Samsung Syncmaster 906BW, LS19MEWSFY/XAA LCD monitor came into the shop today with no picture(really it was that the back lights were not lighting). Upon opening the monitor and removing the SMPS/Inverter PCB, I noticed 2 puffed and vented electrolytic capacitors right away. I checked all the rest of the electrolytic capacitors in the SMPS with my ESR meter to make sure no others were bad and they all were within tolerance for both ESR and capacitance. I scanned the SMPS for bad solder connections and found none. Next I removed the 2 1000uF @10V electrolytic capacitors that were puffed at locations C109 and C110 and replaced them with 2 1000uF @25V electrolytic capacitors with a 125 degree Celsius temperature rating(not necessary to go up in temp. and voltage rating this much or at all but don't use anything less than the originals). After reassembling the monitor and turning the monitor on, it worked like new.
