Question about Samsung SyncMaster 740N 17" LCD Monitor
3 capacitors (820 uF) deformed, fuse 301 dead (probably 3A) and sc on C 231 (5,2 uF - probably). changed the 3 capacitors with 1000 uF, but 3 A fuse burned again. still have a black screen. any idea or a power supply diagram can help. thanks!
I would check all the transistors (especially the larger ones) for shorts. If you can separate the power supply from the other circuits (such as by unplugging a connector to other boards), I would do this and see if the fuse still blows. If it doesn't, then the trouble is in another area, perhaps the LCD driver circuits.
