i am technician the advise i give here is only for wih out any responsiblity, this is only for technicians who know how repair lcd monitor in safe and controled enviromen, user or noon technician donot use at home, danger involves.
The samsung monitor 740n has 85 deg cap at c301 ,c311, c312 all 820 uf 25 v and fuse resistor of 3 amp r401 they all fail monitor does not work since there is to voltage to invertors. replace all the above with
1000 uf 25v 105 deg, replace them all and the fuse resistor too, it should work resolder dry joints. it is advise to change all caps if possible.
