PowerMac G4 Cube not powering up

[HighSpeedDirt]

Bought a new power supply thinking that was the problem still nothing and changed the internal battery and nothing. Dont want to send to apple due to finances being tight. Usually fix things myself so if anyone has some ideas on what i should look for i would be greatly appreciated.

It could be the DC to DC converter card is bad or has just come loose.

To check and see if it is loose

When you plug the AC adapter into the wall and then into the Cube, do you see any LED lights turn on inside the cube itself, specifically on the motherboard (its either red or green, I forget exactly atm)? That can tell us if its getting power or not.

well its been awhile since i posted that and i have changed the dc board but still nothing. Already sold the powersupply i bought before so i guess it is Mother board. No lights at all when i plug in but when i did go to plug in to the wall after hooking dc board up it sparked when plugging to wall but didnt do it anymore. Would like to know if i should just take hard drive and ebay the rest or can it be an easy fix?? More help would be appreciated

I would highly reccomend posting your problem HERE for some input from what may be the last group of dedicated Cube owners/users. I haven't done enough with mine to really be of much help, but there might be someone over there who knows if you don't get an answer here.
