No signal from 2009 MacMini to new Viewsonic vx2450mw

I just purchased a 2009 MacMini that worked with a monitor at the dealer. Brought it to the office and connected to the new ViewSonic monitor. Startup chime and LED on, but monitor says no signal. I am using a new Apple cable from the Mini video output to the VS DVI port- all connections secure. I don't have another monitor to test with.
Anything else I can do to troubleshoot at this point?

Does your Viewsonic monitor have an HDMI input? I use a 1080p HDMI Viewsonic with my 2007 Mac Mini and it works great. I would think a 2010 model would be fine.

Why is imported video from 2009 moving to new year after restarting Imovie?

We have successfully imported video from 2009 in a series of events; all seems to be working fine until we close out of imovie and return -- and then the events have moved to a new year (2011). When we click on the event that has moved to 2011, we get the message "no matching video". The video is on the hard drive; I tried to use "import video", but it is not recognized. This isn't happening systematically - just some clips from the same miniDV tape. Any ideas? thanks!

Will a MacBook Pro case from 2009 fit my new MacBook Pro?

So I just bought a new 13" MacBook Pro w/o retina display from Apple and there's a case I'm looking to buy for a 13" MacBook Pro w/o retina display, but the case was made in 2009. Are there any structural differences between the two? Can I still use this case?
Thanks for reading, please let me know!

That will fit the latest model. I stand corrected.

I have a MacBook from 2009. It is a 3.06 GHZ Intel Core 2 Duo. I am considering getting the new MacBook 2.7GHZ i7. Is that better?

Not even close - 3.06GHz is a dual core - 1066MHz system bus.
2.7GHz = Quad Core - 1600MHz system bus.
Which do you think is faster?

New monitor can not detect signal from new referb pc

Monitor is a new flat screen,  model 2310m full HD with  vga, hdmi, and dvi-d connectors and boot up CD which includes pdf manual and video drivers etc..
        PC is a referb Pavilion M9200t first time started since referb with a G-Force GT graphics card (1 gigabite) and dual DVI-D connections. No VGA or HDMI out. OS is vista ultimate that I will probably update to windows 7 if I ever get it set up. Monitor does not get a signal from new PC with DVI-D cable or a VGA cable with an adapter. Monitor works fine with my old XP PC after installing drivers and using the vga cable. New PC has no VGA out, so I bought a VGA to DVI-D adapter thinking that it would have proper drivers for a VGA monitor with no success. I also tried new PC on my old monitor with the DVI-D adapter on the VGA cable and that didn't work either. I can't do a first run setup without a monitor and the monitor won't work without a signal.
       I bought the PC from a friend who decieded to buy a laptop instead and had never started it. He bought it from someone who was selling referbs on E-bay and messed up and accidently started the warranty period or so they say.
        Also when I plug the PC in the fan starts and continues running till I do a hard shutdown, that is holding start button down till the PC shuts off. If I unplug and replug the computer it starts again without pushing start button. Does anyone think it is the graphics card issue or maybe power supply, or just not booting at all?  Any ideas would be greatly appreciated.------Thanks in advance.----Larry

            Ok, thats the procedure I was talking about earlier. I did that bios default factory reset just now. First the version 6 and earlier. It didn't work so I tried version 7 and later and that didn't work. I then tried version 6 and earlier again only this time pushed F10 more rapidly and got right in right when I got to the F5 and enter portion. Then I pushed F10 again to save the change and enter again to close. The PC didn't boot up the next screen like the test said it would. So I did it all again and spent some time reading what was on the bios pages but accidently pushed ESC as the bios menu suggested instead of enter to close out   . No boot up screen again. I did another hard shutdown and then unplugged the cord for 5 minutes and this time the PC stayed off when I plugged it back in. The bios are set to default but I cannot get it to start again in safe mode or boot up. So if the power supply is working properly, and the monitor worked in safe mode, then the video card must be good. right?
          So I'm editing from the night before, its Monday morning here in Wi. and I'm sorry to say that after leaving the PC unplugged all night that when I plugged it back in this morning, the dumb thing started again without pushing the  start button.  So the only thing doing a recovery on the bios accomplished was to prove that my the video card can run the monitor in safe mode which is a good thing I guess. Hope someone has an idea as to what else I can try.-------thanks

I am having trouble sending an audio signal from my computer (mac pro early 2009) to my TV. Is there some interface or adapter that allows /enables the audio input from my computer to be sent to the TV (R,L signal?) any suggestions

