I have an ASUS VH222H. When plugged in there is no activity on the power LED. It doesn't light up at all. Because the monitor doesn't turn on, well, there is nothing on the screen. None of the capacitors are blown. I'm not really sure what needs to be fixed on the Power Board now. Any ideas?
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

1. Disconnect the cable running to the signal card.
2. Fasten the power supply in place temporarily with at least two screws, one of which is through the grounding clip I circled in black.
3. Plug in the AC power cord.
4. Set your DMM to the 1000V DC scale and measure the voltage across the pins of the large cap (circled in red). Report that voltage.
5. If the voltage measured above is about 1.4 x line voltage, the fuse is good.
6. Set your DMM to the 20 VDC range and measure the voltage on each pin of the output connector. Use the mounting screw circled in black as the ground point. Report those voltages
If you read 5V on any of the pins of the output connector attach a picture of the signal card to your next post.
