Macbook screen won't work, but external monitor works fine...

Hey guys - are there any solutions out there for this problem that doesn't involve hundreds of dollars? A mate of mine spilled beer on a macbook - had to pay for it, I fired it up and everything works fine but the screen... Is there a way that I can check the connections or dry something off? Apple told the owner to throw it in the bin - but it works fine plugged into a monitor. The screen isn't cracked or chipped - all looks fine - I'm guessing that fluid had got into a connection somewhere. Help me Gurus!
Cheers

Have you tried drying it without the back cover and upside down? l heard it worked for some guy

Monitor has weird, pixelated colors, but external monitor looks fine

I have a MacBook Pro. It is a couple of years old. Recently the monitor started fritzing out. At first it would happen only happen when I ran windows through boot camp. A couple of days later, it began happening in os x too.The screen seems to be operating on a reduced amount of colors, a preponderance of green and everything is pixelated. There are blobby shaped circles of rainbow all over the desktop. Windows on top of the desktop look better, but still way too green and pixelated. All parts of the screen are equally bad. I tried changing all the settings in display. Also ran disc utility. The display on the external monitor looks fine. Any ideas on how I can fix this?

Some MBP have bad nVidea graphics chips that can do wheat you describe, except it usually affects an external monitor as well. It's covered by a warranty extension program here:

Satellite M30X-111 screen doesn't display anything but external monitor works

My laptop screen just doesn't display anything (look like when the computer is off) but when I connect the external monitor, then the desktop will be displayed on that monitor. I tried to recover the laptop using the recovery disk and it worked again, but today, it stopped working again.
I again have to plug in the external monitor, and after I tried to reboot, I keep pressing F8 but the start up mode doesn't come up, only the sound of when you keep pressing a button for too long beeps, however, the laptop monitor works again.
How do I fix this problem?

Hi
According to your first posting I presume that LCD display on your notebook is defective. If you can not see BIOS settings or Toshiba welcome screen there must be some display problem.
Experiment with external display is to be sure that graphic card is not responsible for that. In your case it works with external display and graphic card can not be responsible.
Like I said try to enter bios settings and report if you can see Toshiba welcome screen.

After Logic Board replacement Built in Display not working but External Monitor is

Had to replace logic board in my Mid 2009 17' MBP as it wasn't powering up at all.
Since putting in refurbished logic board MBP powers up and actually works perfectly with an external monitor but built in display is dead.
In 'About My Mac' initially it showed Color LCD as being connected., but now it doent.
Can anyone tell me if this is a problem of the refurbushed logic bioard from this ionfo - or if there is a w ay of being 100% sure that it is the logic board and not the display.

Shine a bright light at the screen and see if the picture is there, but the backlight is not there.
Working inside MacBook is very fussy work, and it is far too easy to make connections that seem fine, but do not quite work, or to disturb earlier work during re-assembly. Just to vex you even more, the screen connections go through the hinge area, and are subject to constant movement and stress.
I tend to first blame the last thing you changed (working inside your Mac in this case) as the source of the problem over random failure, until I can use classic techniques (such as substituting know-good parts) to rule random failures in or out.
If you did not follow proper grounding and static-elimination techniques, you can cause major damage inside. Tiny shocks can ruin electronics long before you feel the spark.

MacBook Pro won't sleep with external monitor

Hello,
have a problem. I'm using external monitor with my MacBook Pro. If I close the lid, I see all windows on external monitor and Yosemite won't sleep. Can you help me please? My external monitor is Samsung 21.5" and I'm connecting it to MacBook Pro via DVI.
Thank you

Hey Renecek,
My first thought was, "Hey, you are using closed-clamshell mode".

But then I realized, wait, you want it to sleep.
For that, check out the suggestions in these articles.

My macbook pro will not detect any external monitors

My macbook pro will not detect any external monitors, worked 'once' when connect to a TV.
Have read a lot of web comments, most not very usefull.

Hi a,
Check the setting in Sys Prefs > Displays.
Try a different adapter and/or cable.

I have a PowerBook G4 with a non-functioning monitor. It used to work with an external monitor, but I reinstalled the OS, which cleared the display preferences and now when I restart it won't detect the external monitor. How do I fix?

I have a PowerBook G4 with a non-functioning monitor. It used to work with an external monitor, but I reinstalled the OS, which cleared the display preferences and now when I restart it won't detect the external monitor. This means I can't use the computer anymore. How do I fix? I tried using the Command+F2 keyboard shortcut, but it doesnt' work. It's possible that since I reinstalled the OS, it still needs to be set up, so there's only a welcome screen (but since I can't see it I'm not sure).

There is no limit to the number of times you can re-install Office on the same computer.
You can activate by telephone:

My external monitor works but I can't get my screen to work on my power book anymore

Can not get my screen on power book G4 to work but my external monitor works fine. Did I press something and turn it off?

The both screens always worked fine but now the power book doesn't show anything on the screen. I didn't drop it or even move it. Where is the brightness button? Could I have hit it by mistake?
Thanks so much for your help.
F2 is the up-brightness button, F1 is the down-brightness button, usually, on PowerBooks. If for some reason the F1 button got held down for a couple of seconds, the display would go completely dark.
That being said, if the backlight does not come up (easily determined by seeing if the Apple outline on the cover is lit up) then the most likely suspect would be the inverter board, or the connection to the inverter board. If this is a Titanium PG G4, the inverter board is easy and relatively inexpensive to replace. For the Aluminum models, I don't know if that is quite so true.

My mac won't recognize an external monitor. The screen Goes Blue Once, then goes blue again and the second monitor just turns off. I am using an HDMI adapter to a visio TV. I also have my xbox on the tv. Can anyone Help??