I am having trouble sending an audio signal from my computer (mac pro early 2009) to my TV. Is there some interface or adapter that allows /enables the audio input from my computer to be sent to the TV (R,L signal?) any suggestions

just the audio, eh?. If you were using DVI or DisplayPort that might be different, but for audio alone, it shouldn't be that hard. Just grab a 3.5 mm stereo plug to 2 rca cables adapter. Plug the smaller end into the back of your Mac Pro (or the Front), where you see either the headphone or speaker icon). Alt-click on the speaker icon at the top of your screen to show all audio inputs and outputs. Make sure it's set to Line Out. Plug the red and white end into the audio in jacks on the back of your tv and set it to the correct input. I don't know if your tv will allow just the audio to play. Usually one has to connect up something else, but hopefully I'm wrong. If you were using DVI, or DisplayPort, you'd need an active DVI--HDMI adapter or a DisplayPort to HDMI adapter, but
I don't know for sure

My Ipad will not receive signal from new home Xfinity modem. I reset Pad but still doesnt work.

My Ipad will not receive signal from new home Xfinity modem. I reset Pad but still doen't get WIFI

Does it not show the presence of a wifi signal, or just not connect?
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

What can I expect of my 4s with wifi connectivity. My 4s receive a signal from the same router I have always used. My 3G would pick up a signal throughout the house, and my 4s won't allow me out of the room. Is my new phone defective or just inferior.

4S at my house have stronger antenna than 3G iPhone. Reset Network Settings, tap Settings App>General>Reset, near bottom>Reset Network Settings. If still problem take to Apple for Warranty Coverage.

Mac not detecting signal from new Belkin N1 Router

Hi folks, my airport base station just "popped" yesterday and so I had to get a quick replacement here in Panama. Bought a Belkin N1 Router and I'm connected to it right now via ethernet so I know the modem is working fine and apparently the router is, too. I'm using the ethernet cable because my Titanium Powerbook (as well as my Toshiba notebook and iMac G5) aren't able to detect a signal from the router. I've spoken to three different Belkin people and they're pretty clueless as to why this is happening. I tried running the CD that came with the router but that isn't helping. Any ideas?
Thanks,
Raymond
PB G4 Titanium Mac OS X (10.4.10)

Hey guys, I got it working just fine. Now all three machines read it. Belkin has an email support page and I sent them a message detailing my issue. The next day one of their technicians sent me an email with instructions on how to get this working. Got it set up in 3 steps! I wish the manual had these instructions but it wasn't really a manual at all; just a card with small type on it.
FYI, here's what they told me:
To resolve the issue please follow the steps given below for configuring the router:
- Connect the computer to the LAN port on the router and connect the modem to the Internet/WAN port, using Ethernet cables.
- Take a paper clip, insert the paper clip on the reset hole of the router and then hold it for 15 seconds.
- The power light will flash and then come back ON solid, indicating that the router is being restored to factory defaults.
- The corresponding lights on the front of the router should be lit up.
- On the computer, check if you have an IP address in the range of 192.168.2.x
- If not, specify a static IP address, gateway and DNS by following the steps at
http://web.belkin.com/support/kb/kb.asp?a=2824
- Log on to the router web interface at http://192.168.2.1
- By default, the password is blank.
- Click on Connection Type in the left hand column under Internet WAN heading.
If the connection type is Dynamic (cable):
- Click on Dynamic and then click on Next
- Type in your “Hostname” if you’re Internet Service Provider has provided it. Else, leave it blank
- Click on "Change WAN MAC Address".
- Click on the button "Clone".
- Click on Apply Changes
----at this point, the problem was solved----
If the connection type is PPPOE (DSL):
- Click on PPPOE and click on Next.
- Enter the user name and password given by your Internet Service Provider
- Save the settings
- Click on the Home link at the top of the screen
Internet Status should show Connected on the top right hand corner of the web page.
On the wireless, associate wireless following these steps:
-Open the wireless connection icon from the system tray
-Click on Advanced button and click on Wireless Networks tab.
-Remove all the networks under "Preferred Networks" and Click on `Refresh` under the Available Networks
-Select the available network and click on Apply or Ok
Then, check the IP address of the computer. For checking the IP address:
- Click on start & click `Run`.
- Type in cmd & click `ok`.
- Type IPCONFIG and Enter. Check for IP address, subnet mask & Default Gateway.
- The IP address should be in the range of 192.168.2.x (x=2 to 254)
- If not, specify a static IP address, gateway and DNS by following the steps at http://web.belkin.com/support/kb/kb.asp?a=2824
- In the command prompt type PING 192.168.2.1 & Enter. You should get replies.
- Type, PING 4.2.2.2 & press Enter. Check if you are getting replies.
- Try pinging yahoo by typing PING yahoo.com and Enter. You should get replies.
- Then try connecting to internet.

I'm trying to hookup my new AirPort Extreme with my net gear 7550 router/modem from Frontier. I'm not getting a wifi signal from the airport. What am I doing wrong?

