EMac Monitor Problem

Alright, I have an eMac G4, I think its 2nd or 3rd gen. Recently it has been having some trouble with its screen.
It boots up fine, but after no more than 20 minutes, the screen goes off. The light doesn't start pulsating and I can't turn it on again without turning off and on again, where I can have another 20 minutes TOPS. This only works for about three to five cycles before it has to sit without power for about a day before I can see anything. Booting in the normal OS (10.4.11) and its resore DVD(10.3.3) bolth have this problem. However, the Hardware Test extended test will find no problem, and the screen will stay on for hours if it is booted from the Hardware Test partition on the restore DVD. It has had this problem for a long time, but repairing permissions on the harddrive and removing/ replacing the backup battery seemed to work temporarily, until now.
When the screen goes off, I can still eject CDs, adjust volume, and it will play the error sound effect if I punch random keys.
I also have another eMac (first gen 700mhz) that works well except for its CD-RW drive. If I can't get the newer eMac working, I would like to salvage as much as possible and upgrade the older one. What all can be transfered? The whole logic board, RAM, HD, Superdrive? Any Combination? I am in need of a little more computing power, and been needing a new CD drive for years...
Thanks!

The best gadget for stubborn dust deposits is a pastry brush. Make sure you get one with a wodden handle and natural bristles to avoid static isses. I have close to a dozen in various sizes and shapes in my computer kit.
Be sure you know the exact version of the eMac you have before looking up take-down instructions. There are two variants: those with USB 1.1 logic boards and 700Mhz, 800Mhz, and 1Ghz processors; and those with a USB 2.0 logic board. The latter are mostl y1.25 and 1.42G processors but there are some uncataloged "edu-only" eMacs with the USB2 board but only a 1Ghz processor. That;s the version that leads be to this caution.
The case take-apart is slightly different between the original 4,4 eMacs and the later 6,4 versions. Some people have broken the power switch while trying to use the older instructions to take about a newer eMac.
The 4,4 and 6,4 codes come from System Profiler (Apple menu > About this Mac and then click the "More Info..." button). It the second line of the opening Profiler screen. A code of 4,4 on your computer means it's USB 1.1 and a code of 6,4 means it;s the later USB 2.0 version.

EMac monitor problem: bad caps or rastor shift or... ?

Something is wrong with my brother's eMac. About three years or so ago he had the bad caps (leaky capacitators) problem, and sent it off to Apple and got it repaired. But that wasn't the end of it. About a year ago the problem returned, though not in quite the same form. Originally, his eMac would freeze and get funny colours. This time if he has it set to anything higher than 256 colours the screen not only gets funny colours but appears to display twice (the top of the screen occurs again at the bottom, though it is hard to see in the pic). Here is pic:
The grey square in the middle is the cursor and it is selecting the monitor resolution/colors. The square surrounding it is the pull down menu which occurs again above it if you can make it out.
On 256 colurs, which is the only resolution he can work at, you get the following:
Here is a closer look:
It is only the small rectangles which are crazy colors - the rest is normal. Does this suggest that it is only one or two faulty caps, while the rest are fine? What else could this problem be?
Also, if we send it back to Apple, will they fix the problem again for free?

Looks more like the video ram is (has) failed to me you could try Apple again but don't think it will get repaired for free and probably not worth the cost as if it's a 1.25Ghz machine it's now around 7 years old and the CRT will probably go belly up soon as well - sorry.

Emac monitor goes black – slap brings it back to life

Last couple of days my emac monitor will just shut down and go black, just like an old TV tube packing up used to. It won't return on restart, but did return a couple of times after I took out mains lead from side of computer, let it rest, then tried again. However, today, this solution didn't work, but a tap to the side of the computer did get the screen going. I've read a number of different possible explanations for what might be the problem – everything from battery, to airport card to it's terminally ill, get a new computer, so don't really know what to do. Don't want to go and buy a new computer if all I really needed to do was change the battery. Any thoughts? Thanks in advance.

