How exactly did you identify that the platters are stuck?
What exactly do you mean that the drive starts after you changed the board?

To put it simply, if you're inexperienced with DR and platters are stuck and you try to move them yourself, it is game over. If you care about data, you can do DIY, but you have to accept the consequences too.

PS. I don't know about others but i would appreciate if you don't use red color on your post. Thanks.

The platters are not stucked, but I notice that there are no gap between each platter, it means that all the platters are pasted to each other. When I insert the new board, I heard a clicking sound inside the Hard drive which made me to think that the board suits my HDD.

I mean no offense, but you do not have any ideas about what you are doing and if data is important there is realisticalyl one option - send to a professional and hope your repair attempts has not made things worse.

I'll try a professional, because the data is worth spending.... Thanks for your advice
