PB display completely black, but only sometimes. Any thoughts?

The computer is an older PB G4 Titanium 500Mhz. Currently running OS X 10.4, though I am in the process of a second erase and installing 9.1 that came with it.
Out of nowhere last week the screen just froze, on restart it was completely black. But after turning it on and off a few times the screen will appear, but it will freeze within a half hour or so of use. I have erased the drive and reinstalled a new system, ran the Hardware Test, replaced the battery(as it wasn't holding a charge), and the power cord which was showing signs of wear.
I don't believe it is the inverter as the screen is not even faint, it's completely "off". The only thing that I am able to do on a consistent basis is start up from the installer CD. This is what leads me to believe it's not the display itself. But at this point I am beyond baffled.
Anyone encounter a similar issue or have any idea what could be going on?

Apologies, wrong board.

Laptop screen goes completely black but shows that it's still on

Hello everyone, i'm in need of serious help!
I bought this laptop over 2 years ago (October of 2008 to be somewhat exact). It's a Windows Vista Home Premium, with service pack 2.
its an HP pavilion dv7 notebook pc
processor: AMD Turion (tm) X2 Dual-Core Mobile RM-70 2.00 GHz
Ram: 4GB
system type: 64-bit operating system
im assuming the video card information are as follow:
name: ATI Radeon HD 3200 Graphics
chip type: ATI Radeon HD 3200 Graphics (0x9612)
DAC type: Internal DAC (400MHz)
total memory: 1914MB
memory: 3836MB RAM
page file: 2163MB used, 5732MB available
current display is 1440 x 900 (32 bit)(60Hz)
directx version: directx 11
with that being said... here's my dilemma...
Each time i play the video game, "World of warcraft", my laptop's screen goes completely black but it shows as if though it is still on. I can't see the screen but it shows that it is still on by the little lights on the bottom of the screen.
I took my laptop to a family friend who knows a lot about computers to see if they can fix it for me. They told me that everything was running fine, everything is okay, the ram, memory, graphic card, everything passed the test, and it was not over heating... there was nothing wrong with my laptop. They THOUGHT it could be the motherboard, so they tried it, but in the end, it wasn't. Unfortunately the problem was not solved.
I played World of warcraft on this laptop before. When i first bought it. It ran smoothly and gave me no problem whatsoever. I'm clueless is to though why it's giving me problems NOW.
Could anyone please please pleaseeeee help me? i have given up already. I have done everything i could. Please help me! i believe i have done a total one 1 or 2 system restore to factory settings, the 2nd one was recently (probably a month ago) and i'm not sure if maybe perhaps i needed to DL something else? i have DL all the updates that microsoft offered to me when needed and when it was necessary, but this particularly problem was never fixed.
someone please help me! Thank you so much!

erichon99,
I think i may have found MY solution but i have yet to test it out... No one helped me. No one at all. I took my PC to a family friend company and they did everything for me: ran tests to see if my laptop is up to date with everything, removed graphic card and put a better one and nothing still. They thought it was my mother board but they ran tests again and everything on my laptop past the test. My graphic card was fine, ram was perfect, memory was perfect, everything everything on my laptop was perfect. They couldn't find out what was the problem. I took it to best buy and not even them could help me. When i was about to give up, my fiance, he did some research and found this guy on youtube who does LIVE recordings and answers people's questions. My fiance asked the question and he got serveral responses. Out of 10, i would say about 2 or 3 of them mentioned, "it's the power cord" the rest said it might be virus, or a card is not working properly, etc. You can give it a shot (buying a new power cord) those who told my fiance that it could be my power cord, said to get those power cord that has a fan in them.
I think this makes sense because my screen goes black only when i'm playing a game. even when i play cityville on facebook it goes that black screen, but it doesn't go black, it does that pixelated, rainbow, warning bar, thingy (i hope you know what i mean lol) and when i touch my power cord to my laptop it is BURNING hot. What i do is, when my battery is fully charge, i disconnect and play my game, and to not lose any docs i left open, i close my games, and plug back in. I've been lazy to find another power cord lol i guess i should start now, huh? lol
i hope this help. I would say (if you've done everything like how i did) buy a power cord that matches your laptop, but with a FAN in it (i was told it's the best and you'll never have that problem of freezing or whatever)

Macbook air charges fine with the Thunderbolt screen connection but only sometimes with the 45 W chargers.

