23" Cinema Display not working. Please help!!!!
I recently purchased a dual 2gHz MacPro Tower and a 23" HD cinema display (both factory refurbished by Apple). Everything worked flawlessly. Then...
I was away from my computer for about a week, during which time both the computer and the monitor were powered down the entire time.
Now my CPU boots fine, and I can hear it responding (when I raise and lower the volume, etc.) but the ACD won't fire up at all. The light on the front isn't blinking or anything, and I'm just wondering if there's anything I can do (I've already reset pram, replugged everything in, restarted several times, etc).
I've also done the ULTRA obvious stuff like brightening my display (which does nothing). I don't know how a less-than-a-month factory refurb that's been off for a week could go kaflooey, but any advice is greatly appreciated.
I'm having a similar problem although it may be USB related. It started with my 2 year old 23" display not waking up when it and the computer (3 month old 15" Mac Book Pro) were asleep overnight. The first two nights this happened I'd restart everything and it'd all be fine. The next couple nights I noticed that if I just unplugged the USB cable from the display into the computer, it would all wake up and function just fine. Today (the 4th day or so, and the day I finally have time to research what the problem might be) the display won't start up at all. There is no indicator light (and never has been in these situations) on the ACD. According to my Display menu bar and my system profiler, my computer definitely recognizes that the monitor is attached (although this was not true the first time the ACD acted up). My mouse also acts as thought the ACD is online... I have now adjusted brightness, and unplugged absolutely everything and replugged it all into a different power source. Still no go... Haven't had a chance to buy a new brick, not really sure that'd work for me... any ideas?
If it were the brick- based on what I've seen on the back of my ACD, it doesn't even look like you can disconnect the cord?
and just a side note... in exploring this problem i noticed that you can choose what the power buttom on the ACD actually controls in the Options menu of the Display System Preferences... is this only for older OS's? because my display preferences has absolutely no Options menu in it...
Thanks.

New Apple ipad air display not working,please help?
Please can anyone offer help? Week old ipad air display has stopped working after app froze and son double tapped home button to shut app down.Thank you in advance for any offers.
If you are editing/testing in the Flash editor, the html end of things is nothing to be concerned about at this stage, and will likely take care of itself when it comes time.
So you run the file in Flash and do not get any error messages? Then place a trace command inside the button's event handler function to see if the button is communicating with it....
function b_1ClickHandler(e:MouseEvent)
trace("button works");
navigateToURL(new URLRequest("http://www.MYURL.com/.html"),"_self");
Also, I'm just noticing you don't have an actual file named in the url, so in case the "not working" is that you can't get the desired page to show, that may be the cause. Normally I would suggest testing url links online rather than in Flash because it's iffy to try to get the web involved with the editor at times. -

I have 4s iPhone , I download the iOS 7. Now the front receiver microphone is not working , please help me that how to fix the problem.
I live in South Africa, and I had the same problem with my iPhone 4.
After weeks of frustration and swearing, I was in the process of restoring my phone to a previous iOS. To do that you need to turn the "Find my iPhone" option off, since i turned it off, my problem was solved. No need to repair anything or revert back to old iOS.
***** that i cant use Find my iPhone, but atleast i can use my phone. -
I installed windows 7 on my macbook pro. all is working but lan adaptor and sound od laptop is not working. please help me or send the link where i can download the these drivers.I have lost my resource cd .
If you are running Lion or Mountain Lion, the drivers are downloaded from within Bootcamp Assistant. If you are running Snow Leopard the drivers are on your Snow Leopard install disk.
Read the Bootcamp Install Guide for your version of OSx. http://www.apple.com/support/bootcamp/
Bootcamp questions should be asked in the Bootcamp forum where the Bootcamp gurus hang out https://discussions.apple.com/community/windows_software/boot_camp -

while updating 4.0 version to 5 version system shows sim card is not valid. My iphone is not working .Please help me
I would imagine your iPhone was hacked to make it work on your local carrier.
Updating the iOs to 5.xx will lock it back to the original carrier .The carrier holding the lock are the only
entity able to authorise the unlock .You will have to contact them and see if they unlock and the terms the apply -

The built-in mic in g50 122ca laptop model is not working. please help me out.
the built-in mic in g50 122ca laptop model is not working. please help me out. OS: Windows Vista (32-bit)
here is a sample code .
so far you procedure looks good but
i bet you have to specify the name of report , instead of 'filename'.
see this
Plist_id := GET_PARAMETER_LIST('P_name');
IF NOT ID_NULL(Plist_id) THEN
DESTROY_PARAMETER_LIST(Plist_id);
END IF;
Plist_id := CREATE_PARAMETER_LIST('P_name');
ADD_PARAMETER( Plist_id, 'P_Receive_date', TEXT_PARAMETER, TO_CHAR(Receive_date,'mm/dd/yyyy'));
ADD_PARAMETER( Plist_id, 'P_Hearing_date', TEXT_PARAMETER, TO_CHAR(Hearing_date,'mm/dd/yyyy'));
ADD_PARAMETER( Plist_id, 'P_Hearing_time', TEXT_PARAMETER, TO_CHAR(Hearing_time,'mm/dd/yyyy'));
ADD_PARAMETER( Plist_id, 'P_Issue_date', TEXT_PARAMETER, TO_CHAR(Issue_date,'mm/dd/yyyy'));
ADD_PARAMETER( Plist_id, 'P_Workshop_date', TEXT_PARAMETER, TO_CHAR(Workshop_date,'mm/dd/yyyy'));
-- RUN_PRODCT(REPORTS,'..\Reports\Pro_License',SYNCHRONOUS, RUNTIME, FILESYSTEM, Plist_id, NULL);
-- here Pro_License is the name of report.
did you tried to see if the parameter passed using a message ?
try
message('parameter name'); pause; write this before "run_report". -
