Monitor does not turn on


The most common cause of power issues with that model is a dead power supply resulting from a failure in the capacitors on the power board. This is a very easy repair. You have to replace the 6 filter capacitors on the power supply board. The capacitors on the power supply board should be flat on the top and when they fail the tops will bulge showing failure. You can open the monitor up and look at the power supply board and check for the bad capacitors to verify the failure point. Here is a link to some information and parts kit to repair that board.

My dell GX 1 optiplex pc is not powerring and power supply is not


Hi:
If you don't have the LED lit up on the board, the most likely failure is your power supply. You should be able to get a computer store to test it, to be sure, but a replacement is $30-40

My Compaq Presario will not start since we had a power failure in our town yesterday. It seems like it is unplugged, but it is plugged in. Can you help?


Can you check if the power is connected to the ac outlet, and if the cpu has a power. If no power in the cpu even the power cord is pluuged in the outlet of the power source the problem is your power supply. Maybe the fuse blow up when the power is back after the power failure. But sometimes the cpu has no power but the monitor have a power it's also power supply failure the dc output of power supply is not working. the best solution is to replace the power supply with the same wattages or higher.