My Macbook air charges fine with the Thunderbolt screen connection but only sometimes with the 45 W chargers. It seems to be the combination of the chargers and the computer. I was thinking whether the Thunderbolt screen has a larger power supply which easier activates the computer to actually receive the charge. It reminds me a bit of the Nokia Lumia 800 telephone, which when totally exhausted needs a strong charger to be activated again. I am as frustrated as most others. I have got two chargers, and both of them sometimes work, other times not. Sometimes, they start working after a while. Is Apple meanwhile coming up with a solution or advice how to handle such situation?

I just got my ATD and late 2011 MBP up and running. I've not tried running without the power adapter from the ATD plugged in, but I just tried and didn't have any problems with the display not waking. You may want to take your query to the ATD forum - https://discussions.apple.com/community/peripherals/thunderbolt_display - perhaps someone there has experienced a similar issue.
Good luck,
Clinton

TV Out Issue- No display of screen but only the audio sound can be heard

I have alway being using my iPhone 4 to watch my video/ mirroring by connected to TV (Sony) through 30-pin digital AV adapter, but after the upgrade of software to version 6.1.3 (10B329). During TV out, showing no display at screen but only the audio sound can be heard at background. Appreciated if there could be a update to fix this issue.
Thank you
Regards,
Devil38

Thanks you. Problem is solved. The cable wasn't plugged in properly.
In spite of video rendering smoothly, audio started coming only when I disconnected the cable and plugged it in hard.
Perhaps I was pampering my phone too much

I am not getting any sound with my apps, only itunes, any thoughts?

I am not getting any sound with my apps, only itunes, any thoughts?

Have you got notifications muted ? Only notifications (including games) get muted, so the iPod and Videos apps, and headphones, still get sound.
Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and it's the icon far left; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085

Thunderbolt display not recognized - but only after supper!

Ugh. Getting seriously frustrated with my 27" TB display, now. Have been using it on a MBP 2011 for a while, had experienced some flickering with Lion, not so with ML.
Last week, I left my MBP connected and went in for supper; when I came back, the MBP had - of course - fallen asleep. Woke it up, but only the MBP display came on, not the TB display. I unplugged/replugged, several times - same thing.
Rebooted the MBP, with the TBD plugged or unplugged - same thing.
SMC reset - same thing.
I spent two nights reading forums and trying all sorts of fixes - no luck.
Finally, I resigned to booking an appt with the local Apple Store; this appt was for this morning. This morning, before getting the monitor out of the office, I decided one more time to connect my MBP - it worked!!! ***?
So I worked all day, no issues. Very happy.
Tonight, before going in for supper, I unplugged the monitor and closed my MBP's lid so it would go to sleep. When I came back, I woke up the MBP, connected the TBD, and...nothing. Black screen!! Went through a couple of rigamaroles to try and get it back - nothing!
Argghhh!!
So now, I'm wondering if my diet has something to do with it. Tonight, I had T-bone steaks on the grill, with roasted potatoes and a salad. Maybe if I would have had pasta instead the monitor would have gone back on?
Any ideas, suggestions or magic spells would be greatly appreciated.
As would a fix from Apple...

I have been having the same problem since I got the **** Thunderbolt display and a lion-installed macbook pro in September last year. I've been sitting tight thinking surely Apple will fix this debilitating defect on their premium equipment - How wrong was I!
My story is similar in that I always take the laptop home from work and have the Thunderbolt display in my office at work. I close the lid putting the laptop to sleep and pull out the cables. When I go home I may use the laptop via its internal display (one would think that would be ok) and then close the lid and put it back to sleep. WHen I return to work, plug in the cables and open the lid, most of the time the thunderbolt display stays black. On a rare occasion it will switch on but I can't fathom any pattern as to when and why it might work. The only solution to get the display to switch on is to reboot the laptop (and lose all my open documents from work the previous day and night). Recently, and I'm not sure what has triggred it, things have got a whole lot worse. Now, if I reboot the laptop when connected to the unresponsive screen upon restart the Thunderbolt display freezes on a grey screen and the laptop display stays black. The only solution is to hold down the power button and force shutdown the laptop. This happens everytime now, I simply cannot reboot the laptop with the thunderbolt display attached!
Nice premium equipment Apple! As this stuff was bought by my work I have learned to live with it. If had bought this junk with my own hard-earned then I would be furious and would have demanded a refund/replacement/explanation a long time ago.
Maybe, just maybe, Apple may one day actually fix this £2000 setup I have sitting on desk so that it switches on when its supposed to. Is that too much to ask?

