Have you checked or unchecked the turn mirroring on in display preferences? Sound output settings: be sure you are set for internal speakers and not one of the other options (unless you are using USB or some other output device). This is not a hack: Hackers want to use your machine to send email or style your data. They don't care about monitors.
Also try repairing permissions in disc utility, and then repair the disc. If that fails, run Disc Warrior and clean up the system.

From your description the problem is the backlight going out in the monitor. Either the bulbs itself or the converter board. Both are worth about $35 and this can be a diy fix. Most people use this as an excuse to replace the monitor with something newer/bigger as the cost is not that much more and about the same if you have to pay labor to do it.

Why does my desktop pro keeps shutting down unexpectedly


Just to clarify a G5 is not a Pro or "desktop Pro" (Mac Pro is an Intel based machine). Yours is a "Power Mac". Install a temp monitoring app to see the temperature (mainly the CPU temps). Mine runs around 50 to 60 Celsius and never more than 72. If the temps run to high she will shut down. G5 are great machines but it's not rare for them to go bad. Power supply issues and liquid coolant leaks are well know. Fans controllers have stopped working (the fans them selves are usually OK).

Trouble connecting Insignia HDTV 19" to my macbook pro


One of the first things you may notice about your new big-screen HDTV is that it has more connections for video than your old TV ever dreamed about. It probably has two or three HDMI connections, maybe a DVI connector, a VGA connector, and at least one component video connection. And those are just the connections most commonly used for high definition.
It’s shame to let all those connections go to waste. Your Mac just happens to be sitting nearby; why not hook it up to your new HDTV? It's actually a pretty easy task. A few lucky souls won't even need an adapter; for the rest of us, at least one adapter will be necessary.
Pick the Right HDTV PortFor best quality, your HDTV's HDMI or DVI ports are the preferred connection method. Both are capable of the same digital quality. The only practical differences are the style of the connector and the fact that HDMI supports video and audio in a single connection.If it has one, another option is to use your HDTV’s VGA port. The VGA connection isn't as good as the HDMI or DVI method, but as long as your TV supports full resolution via the VGA port, you'll be hard pressed to notice the difference.Mac Pro, MacBook Pro, Mac MiniMac Pros, MacBook Pros, and Mac Minis have standard DVI connectors. Mac Minis and MacBook Pros have a single DVI port; Mac Pros have at least two DVI ports.If your HDTV has a free DVI port, then all you need is a standard DVD cable; no adapter is necessary. But in all likelihood, you'll need to connect your Mac to your HDTV using either an HDMI or VGA connection; both options require an adapter. If you choose VGA, you can use the adapter that came with your Mac.If you choose HDMI, you'll need a simple adapter, which is available from multiple sources. The adapter may be a cable with a DVI connector on one end and an HDMI connector on the other, or it may be a small adapter that has both types of connectors, but no cable. Either type will work fine.iMac, MacBookiMacs and MacBooks have a mini DVI connector for hooking up external monitors or TVs. You'll need at least one adapter, maybe even two. At a minimum, you'll need a mini DVI-to-DVI adapter. You may also need a DVI-to-HDMI or DVI-to-VGA adapter, depending on which port on the HDTV you choose for the connection.Make the ConnectionOnce you determine which, if any, adapters you need, and have the necessary cable to reach from your Mac to the HDTV, turn off both the HDTV and the Mac. Connect the cable between the Mac and the HDTV.Turn the HDTV back on first. It doesn't need to be set to the connection the Mac is on, but it must be powered up first, so that when it boots, your Mac can recognize the TV and the resolution it needs. Once the HDTV is powered up, turn on the Mac.Your Mac should recognize the format and resolution of the TV, and automatically select the native resolution of the TV for running the video. In a few seconds, you should see the Mac desktop on the HDTV.Over or UnderscanYou may notice that the Mac's desktop appears to be slightly larger than the HDTV's screen (its edges are cut off); this is called overscan. Or, you may notice that the desktop doesn't occupy all of the HDTV's screen real estate (there are dark areas around the edges); this is called underscan.You can usually correct either issue by making adjustments on the HDTV. Check the HDTV's manual for information on making scan-related adjustments. They may be called overscan, underscan, dot-by-dot, or pixel-by-pixel. If your HDTV has a dot-by-dot or pixel-by-pixel capability, give this a try; it should eliminate any over or underscan issues. Some HDTVs only offer these special scan controls on specific inputs, so be sure to connect to the corresponding input on your HDTV.Time to Watch a MovieOnce you have your Mac and HDTV working together, it's time to kick back and watch a video from your Mac. Be sure to check out the QuickTime HD trailers for a sense of what HD and your Mac is capable of. Enjoy!

I have a new mac pro and I am trying to use it with a Dell LCD projector. It shows the homepage without any text and won't show anything else.


What do you mean by "shows the home page"? What home page?
Normally you will see your mac's desktop (or, on some models) you will see your desktop background without any icons. If that happens the projector is acting as an extended screen.
If you want to project exactly what you see on the laptop's make sure that mirroring is switched on in the monitors panel of system preferences.

Damaged 24 iMac screen - want to use ext monitor via "mirroring" in screen preferences, but cannot access system preferernce due to damaged screen...any suggestions


There is an elegant way to solve this, but it requires another compatible model Mac.
Boot the damaged Mac into FireWire Transfer mode by holding down the "T" key immediately after hearing the startup chime. Attach a FireWire cable between the two Macs. Start up the other Mac by holding down the "option" key after hearing the startup chime. Choose the startup drive from the broken Mac. Now your good Mac is booted off the drive of the broken Mac, and any configuration changes you make will be made on the hard drive of the broken Mac.
Attach the external monitor temporarily to the good Mac. Open System Preferences and set the monitors up in mirrored mode. Shut down the good Mac. Then hold the power button in on the broken Mac until the power turns off, and remove the FireWire cable.
Now move the external monitor to the broken Mac and boot it. It should come up in mirrored mode.

Bought and HDMI to DVI Cable, Not Fully Functioning


Your setup is probably in "extended" mode - if you move the mouse back in forth, when it leaves the Mac Pro screen you should see it on the external plasma monitor. You can switch to "mirror" mode if you want to see the same thing on both screens. Or put the computer into "sleep" mode, close the lid, connect an external keyboard and the plasma display and wake it up by pressing keys on the keyboard. Then you should see the desktop on the monitor.

Is the mirroring still taking place or just on the one display.  If it just on the Macbook, go to the display settings and select the arrangement button, there should be a mirror button there.
