there is a shop in first or 2nd floor of Singapore plaza who has all these LCDs stuff and even touch panels. I bought form my Asus Memopad touch panelfor 2200 from him, fitted myself. Samsung 8.0 lcd might be for 3-4k. note more than that.
Theres another shop in basement of mobile plaza next to Zong headoffice on Bank Road saddar. He also repairs Tablets. Took 1400 from me for a Samsung tab 3 8.0 just like yours which wasnt turning on. dont know what he did but he said typical of shops wala "IC jal gai thi". But tab working fine afterwards.