Display turn black, but computer still running

I woke my computer up from sleep mode to check my am email of mine. As I was about to log-in to my email online my display turned black. I thought the computer shut down completely, but I could still hear it running. I just shut down my computer with the button on the back of the diplay and then started it up again.
My computer seems fine now, but I was just wondering why that happened? I've had my computer for a few months now and I've never had this problem. I just installed new memory about a week ago..might that have something to do with this happening?
Thanks.

Intermittent faults such as that are difficult to diagnose at distance so the best thing is to get Apple / your supplier to check it over. Apart from the RAM there is nothing you can do to the electrical / mechanical side of an iMac. If it were a software problem it would show more regularly.
If you haven't already purchased it get AppleCare, that will cover the machine for 3 years from the ORIGINAL purchase date and as you are having problems would be a worthwhile investment. You must purchase it before the original 1 years warranty expires.

I reloaded my old iWorks 08 to my iMac's new hard drive. With a new Pages document, I can't see the cursor. You can type in text but it is in white only. Any thoughts?

Hi. I lost my iMac's hard drive and had a new one installed. I reloaded my old iWorks 08 software and then transferred my Pages documents from a portable HD to the iMac. The files open but the original text in them (they are journals) are in white against the white background. Plus I can't see any sign of the cursor. I can hi-lite the text and change its colour but never to black. Plus the photos I inserted along side the text are barely visible, as if they had been badly faded.
Any thoughts on this? Many thanks.
Richard

Richard,
You must run Software Update and bring your old iWorks 08 to the latest release for compatibility with the current OS.

My screen is going black and the phone acts as though it is on and everything is working but I can't get the screen to change from being black... Any thoughts?

I have had my Droid 2 for about a year and a half now. I had no problems with it until a few months ago when that update came out. All the sudden the phone would freeze up then all of a sudden yesterday I was texting a friend and had the keyboard open then the screen went completely black. I tried rebooting the phone...pulling the battery... and then doing a hard reset... Nothing works. I cant even really do a hard reset because the screen is black. Any thoughts?

We have two Ipad2's in the house 64gb wifi, one prints wirelessly the other sees the printer but no results, any thoughts!

We have two Ipad2's 64gb wifi in the house, one prints wirelessly the other no results even though it sees the printer, any thoughts, also while recently overseas the IPad having print difficulties also had wifi connection issues although no problems at home, any thoughts?

Kristeen-
In case the printing problem is related to the WiFi problem, try resetting your iPad's WiFi network. Go to Settings-General-Reset-Reset Network Settings. You will probably need to reconnect the iPad to your WiFi.
It is also possible that there is a print job hung up in the Print Queue. Double click the iPad's Home button and a row of recent Apps will line up along the bottom of the screen. Scroll across and look for the Print Queue.

HT3924 Target display mode connects but only displays desktop background, no files or command lines

I have connected my early 2014 MacBook to a late 2012 imac and connected them via Thunderbolt cable. Pressing Command F2 causes the screen on teh iMac to change to teh MacBook background screen, but does not display any desktop files or command lines. Any ideas how to fix this?

Hi tdmone,
Welcome to the Support Communities! The resource below may help you with the Target Display Mode options for connecting your Macbook and iMac:
Target Display Mode: Frequently Asked Questions (FAQ) - Apple Support
http://support.apple.com/en-us/HT3924
The table below shows iMac computers that support TDM, the required cables, and the port of the computer to which you are connecting the iMac.

iMac (Mid 2011)

iMac (Mid 2012 and later)

Are you connecting via the Thunderbolt ports on both computers?
How do I enable TDM?
Make sure both computers are turned on and awake.
Connect a male-to-male Mini DisplayPort or ThunderBolt cable to each computer.
Press Command-F2 on the keyboard of the iMac being used as a display to enable TDM.
Note: In Keyboard System Preferences, if the checkbox is enabled for "Use all F1, F2, etc. keys as standard functions keys," the key combination changes to Command-Fn-F2.
Can I use a third-party keyboard or older Apple keyboard to enable TDM?
Some older Apple keyboards and keyboards not made by Apple may not allow Command-F2 to toggle display modes. You should use an aluminum wired or wireless Apple keyboard to toggle TDM on and off.
I hope this information helps ....