That's all good news. You have the later and better USB 2.0 eMac. However, the model is one containing groups of units affected by the logic board issues with bad capacitors. The logic board issues were most commonly associated with these serial number ranges:
G8412xxxxxx- G8520xxxxxx
YM412xxxxxx - YM520xxxxxx
VM440xxxxxx - VM516xxxxxx
[again, don't post your serial number here]
If yours is in the list, all you can do is keep an eye on it. Keeping it clean like you've done should help keep internal temps down and that may help longevity. The repair--if the shop can find an unaffected logic board---is nearly as much as a new Mac Mini.
If your board goes, and you are within driving distance of Salem OR USA, there is a shop that offers a low-cost repair of bad eMac logic boards rather than a replacement; it's much less expensive IF you don't have to ship a 50-pound computer round trip.
Your particular eMac can take advantage of newer, larger RAM modules that were not available when Apple engaved the specs in stone (Apple says 1GB max RAM). With the proper modules, you can increase RAM to a total of 2GB with two of these:
1GB PC2700 DDR 333MHz CAS 2.5 184 Pin DIMM
We have one of the above installed in my wife's USB 2.0 eMac alongside an original 256MB stick for a total of 1.25GB RAM and it's completely stable. However, you should get the RAM from the source I mentioned as they test in Macs. Similar RAM form a retail outlet may be PC-only.

Possibly mundane Mini-DVI to VGA into an external monitor problem

Hi,
I've had a look over the interwebs regarding my problem and it seems as if it's not unusual to have external monitor problems but I'm not sure if mine is slightly different:
I had a perfectly working set up with my new Macbook (the white one, '06 model I believe), that was connected to my Hanns-G HU196D monitor via a mini-DVI to VGA adapter, no problems whatsoever. But for a couple of weeks now my Macbook just flickers a light blue colour, with nothing at all on the monitor, and my macbook is unusable until I remove the adapter. I've read about updating firmware but I can't see my desktop once the macbook is connected to the monitor so it's not possible to configure anything. I've read somewhere that my external monitor isn't compatible with this set up, but it was until a couple of weeks ago!
My Macbook's 4 months old now and since then I've bought a new mini-dvi to vga adapter and a new VGA cable, no connections seem loose on either mini-dvi port or my monitor's vga port.
Thanks if you can help!
Jack

You will need to use a mini Dvi-dvi and a dvi-svideo/rca adapter.
Joy joy hallelujah.
Pardon the sarcasm...I just wasted 3 hours of my life trying to sort the issue out.
Heard a KWORLD PlusTV PCTOTV Converter SA235 USB 2.0 Interface would sort the issue out for under 40$ but it's not Mac.
Hope that helps.

Solution to clean the Emac monitor!

Does anyone know any solution to clean the emac monitor best beside the windex or iklear wiper?
thanks!

Vinh Pham,
Welcome to the Apple Discussions!
In general, don't use Windex; alchohol-based solvents can disolve the antiglare coating on CRT glass (whether an eMac or a flatscreen TV). Your profile shows 9.2.2 which says you have a first-generation nVidia graphics eMac; you can actually get away with using small (really small, as in barely moisten a cloth) amounts of Windex or the like, but it's not a good idea in general. You can actually get good rsults using nothing more than distilled water and a clean lint-free cloth. This was discussed recently in this forum; see JMVP, "CLEANING MY MONITOR" #1, 01:50pm Oct 22, 2005 CDT

M93p dual monitor problems; monitor turns off and cannot be turned on again

Hi,
we have multiple M93p tiny computers causing problems in dual monitor setup (VGA / Displayport->DVI). Our users (already >5) keep telling us, they leave their workplace, return, then DVI attached monitor if off and they do not find a way to turn it on. This is true; the only workaround that has been found by our users is to bring Win7/32bit into standby mode and awaking it again.
Needless to say, we turned all windows energy saving options off (computer standby/hibernate, monitor turn off). Still the problem appears.
Maybe there is something wrong with DVI power/DVI signal?
- Monitor independent, as far as I can see
- Independent from Windows energy saving modes
- BIOS updates did not help
[todo]: Try Intel/(AMD?) drivers, let users test.
I haven't seen exactly when the monitor turns off because it is reported by users. I had a testing machine, but was not able to reproduce.
http://forums.lenovo.com/t5/A-M-and-Edge-Series-ThinkCentre/Dual-monitors-problem-VGA-and-Displaypor... is related.
Anyone?
Thx

Make a "Genius" appointment at an Apple Store to have the machine tested.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

*An SSD doesn't need to be zeroed.

