[Resolved]  Samsung Sgh J600 — Slick problem

I was using this samsung model. But it got stucked on day and was flickering. Now it stopped working. I went to nearest mobile show room they said that the string for sliding is went off. What can i do for this? How can i make my mobile to work... Do i get the original part of this mode, if so were. Let me know if any place either in Trichy or Delhi.. Expecting the response...
