A Gateway FPD2275W was dropped of at the shop with the complaint of no video just a black screen, started out with the video going dim until eventually the monitor turned on with the black screen only. Immediately I suspect the PSU or inverter board. After opening the monitor which is usually the most difficult part of repairing LCD monitors, I could immediately see a puffed and vented electrolytic capacitor with a value of 1000uF @25 volts, location C862 on the voltage supply line to the inverter circuitry. I checked the rest of the capacitors on the PSU/Inverter board with an ESR meter and they were all well within tolerance. I did find some questionable solder connections while looking over the board with my optic visors and re-soldered them. After replacing the capacitor and reassembling the monitor, it worked great once again.
FPD2275W , turns on with black screen, repaired.
