Question about Emprex LM2201 22" LCD Monitor
Hi, i don't know the exact power board you speak of, most fuses for power supply protect ac inboard power, and backlights. if backlight inverters touch ground or ground out, this will blow fuse. otherwise, the fused circuit is used for main inboard power going to primary capacitor. take an automotive fuse holder and solder test leads long enough to work with, install 4 amp blade fuse and jumper/solder the circuit to the fuse on the board and power on the monitor. if all goes well, probably just power surge or outlet grounded. if blows fuse, check to board for obvious burns or blown capacitors. if not there, unplug backlights and power on, if still blows, check to make sure no direct conact with board and back of screen. just be thorough about looking carefully for shorts if there is one. and don't forget to replace the factory fuse on the board with the correct one after you finish repairing, don't leave that automotive fuse in. good luck.
