Power supplies generate various voltages needed by the device. The pilot light or red lamp is usually powered by the low voltage, amperage part of the supply which might still be functioning but the high juice sections necessary for operation are fubar. Basically the red light just tells you that the PS is receiving power. It is not an indicator of "good."

it is better to use the old power supply because it is compatible to your mother board

Hello, I have to same problem. I returned my monitor to Acer but got it back unrepaired, they could not see the malfunction. But I kept on sending it back, until I got a new model. Now after 2 years I get the same thing with this monitor. But there's no warranty anymore, so I looked into the problem myself. I found out that inside the powercircuit board is connected to the mainboard through a 10pin connector. The 5 pins that are on the lowest row, show a trace of white powder, I suppose occidation. I sprayed a little of contactspray in it. I must say the problem is not gone, but much better. The problem shows not so frequent anymore and lasts not so long. At first the screen switched of for 3 to 5 minutes and came back on. Now the screen is gone for perhaps 1 second and returns. So I'm almost convinced the problem has something to do with the connection of the powercircuitboard inside and the mainboard inside, when the monitor heats up a bad connection occurs due to occidation of the 10 pin connector. If you find a solution that fixes the problem 100% let me know, please. Mario.

the problem must be with the step down transformer,it must not be adequate for the xbox power needs..an option would be to buy a proper transformer from play-asia.com at http://www.play-asia.com/paOS-13-71-er-49-en-70-1pnk.html (i buy my games there,they are good)
which city are u from?perhaps i can find out where u can get the power brick..regards
SOURCE: No power. Possible power supply issue.
If the repairman guarantees that the problem is the power supply and will agree not to charge you if that is not the problem, then by all means go for it. Most TVs it is what is called the Power supply Unit, or PSU, and the part alone costs well over $100...

sounds like your charging circuit isn't working or the adapter isn't putting out enough power or amprage to fully charge the battery, or you battery went bad. if the charging circuit is bad then so is *********** board, time to burry the system and buy a new one
