hi. maybe repairable.. maybe not. it could be the
1) lvds cable or
2) fuse or components like transistors on the tcon
3) tcon board itself
4) logic board.
#1 is repairable if got parts, #2 may need to trouble shoot further to know which to replace, #3 unrepairable if tcon connected directly to panel, #4 replace logic board need to check availablity.
