    I believe this info from wikipedia let's us know that this is commonplace. To quote it:

    To Apple's detriment, a number of eMac machines have suffered from what
    was known as "Raster Shift", a strange phenomenon where the bottom
    third or half of the screen goes black, with the rest of image shifting
    upward and out of the top boundary of the display. Serious static also
    accompanies the problem, rendering the viewable part of the screen
    virtually useless. In response to the problem, Apple offered a solution
    which involved the replacement of a video cable inside the eMac's case.

    Here's some links on regarding this.

    There could be a couple of things wrong with the unit, first I would try a software update, that will take care of any software issues with the unit, second the unit may think there is an external monitor connected to it, check the displays system preference and see if a second monitor shows up, if so turn off the mirroring aspect and the screen should go back to normal

My Apple eMac G4 M9425LL/A Desktop does not fill up the desktop. How can I maximize the desktop

Hi Buchi
Do you mean you get a small desktop inside the screen surround by blank space or black?

If so then I think you are reaching the end of the eMac's life.
These machines have been very good overall. Some had the dreaded capacitor problem , but Apple fixed that on affected machines by replacing the motherboard.
I have of late though seen a few eMacs with display problems. I have one here now with a very pink display - as a computer it works fine, but the display (or display electronics) is giving up.
Unfortunately it is probably not cost-effective to try to repair these machines.
One thing you can do though is connect up an external monitor.
See if you can borrow one and plug it into the video out port (the socket right at the end of the line of connectors on the side of the eMac) You'll need a suitable adaptor though.
`If that display is fine then the problem is with the tube itself, but if the problem is still there, then then the issue is probably the video board - again not worth repairing.

let us know what happens.

Maximie desktop to full screen

right click on the blank screen, click properties, then settings and increase the resolution and color. If that doesn't work you might be using an lcd screen with the wrong settings. I don't know what that might be but you might call up support, for your brand, and tell them your problems. (you could also google manufacturer name then goto their site and email their support)

Black emac screen

Hi, this could be a number of things but the most likely cause is probably the leaking capaitor syndrome.At about the time these machines were made there was a flood of faulty capacitors throughout the electronics world and the factpriews that made the mother boards for the eMac were particularly badly hit.Did the screen exhibit any flashing or streaking or random freezing before the failure? Thses are typical precursors.
Unfortunately the only thing you can do is to take it to a (Apple) repair centre where they will be able to judge if it is repairable or not.The leaking capacitors quite often ruined the mother-board. If theyu were caught in time they were repairable but .......
If the eMac is still running, connect it to an external monitor and then clone your HD to a blank HD using Carbon Copy Cloner or SuperDuper.

I have an emac G$ 700Mhz 128MB/40GB/Combo with two related problems: 1. On power up, I get a blank grey screen that, after a while, changes to a similar screen, except that at its center is a small...

I've never used a hair pin-- a straightened paperclip has always worked for me.
One alternate solution (if you have another computer available) would be to boot the eMac into target disk mode by holding T during startup. It should show a firewire icon on the screen, and should act like an external hard drive when you connect it to another computer via a firewire cable. You can use this method to install the OS onto the eMac from another Mac. You can try Googling "Target Disk Mode" if you need more information.

Where is the mac desktop power button

It is a flat screen computer, and unlike PCs that I am used to, there is no "tower" that goes with the monitor, which is where the power button is. My sister-in-law turned the flat monitor around and found the power button (which is also flat and not that easy to feel if the screen is facing you) in the lower left quadrant (almost to the edge).

Screen stays black when i turn on mac g4 desktop

Have you had any screen problems leading up to this? Things like random freezing while moving the pointer or dragging a window, or disturbances to the display like tearing or jaggy edges appearing randomly?
If so then you probably have a faulty motherboard caused by the infamous leaky capacitor problem. This was a world-wide problem but it appeared to hit the eMac particularly badly. You can check it by opening the little panel on the bottom of the eMac (small cross-point screwdriver and 1 screw) and have a look at the capacitors inside. You can see 3 or 4, they are silver cylinders. If they show signs of bulging or any gloop oozing from them then that is the problem. It is repairable but Apple will probably tell you to take it to a repair centre as they don't carry the spares anymore.
Best option is to try a TV repair man as the skills needed are more TV repairman than computer tech related. However - big problem is that given the age of the eMac, there is a good chance that the gloop will have caused corrosion on the motherboard - and that is NOT repairable.
Be prepared that you may have to buy a new Mac. Your data is safe on the HD as that will not be affected - get the TV man to take the drive out for you - the high voltages inside can kill - (better kill him than yourself) and then install it in an external case to run on your new Mac Without being with the machine it's difficult to determine any other problem that it could be.

Monitor won't "sync"

Analysis procedure on this one is straightforward, though equipment intensive.
1) Put a different display on the Mac and see if it works better.
2) Put a different computer on the display and see if it works better.
Until you do this, we don't even know what component is at fault. Once we do, you can proceed from there.

EMac stuck on loading screen

Well i don't know of a fix for the issue u have, but i do have a tip and you might be able to fix the issue you have this way as well. But if you plan on transfering files from one mac to another esp. if one is either an older mac or a portable. you would always want to make one or the other a target disk instead of two stand alone mac's.
Why, because your eMac's older and the data transfer might be failing or can't process the data fast enough to get broken down to bits to be put back on the other end thru the cat5 line. But to transfer files of over 1 GB i would recommend you start the iBook in target disk mode. But since your eMac is the one with some issues put the eMac as the target.
To connect two mac using TDM (Target Disk Mode) you will need to get either a 6-pin IEEE to 6-pin IEEE firewire 800 cable, a 6-pin IEEE to 9-pin IEEE firewire 800 cable, or a 9-pin IEEE to 9-pin IEEE (if your eMac has a 9-pin port) firewire 800 cable.
Then you connect the cable to one of the eMac's 6 or 9 pin ports and the other end to one of the iBooks firewire 800 ports. (the iBook has both the 6 pin a48d559.gif and the 9 pin. 24a3000.gif800 ports) To start up as the target disk you press and hold T immediately after pressing the power on button. once you see the firewire symbol bounce around the screen you can let go. Now its like connecting to a external hard drive.

Network a G4 (OS 9) to a eMac (OS X)

OK - first, crossover cables let you network PCs together without a switch or router. I would strongly recommend returning the crossover cable and buying a router so that you can use both computers on the internet at the same time.

Second, the eMac monitor can not directly be used as a monitor for your G4 - it's not built that way. However, you can use Screen Sharing on OS X (if both have Leopard) or Apple Remote Desktop software (if you buy it) to remote control the G4 using the eMac.

You will DEFINITELY need a monitor on the G4 in order to set it up at all, so I hope you have that.

Keep in mind that you can buy, for less than $200, an LCD screen that is larger and better quality than the eMac, and it would leave the eMac useful as a second computer. Since the eMac is unlikely to work at all with Leopard, and you'd have to buy Apple Remote Desktop, you're going to spend less money by buying a separate screen for the G4.
