Q: iMac g4 1.25mhz monitor problem

I have an iMac G4 1.25mhz. The power supply died. I replaced it, and the boot tone plays, but the monitor is black. No power light on monitor either. Help!

iMac, iOS 5.1.1

    I turned it on tonight, in a dark room.  The screen dim, but visible on the left, and almost black on right. What to do.

    I believe so, but I would like to get the built in monitor working.

    I have been reading and researching, and I noticed that the solution to iMac G4 monitor dark problem is too often to plug in an external monitor. Most of us iMac owners can afford a "better" computer, but would rather have the ORIGINAL iMac 100% working. Display and all.

    My problem is (I believe) the inverter assembly, or the video cable. From what I've read, the inverter could just go out, or in the re-assembly process the video cable could very possibly get pinched or otherwise damaged. The video cable is VERY delicate.

    I don't know how to tell which is the problem.

    I am having the same problem with my g4.  When I went to a repair place to ask about it they said its time to get a new one.  I do not like that option. So I would really like to know how to fix it. Mine was working one night I put it to sleep and I thought it would not wake up in the morning. Not the case.  I am going to have to see what it looks like in a dark room.
