Mac G4 wont turn on.

Not sure what else to put, i have checked all the power sources, Does anybody else think it is the power supply in the system.

Thanks in advance.

If it's completely dead (no clicking, whirring or any other noises when you attach power cord and no sounds when you press the power button) it's a good bet it's either the power supply or the power cord. (If there's a break in the power cord, no power can get to the system.) If the system is still under warranty, the power supply is covered.
You may need to replace the battery on the motherboard:

If the fans and LED turn on, you may have a more serious problem:

The battery was replaced and the problem still persists. No lights anywhere, no sound.

Almost certainly power supply. I think you'll need to get a Macintosh one but a) they should be very easy to get hold of second-hand, reconditioned or salvaged b) they are cheap and c) you can install it yourself.

San Diego, i did check the stores, but they dont know what wattage, when i ask for g4.

Yeah they're talking about standard PSU units for PCs - they simply won't work in your G4. You need to get a proper Macintosh one. A G3 PSU will work (I've fitted one successfully before) but it needs to be Macintosh. Ask at your nearest Apple dealer (if there is such a thing) if they have any spares they could sell you cheaply. Don't pay more than $30 at the most. Maybe even check ebay for a G4 PSU?