Activity Monitor problems increase CPU and power burn

Migration Assistant worked very nicely, transferring from a Powerbook G4 with 30GB of files and data in about 45min via Firewire.
However, after 2 days of usage, the CPU was still running at 80% and applications were incredibly sluggish. My battery calibration at full charge only showed a little over 1 hour. Activity Monitor also would not show any processes -- the list was completely blank.
The solution was to rename the Preferences folder, allowing programs to create a new Preferences folder. I then selectively populated the new folder with the main old preferences for mail, Safari, etc. This not only solved the Activity Monitor problem, but immediately drove down the CPU usage to about 10% where I'd expect it. Now the battery shows over 2.5 hrs on a full charge with the screen on full brightness (and it's BRIGHT!)
Also, Microsoft Word/Powerpoint/Excel/Entourage: trial software on the MacBookPro will mess up your migration, so delete the trial software BEFORE MIGRATION ASSISTANT.
Hope this helps some of you out there!

Another thing users who run Migration Assistant should know is that many of your background processes and helpers may slow down the Macbook.
For example, I notice that a bunch of PowerPC menu items running under Rosetta slowed things down. Also, the Microsoft Office Autoupdate background process, which is started from System Preferences > Accounts > Login Items constituted one Rosetta process running all of the time.
When I remove/disabled these background processes, I noticed a significant difference.

Screensaver eMac monitor while in extended desktop mode?

Officially, eMacs can mirror to an external display but cannot do extended desktop. Since my 2005 eMac's built-in monitor is only functioning correctly at low resolutions (see http://discussions.apple.com/thread.jspa?threadID=2013835), I'm using a program called Screen Spanning Doctor to run it in extended desktop mode. My eMac is running Mac OS 10.4.11.
*I'm searching for a way to run a screensaver and/or turn off the eMac's built-in monitor while I continue to use my external monitor.* Is that possible? I've configured my external monitor to function as the primary display while the eMac's built-in monitor is the extended display.
Thanks!

Hi all,
I've found a solution to my problem!
I'd forgotten that Mac OS X allows each monitor in an extended desktop configuration to have its own desktop picture. I copied all desktop pictures to a new folder, used the procedure described at http://www.macworld.com/article/51937/2006/07/savedesk.html to copy all Apple screensaver photos to that new folder, and then configured System Preferences => Desktop & Screen Saver => Desktop to use that new folder and change the picture every five seconds. EDIT: I selected "Random order" too.
This won't be too distracting since I'm using an external monitor as my primary display. Also, this solution should require only a tiny percentage of my computer's resources. Thanks again to all of you for your great ideas!

Emac Monitor Gone Very Blurry?

Hi,
The EMAC last night was fine when I got home from work, I read an email, then all of a sudden the display went blurry - like the effect on some slideshows, except it never recovered. Changing the resolution to 640 x 480 helps slightly but it's still basically not very readable. I unplugged the whole thing for 3 hours and when I turned it back on it was still as bad, if not worse.
Any ideas what this could be or what to do? I think it must be a hardware issue since we haven't changed any settings - all I did was look at an email!
Thanks in advance!
Lisa Jane

Lisa Jane etal,
I had the exact same problem in early March 06 and had steady blurriness for 8 days. My eMac 1.25 GHz is 2 years old and now running OS X 10.3.9 without any other troubles. I tried all the fixes listed in the posts at the time without success. While I was researching new LCD monitors on the web one morning, my wife came by and said, "That looks much better". I hadn't noticed, but the problem corrected during the session. I couldn't determine exactly when. I was preoccupied with my search. That morning, the only thing I did to the system was to update a photo editor program supplied by my camera company. It took a long time to optimize the HD after loading, but otherwise updated normally. Previously I installed Anacron v2.3 pl2, a program which initiates maintainence, that would normally be performed during the night by the MacX system, when the eMac is shut down. I usually leave my eMac in sleep mode. I installed Anacron to initiate the periodic maintainence during my random shutdowns. The monthly or weekly one may have corrected the blur for me, and I didn't notice it on the following startup. This is only a guess on my part. I really don't have the skills to assess such things.
I posted this good news, in case someone else still has hope that their blur problem can be corrected. I bough a new LCD 19" wide monitor anyway, and am enjoying the demonstration advantages this gives to two people viewing the screen data side by side. The Mac plug in adapters should also make it easy to use the new LCD monitor with 12 inch iBooks when my kids bring them by to show us their work and their many photos and slide shows.
Both monitors are still working great, but if trouble hits again, I won't have to ruin my eyes with blur for 8 days, trying to find the fix again.
The ScreenSpanningDoctor program reported in these discussions, and widely elsewhere, looks like a helpful addition to my two monitor new situation. I will try it for sure, if my eMac screen stays good, and I need wider viewing for future work with spreadsheets or photo editing.
Sorry I didn't report this good news earlier. My logon didn't work, and I hesitated to initiate a new account when the number of posts on this blur problem stopped for a while. Did anyone else have any success?