What am I doing wrong?

I'm trying to use AirPort Untility to configure the old APExtreme to extend the network, but it won't let me.
"Extend" is only used if the two AirPort Extremes are connecting using wireless only.
"Create" is the correct setting to use since the AirPort Exremes are connecting using Ethernet.
Configure the second AirPort Extreme to create a wireless network using the exact same wireless network name, same security setttings and same wireless password as the "main" AirPort Extreme and make sure that you are choosing the Bridge Mode option for the second AirPort Extreme before clicking Update to save the settings.
When you do this, everything will act like one big wireless network and computers will automatically pick up a signal from the AirPort with the strongest signal based on their location.
This Apple document more details on this....which is called a Roaming Network.

Hi, I try to conect Mac Mini from 2009 with my HD Tv Samsung F 6400 . With Mini Dvi conection and adapter to HDMI input in TV I got picture but not sound! I have analog cable from the phones out from mac but imposible to conect to TV? Can you HLP?

You really need a newer Mac Mini with a true HDMI output, because that Mac Mini's DVI output does not support Audio.
You might try a 3.5mm to RCA adapter
from the Mac Mini's headphone jack to the TV's audio input,
but that would require being able to select the Audio input in the TVs menu while using it's HDMI input.
Optionally you could also use an external 2.1 Speaker System or patch the audio from the Mac Mini to your home stereo system to enhance that older Mac Mini's audio.

Wireless signal from iMac to TV?

I have a new 20" iMac G5 isight on the way and have a question. Has anyone tried to hook up the iMac (or other mac) wireless to your TV. There is products like this www.amazon.co.uk/exec/obidos/ASIN/B000068TYR
ref=erra_acc_dp1/026-6032989-4654855 that will send a signal from your antenna to your TV wirelessly. I thought mabye in combination with a TV tuner like EZ there would be a way to get the signal from the mac to the TV. That way I dont have to drill a cabel-hole in my livingroom floor down to my office to enjoy FrontRow on my TV. Or is there any other solutions/suggestions?
(And i dont think there will be an Airport Express A/V launched next week... though I wish!)

You should be able to connect your ATV directly to your iMac using Internet sharing, but you can't use the same NIC that the iMac is using for its connection. If your iMac is connected to your router by wi-fi, you can share the Ethernet port with the ATV. If your iMac is connected to your router by Ethernet cable, you can share your iMac's AirPort with the ATV.

Getting Started with Labview.pdf ‏901 KB

Hi Ashwin,
It is a good idea to first be able to communicate with the microcontroller using some sort of serial communication software such as "HyperTerminal" or "Procomm", etc. Refer to MicroChip's recommendations on this.
Once that works, then you are ready to use LabView.
Here is a link which covers many aspects of serial communication. Link - click here
You probably received a development kit. They usually have a readily available interface. It's been a long time since I played with the PIC, but I seem to remember that you need to program the serial communication driver (as well as at least a bootloader) to get the serial communication going. The driver contains the necessary protocols so that you PC can have a machine conversation with the target (PIC).
It sounds like a fun & interesting project. Please avoid to have replies to your personal email. By having the answers posted to this thread, you will get much more support and advice.
Have fun,
JLV

Hi Ashwin,
I am not familiar with the PIC Microcontrollers, but I am assuming you mean that you have the microcontroller sending out serial data that you want to read on another computer with LabVIEW. Please let me know if this is incorrect.
What type of data is coming out of the serial port? Is it ASCII, or binary? The reason I ask this is that the serial communication in LabVIEW is done through a protocol called VISA, which uses ASCII data to send and receive. You can later convert this data into whatever form you need, but this is what it is designed to read and write.
You can check the settings such as baud rate and data bits in a configuration utility called Measurement and Automation Explorer, or MAX. When you open up the MAX interface, you can expand the Devices and Interfaces entry on the left, and then expand the Ports entry to see your serial port. When you highlight this port, select the Port Settings tab at the bottom of the window, and you can see what the current settings are, and change them if you need to. You can also set these parameters in LabVIEW using the VISA Configure Serial Port VI.
You can also test communication in MAX by right clicking on the correct port and choosing Open VISA Session. Then choose the Basic I/O light blue tab, and then go to the Read tab. When you click execute, it should read in what is coming from the serial port. This will allow you to verify that the correct information is coming in before even trying to acquire the data in the LabVIEW environment.
In LabVIEW, the best resource to use the Basic Serial Write and Read example program that ships with LabVIEW. By examining the block diagram of this program, you will be able to see the basic programming flow of serial communication in LabVIEW.
I hope this information was helpful! Please let us know if there's anything else we can help with.