Lol, figured out the first part. Just for those who may be searching, when you click on the Display Preferences, and click on the arraingment tab... it not only shows where your two screens will be displayed, but the WHITE BAR at the top of one screen is the dock/toolbar. Click and hold to grab this and just slide it over to the screen you'd like it to be on.
You have to release it IN the screen box, not on top of it... and it should pop right over to the new (or old) screen. At any rate, you can put the dock on either (or any) screen that you prefer.
I am thinking of ordering more of these. Lol. 3 monitor setup seems like it would be crazy good.
Still looking for the answer to keeping the new 16" screen on the right without switching between screen #s with that... not expose... Lion feature.
Thanks. Hope my other question has an answer out here.

I downloaded a web site isytd video downloader on my macbook pro, to download videos. but it didnt work , so I removed the softwear from my mac, even I removed it the download sign appears on the left top of my video screen, so I want to remove this

I downloaded a web site isytd video downloader on my macbook pro, to download videos. but it didnt work , so I removed the softwear from my mac, even I removed it the download sign appears on the left top of my video screen, so I want to remove this download sign. How can I get this done? Please help me.

Many apps are not completely removed if the .app file is trashed (which is what I believe you've done so far).
If you don't want to dig through the system to manually remove library files, I recommend the use of AppCleaner, which does the job for you.

New iMac won't recognize my external monitor.

I just upgraded my workplace computer to a late-2012 iMac (with the thin edges) from the previous older model.
I have an external monitor that I use as a secondary screen - a Samsung SyncMaster BX2440 - that worked great on my older machine using the DVI adapter.
When I plug the same adapter into my newer machine, it won't recongize the external monitor.
I tried resetting the PRAM, but no dice.
Is this a Thunderbolt issue, and if so, how easy is it to resolve? Do I just need to get a newer DVI adapter?

Loner: I looked at that and it only shows the main iMac display. Doesn't show the other device.
The model I'm using is a Thunderbolt machine (has the lightning bolt arrow icon). The previous machine was a DisplayPort model.
The adapter is the Apple-issued DVI adapter, but I'm guessing that even though TB and DP use the same physical plug interface, the adapters are not compatible?
(The adapter has the standard monitor icons on it - box with vertical lines on either side).

Mac powerbook g4 15" Auminum, on startup has a black screen and no signal to external monitor

Powerbook G4 1.5 Ghz 15" Aluminum
After watching a dvd, I turned the laptop off and closed the lid before the screen was completely dark. I also forgot to take the dvd out. The next day I get a start up chime and a black screen. Will not work with external monitor. Will not let me do pram reset as I couldn't see the picture anyway. Hard drive appears to be fine. I tried swapping the two ram modules. Took the lower one out and still no results. My main question is, before I just geek out and put a new logic board in, what are the possible loose connection (cables) causes?

This issue is not unfamiliar among PowerPC G4 users, in desktop or portable models.
The cause may vary and so when looking through incidents of a similar nature, try to
be patient and get past duplicate-sounding experiences as referenced by the sources.
There are more than a few in this search thread that sound like your situation:
https://www.google.com/?gws_rd=ssl#q=powerbook+g4+black+screen+on+startup
Depending on the PowerBook model, some have clock battery/capacitor on logic board
that once it fails, there can be startup issues as a result... So that's one to check. And
then there are the connections that may have come loose on the logic board, over years
of handling and small movement, these could finally have failed to contact finally. Or the
DC-in Board may have chosen to fail, so power may be unable to get past a circuit.
Troubleshooting based on a few symptoms can be... troublesome, tedious; or costly.
The iFixit.com guides have sections where people asked questions, such as:
https://www.ifixit.com/Answers/View/131619/PowerBook+g4+has+startup+chime+no+ima ge
The keyboard shortcuts to attempt to force a computer to start may be of no avail if
the hardware has defects, or if wires have come off their necessary junctions inside.
If you have time and some money, companies who specialize in repairing Apple
portable computers could restore its function & warranty their work. wegenermedia
is worth contacting if the computer is one you want to keep around while. They did
a repair for me on one of my Apple portables, and I'd probably go that route again.
So, anyway, if the unit uses a clock or PRAM battery, it may need replacement.
Or in another direction, issue could be a power related circuit failure; or worse.
There are graphic display components that fail at a point where an external &
internal display both won't light up. These are mapped out in iFixit guides or in
others online, depending on the model G4 PowerBook they show.
Good luck & happy computing!

Macbook Pro won't boot with external HDD plugged

I have a weird problem. My late 2008 Macbook Pro won't start with external HDD plugged either FW or USB... The screen stays white until I unplug it and then the Apple logo is there.
Anyone know any solution for this? Or anyone have the same problem

yeah I had the exact same issue with one of my 750GB externals too. I just left it for a while (about an hour or so) and it was fine..
I believe its so slow because the system is indexing the drive, which can be a very slow process if the drive is big, has a complex folder-hierarchy, and/or is fragmented.
Does the hard-drive appear quite quickly in Finder once OS X has started up? if its slow it may confirm what I've just said.

Have you tried resetting the PRAM? shutdown the machine, hit the power button then hold down the option and command keys with your left hand, while holding them down with your right hand use your pinky to hold the 'P' key and index finger to hold down the 'R' key. hold them down until you hear the 'bong' sound twice then release the keys and let the machine bootup.
Also try resetting the SMC. Shut the machine down. Hold down the 'shiftctrloption' keys with your left hand, right hand hold down the power button for 10 seconds then release all. Power up the machine as normal.
Hope this helps. Pls update us and let us know if that helps!