Emac monitor is very dull when I start the emac

Hi All,
For the past month or so, I have been facing this problem.
When ever i start the emac, the monitor is extremely dull and it takes a few minutes before the monitor regains it's original brightness and contrast.
I can't figure out what is wrong and how to resolve this problem.

2011 Macbook Pro External Monitor Problems

Hi all,
Looking through some of the threads, it appears that getting macbook pros to work with an external monitors is a big issue.
I've just bought a phillips 27" monitor and I'm having no luck whatsoever getting my MBP to see it. I've tried both HDMI and DVI using Apple's own mini adapters, but no matter I do, the monitor fails to detect any kind of signal and goes into sleep mode.
I occassionally get the blue screen flicker on my MBP as though it's trying to connect, but the monitor does nothing!!
I've tried most of the suggestions in other threads, which relate to earlier OSX versions, but nothing has helped.
I'm running 10.8.4 on a 2.2 GHz Intel Core i7.
If I fire up my Apple TV, I can use mirroring and the monitor displays my desktop no problem, but the picture quality is poor. So I guess the monitor works. I want to use a bigger screen as I use Logic Pro, so clarity is pretty essential when it comes to picture quality.
Any help would be most appreciated.
Best Regards
Phil

Hello Phil,
The following article provides a number of troubleshooting steps that I'd recommend looking into, especially testing with another display if possible, and resetting the MacBook Pro's parameter RAM and SMC.

New eMachine w/Windows 7 and HP f1703 monitor problem

Truly fed up at this moment, and not really tech savvy, but will try to be brief with problem:
Had an HP Pavilion a767c which came with f1703 monitor - purchased around 2005 or so ... ran great, no problems, monitor functioned beautifully. Had some storms come through area about 2 weeks ago, lost power several times, a767c started acting up (shutting itself off at night, but would come back on ... finally died, went through all the diagnostics, yesterday decided to purchase new controller, got an emachine at Best Buy, want to use HP monitor).
About a minute into boot, f1703 changes from a "starting Windows" message to a "PC video resolution setting out of range" moving message ... never comes up to Windows desktop screen. If I plug in an older CRT type monitor, everything comes up fine. Have checked Control Panel, shows emachine hooked up to generic monitor ... found resolution settings, they are set for the 1280 x 1024 and made sure was at 60 Hz. Just went through the diagnostic procedure here on HP for message during boot ... do not get any OSD when Menu button on monitor pressed ... I don't believe we've EVER pushed/accessed this feature in all the years we've had the monitor ... so I'm stuck at this point in going through diagnostics.
Any help greatly appreciated.

Dave, so sorry, but telling me my monitor is "VGA only" really isn't helping my confusion (original post did state I'm not too tech savvy). I had my stepson (who is more tech savvy) work with the link you provided previously to download updated driver info from Intel. Here is a rundown of everything we worked on yesterday with this beast:
As a recap - if I hook up the f1703 directly to the emachine (video port states HDMI on back panel) and boot the machine, get the normal starting boot display and also a "Windows starting" display ... before the desktop screen comes up, the monitor goes into an error message stating resolution not set correctly at 1280 x 1024 @ 60Hz. From that point, I never get to the desktop, the monitor is basically frozen. emachine is running Windows 7 64bit.
Pressing F8 during boot will allow me to get into Safe Mode, but in Safe Mode I can't download anything, and I'm very limited in what I can/cannot change.
If I hook up an old CRT style monitor FIRST and boot the emachine, everything comes up normally ... I was able to find the HP f17093 driver in Windows 7 and get that driver set up with the 1280 x 1024 @ 60Hz resolution. AT THAT POINT, if I unplug the CRT and plug in the f1703, I can use the computer normally and the display is excellent ... so to my way of thinking, there has to be an issue with some video command during boot that is sending a false signal to the monitor. Make sense???
I hooked the f1703 up to a different emachine (also running Windows 7) and I have the exact same problem ... locks up during boot before desktop screen. For the heck of it, I'm going to try hooking the monitor up to a Sony Vaio laptop running Vista later tonight to see what, if anything, I get with that.
Downloading the updated driver info from Intel really didn't accomplish anything positive ... although the Intel site stated there was updated drivers available, after downloading the emachine had picked up some kind of generic flatscreen driver to use and same issue existed, so that's not what's doing it.
Oh, one other thing: after getting the complete boot on the CRT, then switching plugs to hook up the f1703 I was able to access the monitor's OSD menus ... went through and reset to factory settings ... no difference ... monitor still hangs during boot when hooked up first directly.
Dave, when you said VGA only, are you trying to tell me the output on the video card is not correct for the f1703 monitor? Sorry, I just don't understand the HDMI stuff (what that is in layman's/idiot's terms). Do I have to have a different video card? Adapter?
Thank you both (CherylG and Dave) for your patience and assistance ... this is just so frustrating. I used to understand alot more back in the DOS/CPM days.

