Question about Apple eMac G4 Desktop

EMac sound will randomly go to FULL BLAST

Sound will go to FULL BLAST for no apparent reason - sometimes happens when running a net application (YouTube, for example) that uses sound.   Sometimes fixed (temporarily) by a restart - have tried zapping PRAM (also a temporary fix).  Sound will show as MUTED in System Preferences but still be at FULL BLAST coming out of speakers.  Any recommendations?

    Not sure what a "brand driver" is.  Pls clarify what it is, and how I can check whether I have one.  This machine had been working just fine for years, and this problem started occurring in the last couple of months.

    and THANK YOU arnomonfort for taking the time to respond - if you can clarify, I would be very grateful.

    Norwoom01:  Don't think so - but this is a family computer used by others, so it's possible.  Any suspects?

    Did this and it worked, but didn't want to rely on external speakers forever (and I had to keep external speaker volume set very, very low).   Ended up having a local technician replace the logic board, which appears to have done the trick.

    Did you install/update anything a day or two before the problem first occurred?

    don't you have a brand driver working over system preferences?

If you don't get it fixed, try hooking up external speakers. The external speakers have a hardware switch that prevents it completely from going to the built-in speakers.

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.

The Safari browser on my EMaC is apparently

The first thing I'd try would be to delete its .plist settings file.

1. Click on Finder (the smiley Mac guy).
2. Click the "Go" menu at the top of the screen.
3. Click "Home". This will open a window showing your Home folder.
4. Double-click the "Library" folder.
5. Double-click the "Preferences" folder.
6 Look for the file called-> and drag it to the trash (or click once on it and press Command-delete).
7. Now run Safari and see if it works.

You can also probably (depending on the version of Safari):
1. Reset Safari from the Safari menu at the top of the screen *when you're running Safari*.'

If your operating system is Mac OS X 10.3 or earlier, upgrading to 10.4 will (in addition to lots of improvements) allow you to use a newer version of Safari.

Good luck and please let us know how well this works. Please rate me if this solved your problem. If not, please repost and we'll give further help.

Emac won't start up

An Emac! one of my favorite CRT Macs :D

They sometimes had a problem of the vibrations of the speakers killing the CRT Tube. But it sounds like you are having worse problems.

the first suspect would be bad ram. Try removing one stick, then the other and running it with only one stick. If you only have one stick, then get ahold of a new stick and try that. There is a little rectangular cover on the bottom of the computer that your ram hides under.

If that doesnt fix it, return any purchase of sticks or ram and lament the death of your mac. Not that it is not fixable, its just cheaper to get a new one, and hey, unless your hard drive is fried, you can even get all your data off! How cool is that?

DISCLAIMER: You are dealing with a CRT (Cathode Ray Tube) Monitor. It can and will shock you if you touch the wrong bit. Possibly even lethally. EVEN if it is unplugged. If you dont feel comfortable opening the case, pay a professional.

Here is a link showing how to take apart your mac.
This also has a good picture of the memory cover.

Once you have the hard drive out you can get and IDE to USB cable or hard drive enclosure, and hook your old drive up to your new mac, and use the migration utility (in the utilities folder) and pull your whole account (applications and all) to the new mac.

You can get a 1.4GHz Emac for around $200 these days.

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.

Skype refuses to quit, No applications open - error 18010

Try forcing the computer off by pressing and holding the power button until it shuts down. And then on boot press and hold command+option+p+r until you hear the power up sound three times. then it should be better hopefully

EMac freezes quickly and regularly after startup

This model has problems with the capacitor buldging and or exploading, check under the unti where the ram goes open up that capartment if you see any capcitors exploaded or buldging then its is going to need a new logic board, Since these units are out of warranty your best bet is to scrap it.. Mac had this problem and they agreed to fix it but its been more then 4 years so if you do not have extended warranty on it your out of luck.

Slow running mac

There are a number of reasons that may causing a Mac computer running slow, but generally two factors: hardware part & system part. For hardware part: I guess it's OK if your Mac is not that old. For system part: there might be a lot of junk files, caches, registry errors... about 80% slow Mac caused by this reason, if so, try cleaning the system. Learn more the solution here:

My eMac seems to get slower and slower all the time. Using version 10.3.9 and whenever I switch between applications it spins.

You will need to check for BAd caps on this look under the memory lid and see if the caps are bulging if they are you got a emac that is failing and you would need to send it in for repair you can take your logic board out as i did look at my pics look at the caps the round thigs there bulging this means they need to be replaced so I am going to try it myself but you can take it to this guy will do it for under the price it would cost for a new logic board.

Imac a1002 turns on sometimes moniter works or sound only

The eMacs had a problem with the logic boards where they would turn on and not display video, you can check to see if yours is affected by removing the RAM door and looking at the capacitor to see if it is expanded, it most likely is. The unit unfortunately is not worth getting repaired.
