Macbook pro: blank screen on start up? help!

my macbook pro had a blank screen on start up. I tried restarting it and nothing worked. I could hear the computer running, but nothing would show up on the screen. When I would shine a light at the screen on start up I could faintly see the apple, but after startup it would go completely black. Then, off a whim, I tried plugging it in to our tv via an HDMI cord and it shows up now on the TV but still nothing on the computer display. How do I fix this?

Can you try Command+S for Safe Mode boot? OS X Mavericks: Start up in safe mode
What year/model is your MBP?

Pavilion p7-110c blank screen on start-up

My Pavilion. P7-1107c has a blank screen on start-up. There is a white flashing underscore mark in the upper left corner. I have tried the f-10 keystroke recommendation with no success. Lights and fans are operating, and the cable is securely connected. There is a one-second display on the monitor of the hp logo (the hand with the building blocks) a few seconds after start-up, which immediately disappears.

Hi,
Your PC is listed as coming with Windows 7 64bit - if this is correct, try the following.
If you don't already have one, use another PC to create a Windows 7 Rescue CD. Download the ISO from the link below.
Windows 7 64bit
You should use an application such as ImgBurn to burn the ISO to a CD - a guide on using ImgBurn to write an ISO to a disc is Here. Once created, or if you already have this, insert the CD into the PC and restart to boot from it. Select the Repair option.
Select the 'Repair your Computer' option and follow Option 2 in the guide on the link below to run Start-up Repair – you may need to run this 2 or 3 times.

Blank Screen after start-up chime, won't start

I'm rather perplexed as to what's happened to my PowerBook. I'll run throught it
PowerBook 12" 1.33 768
Background:
I've just updated it to 10.4.4, which caused it to get stuck at the Apple symbol and spinning wheel. I had to restart in single user mode and run applejack, restart again and it was fine.
Recently the PowerBook started to not wake from sleep, I'd have hold down the power button then restart it. I thought it had done teh same thing today, but this time it makes the start-up chime but gets no further than a blank (dark, black) screen.
I tried inserting the Mac OS X CD and start up holding down the C key, but still same blank screen (with the added benefit that I'm now unable to remove the CD)
I tried plugging it into an external monitor, but nothing.
I've tried resetting the Preference RAM and the PMU. With some limited success. On occasion after resetting the PRAM, turning it off then back on, it starts with something like a extra blow of air from the fan and white blank screen instead of a black one. It then won't turn off at all, the only way is to pull the power and the battery.
I've noticed that when the ac adapter is plugged in and i've the white screen it flashes very quickly, orange.
I tried starting in Tartget disc mode connected to an iMac, the disc doesn't appear.
I tried starting up with an external firewire drive attached, nothing.
I've tried starting holding the keys for open firmware mode, nothing.
I've removed the AirPort card, no change.
I removed the extra 512mb RAM with no change.
The screen is clearly working, has anyone any ideas how to get it started?
Any help would be appreciated, it's a second hand PowerBook and so has no AppleCare.
Cheers
Stuart

I had the EXACT same problem happen to me, Stuartea71. My PowerBook crashed on the on Feb. 4th and I still can't figure it out. I had just dowloaded the 10.4.4 update, bought iLife 06, and ordered a new battery.
I tried every single thing that you did above. I finally called customer support, and walked me through a few things which I had already tried, but she finally pin pointed something in disk utility that I missed. My disk would not mount. In red letters it said "failing." She told me that was a internal HD problem that needs to be fixed by a certified tech.
I did something I'd never done before. I put my HD to sleep to optimize battery performance. I work with podcasts and downloaded a large file. Unfortunately I forgot my battery setting. I chalk it up as a lesson learned, and just bit the bullet and ordered a MacBook Pro.
BTW... if you all customer service they basically read directly from the Apple Website. I paid $49 dollars for someone to tell me my mac was broken and send it in.

How to avoid blank screen when starting?

When starting my mac book air, it only shows a blank screen, any suggestions to get back to normal?

Hi Daniel,
By blank do you mean that the screen is black? Is it gray? Is it blue? The word "blank" is vague when trying to determine and isolate startup issues.

IMac blank screen at start up, just fan whirl.

Well I've got myself a bit of a problem, my computer is usually left on all the time with the odd restart here and there, anyway it got turned off today while I was out of the house and now it's stopped working.
Simply put, after the startup chime there is nothing but a blank screen, no lights on the keyboard or monitor, none of the start up key combinations will do anything so I can't even open the disk tray to try a Tiger boot dvd.
After scanning these forums I learnt that the PMU may need resetting, so I did that, the actual pressing of the PMU didn't move it much so I hope I pressed hard enough, and turned it back on agin only to be met by that same blank screen.
So is my faithfull iMac G4 dead?
iMac G4 17" Mac OS X (10.4.8)

Try things in Apple doc.#106464 for your startup issue.
Also, try using Disk Utility to repair your startup disk (hard drive) as shown in Dr.Smokes Resolving Disk, Permission, and Cache Corruption. Smokes link will help walk you thru it.
Let us know if Disk Utility reports any problems and what they are.
Cheers!