Mac Mini DVI Monitor Problems

Hi all,
I'm running OSX10.8.5 on a Mac Mini 2.5 GHz Intel Core i5 with 4 GB 1600 MHz DDR3 memory and Intel HD 4000 512MB graphics.
I've just upgraded my monitor from a VGA 17" to an AOC E2462VWH 24" monitor, plugged into my computer via DVI with a Thunderbolt adaptor.
In a normal boot-up, the monitor displays video for a split second and then cuts to black. The picture works fine in Safe Boot mode but video is jerky, everything loads slower, I can't play .mov files (Quicktime tells me unknown error -101) and there is an annoying flicker every 10 seconds. The fact the monitor works fine in Safe Boot suggests to me the problem is software. Resolution is set to 1920 x 1080 @ 60Hz and OSX is not letting me change that via Settings.
I went searching for drivers only to lean it sounds like OSX deals with monitors in a plug-n-play format. Is this true?
Firstly, can I confirm my mini has the power to drive this monitor?
Besides that, can you please help me figure out how to boot this computer so the monitor displays in normal boot-up mode?
Thanks for your help!

Then it sounds like yo need one of these:

Dual Monitor problem and an idea

Hey everyone. I use two monitors and when i have iTunes open on the primary one(the laptob monitor) i am able to scroll through my music in iTunes using my mouse wheel. However, when iTunes is opened on the other monitor, scrolling through songs with the mouse wheel doesnt work and i have to do it using the scroll bar. Other applications such as firefox scroll just fine on both monitors. Any ideas??
Also, I couldnt find anywhere to post suggestions so im just gonna do it here. I think it would be nice to be able to save playlists and then be able to load them if you ever have to reinstall itunes or there is some other issue. I know you can just put the music into categorized folders in windows explorer, but that doesnt allow you to have the same song in more than one playlist unless you copy the music file. I dont think it would be very hard to do, just save to some file that stores the file name and location of each song. then upon importing the playlist, it could scan the saved location for that file and add it to the playlist if its there, and if not it could ask you what other folder it should scan in for that song. I think this would be very beneficial for people that create many large playlists that would take hours to recreate.
Thanks for your help,
Adam

I assume you have installed the latest drivers for the card? I have that
card and dual monitors with no problems. By the way, go to the NVIDA
site and download the drivers, not the Sony site as some do. There was a
new version of the driver just last month.

Bootcamp, Windows 7, External Monitor Problem

I am trying to hook my mac up to my 32" JVC monitor. It works perfect on the mac side, but when I turn it over to the windows 7 side there is an issue. If I do 'duplicate these displays', half of the bottom bar is cut off and about half an inch or so of space is cut from all edges. This is not an issue all the time, but it is annoying and it does get in the way on certain occasions. How would I fix this? I have tried the different resolutions, but to no avail, a lot of the space is still cut off. I have tried 'detect' and 'identify', but neither of those work. I've tried going into the nvidia panel, but there is no option to adjust the resolution manually to fit the screen.
The problem isn't so much the resolution. The resolution is perfect and crystal clear! The real problem is that so much gets cut off the edges. Is there any way to manually adjust it to where it needs to be?

Okay, well, I got it to work, but only in single mode (had to disable the actual mac screen).
Is there a way to do this in duplicate/mirrored mode? I know on the mac side everything fits perfectly even in mirrored and everything.
