one week it was repaired at no additional fees (as they were an authorized apple service I get three additional months of warranty).
I’ve asked them what was (apparently a software problem…) the problem and how they solved they answered me something like “it’s a secret”.
Mac was working, fee was acceptable , I didn’t care about the answer and I went home.
After 5/6 months problems – as usual… just after the warranty period - come out once again. I don’t remember what it did, for sure the usual PRAM reset, SMC etc. and I solved the issue by myself without paying other 50€ for “the secret”. At least I thought the problem was solved…
Past week, after one year of good behave problems appeared again restarting from sleeping… this time no way to solve the issue.
I ran all the usual tests, reset everything, reinstalled from a previous time machine , also found ASD and used it (hope no one blame me for this… as you can understand I’m little bit upset) running it several time from OS and EFI. No problem found.
External monitor through HDMI works perfectly, print screen doesn’t show the stripes… shouldn’t be an nvidia issue.
I got an appointment next week with “genius” and if they are going to run ASD they won’t find anything wrong and, reading other messages here in the board, solution will be “replace LCD or  Logic Board. 600€ to the counter please.”
3000€ (when I bought it I went for I7 core… and additional ram) for a pc giving me headache after one year … is not the quality I was in habit with Apple.
Let’s see… but, before to go there do you have any suggestion on additional check I could perform? I know there was a known problem with nvidia but mid 2010 has GT330m that is not the same model apple confirms having problem (and by the way, I had no freeze. OS starts without any problems)
Additional info, mac never moves from my flat desk. I’m a kind of maniac… never had a shock, no hot temperature…
Any suggestion (even “take a long breathe and calm down” ) is more than welcome.
Thanks in advance
