LG flatron L1970 h monitor flickers.

LG flatron L1970 h pc monitor flickers. what di i need to exchange to make it function properly again ? (the pc is ok. it has monitor problems with other monitor, so problem of monitor flickering is with the LG monitor.
i am skilled in elctronics. can i fit any replaacemnet parts myself, or can this only be fixed at the factory ?
does it make sense to ship it and get it repaired out of home, costwise, when compared with buying a new monitor ?