Satellite L450D - blank screen at start-up

Hi
my laptop shows a blank screen totally black on start up the hard drive light is not flashing but I can hear the fan.
Suggestions welcomed

Sounds like a serious hardware problem.
You can check if the issue is related to the display or graphic chip.
Connect external monitor and check if something would be visible on the 2nd monitor.
In case nothing would be visible on the external monitor, your graphic chip (maybe motherboard) is affected

Hp Omni 100 5050 blank screen on start up

2 days ago I put my PC in sleep mode and when I went to get back on it was unresponsive with mouse and keyboard. The light near the power button was on, but I powered down and powered back up and PC powers up, but now the light near power button is not working and neither my keyboard or mouse. The light is on where power cord is plugged in back of PC and where you can insert a CD/DVD light working. I have tried the Bios resetting from the forums troubleshooting no go. Power cord good and tested keyboard on another device and that is working. Not sure what else I can do? Any suggestions on possible fixes would be great! Thank you

Imovie 09 - blank screen on start up

Brand new issue. Never had a problem with imovie before.
Recently updated to newest version 8.0.3 (802).
Now whenever I open imovie I get a blank screen. Tool bar is present at the top but I cannot see any of the work areas until I click new project. Then it seem to appear from the top right corner. Only to disappear again to the top right. I thought it had something to do with expose or having a firewire drive plugged in. Anyone have a similar problem? HELP? any advice will be appreciated!

Its almost as though the program is fully active. But it's sucked out of view.
I'm able to see the work area if I hit the "show all windows" or F3 on my apple keyboard. But as soon as I click the window it gets yanked into the top right of the screen, gone from my view.
I was able to get half the work area to stay in view long enough to export my events to an external HD I'm anticipating not being able to use the program.
This is sooo frustrating because I've used imovie since forever and NEVER had a problem like this. I've run anti-virus, checked screen-size settings, un-installed and re-installed imovie, then updated still nothing.

MBP with solid state drive blank screen at start up

Hello,
I plugged in a USB 3 drive last night, the cursor changed shape into a blurring rectangle about 3 cursors wide that looked like a slot machine and wouldn't do anything else. I shut the lid, opened up and same. Shut it down and it won't get past a blank screen. It won't go into target mode.
MDP 13 inch with retina display Solid state drive. Help?
Mark

I took the non optical drive MBP into Genius Bar at Apple Bridgewater, NJ. The guy was very well trained in how to make a logic board crash seem normal. It was applaudable. Seriously. Really good service. "Mind if I plug this into our system?", "Hmm, Let me try this drive" "Well, it did get on our system, let me run this diagnostic". "Look, your hard drive is there, that's a good sign".
Me "Yes, but what is that red check mark next to power + - 5 volts?"
Him, "Yes, do mind if I take this in the back and look inside?"
Me, "Sure".
On his return," So the inside looks very clean, no problems there but this looks like it might be something that we would like to send to our repair facility in Tennessee. You see, if we put in one part and it doesn't fix it, we'd have to wait for another one. So we like to send these to a place that has all of the parts"
I got it back in 4 days. New logic board, new SSD. Ah, the joys.
Thanks for the responses, especially the SMC info and the PRAM reminder.

Brand new mac pro has blank screen on start up...why? Can here instructions but can't see

I hae a brand new mac pro and the screen is blank during start up. ***...I can here instructions but can't see screen.

That Mac comes with 90 days free phone support from trained Applecare reps. You should take advantage of it.
Another alternative is to make an appointment at the Genius Bar and have them put their hands on it.
Be sure you do something before your 14-day return/exchange (if you bought it direct from Apple) expires, or you may face a 3 to 5 day repair cycle.
Shine a bright light at the screen when it has booted up.
¿ Is the picture "there" but not lit up? that could be a backlight failure.
The F2 key is used to turn up the brightness, if it accidentally got turned down low.

Dv 6000 blank screen on start up

I have a dv 6000 running Vista. Earlier this week I ran a Microsoft update before turning off the laptop.
Now when I try to start up, the LEDs for DVD etc come on, you can hear fan noise and disc sounds, but the screen remains blank. After maybe 15 seconds the system shuts down but then automatically restarts, but the screen is always blank. This automatic shut down and start up cycles 2 or 3 times, then the computer automatically powers off.
Is there any help for this laptop, to get it restarted?
Thanks.

Are you able to enter the BIOS with a single memory module installed?
If so, can you test the module(s)?

Blank screen on start up yikes!

I recently have had some serious issues with the old bean.
I've had problems in disc utility for some months. Every time I tried to verify/repair disc it would never make it all the way thru, saying there was a disc error. It still seemed to work ok so I just kind of forgot about it.
Anyway recently it won't even boot up. I've tried resetting the PRAM, it makes the chime okay, I've done it repeatedly- no change. just a blank off white screen. I've thought about starting up from a disc but my disc is from last year and it's version 10.4.3. I currently have downloaded 10.4.7 version on it. Should I still try to start from my old disc?
Also I hooked it up to another newer laptop with a firewire and it shows that they are connecting. I tried doing disc utility from the new laptop and it showed the disc to stillbe in error. Do I need to erase the disc? umm. what should I try? Is there a danger to the newer laptop if I try and make repairs via the firewire? help! tahnk you!

I just had the same thing happen to me, and now my computer is in the Mac hospital which is raping me at 75 bucks an hour for data recovery.
Not to say our problems are exact... I'm just sayin.
Here's a situation for the Mac folk to address: They're holding my entire computer hostage. They refuse to put a new hard drive in and keep the one they're doing data recovery on unless I pay for it, in which case the hard drive will be third party and will not be covered under my AppleCare Warranty. The hard drive is screwed, no matter what. I don't understand why they can't have Apple send them a new hard drive, pop it in my G4, give it back to me, keep the corrupted one until its fixed or at least until the data is recovered, then send it back. Its Melrose Mac, an authorized Apple dealer and repair shop. I don't get it. I can't wait 14 BUSINESS days for a diagnosis to tell me how much longer its going to be before I get my computer back.
Suggestions?
PS, sorry chad, I totally stole your thread.
