Just Repaired A BenQ FP731 17″ LCD Monitor
This LCD monitor was repaired before by a monitor repairer from other company. I found he had touched (solder marked) on all the inverter area such high voltage transformer, inverter ic, push pull transistors (C5707) and the buck royer p-channel FET FU9024N. The complaint for this LCD is display came out for a while and then shut down. After scanned thru some of the major components i did not find anything wrong with the inverter board.
Suddenly i recalled there was a case of pico fuse turned into higher ohm instead of open circuit. I checked the pico fuse with my meter and found that it did show about few ohms, by right it should have registered zero ohm! Replacing only the fuse solved the display shutdown problem in this BenQ fp731 LCD Monitor. I guess the monitor repairer might have missed the fuse because he may have though that the fuse have ohm reading means it is good.
This experience reminds you that when you want to measure the pico fuse, make sure you get zero ohm otherwise replace the fuse and retest again. If you want to learn more about LCD Monitor repair please go to my website at http://www.LCD-Monitor-Repair.com
