Mac wont connect to tv :(

Hi, I am trying to connect my mac mini to my lg tv, its an lg22ls4d.
i know the tv can be used as a monitor and that it works because i connected my dell laptop to it.
does any one know why its not working??
thanks!

If you have a wired usb keyboard handy, I'd try starting the Mini in Safe Mode -- by holding down the Shift key as soon as you hear the startup chime or beep. This should start the Mini in a basic resolution that most displays can handle. And that would allow troubleshooting.
The Shift Key needs to be held down for about 30 seconds. And this won't work with a wireless keyboard or the Apple Aluminum keyboard. Startup in Safe mode will be slower, and some features won't be available, like Wifi.
I'm not sure that Safe Mode will work, since you say that nothing from the Mini appears on the screen at first startup -- but it's worth a try at least.

  • My mac wont connect to the wifi network but all other devices are working fine! Please can you help

    My Mac wont connect to my WiFi.  It can see the network but has an "!" over the WiFi signal. My iPhone and Surface connect fine.  My Mac was working fine yesterday.  I've restarted the rooter, the Mac and still not luck.  I've changed the WiFi channel, removed and re-added the WiFi network, but I still can't connect. Please can someone help.... thank you !

    Power Cycle
    Power off the router. Unplug it from the wall. Wait a while.
    Plug it back to the wall. Power the router on. Wait until all the lights are lit properly. It will take a while.
    Restart the computer.
    Start up in Safe Mode.

  • My mac wont connect to my wifi.

    My macbookpro wont connect to my wifi, or any wifi for that matter, it used to be able to but then one day it just stopped, sometimes when i log into my acounts i find it connected to my wifi but then it will log out after 2 minutes. It might have been something i did to my mac (unintentionally) because my other computers are fine, does anyone have any suggestions?

    Hi thewhiteapple, and a warm welcome to the forums!
    See if this helps...
    Go to System Preferences
    Click Network
    Highlight AirPort and click Configure...
    Choose “By default, join: Preferred networks”
    Select your access point.
    Remove your access point with the minus button.
    Launch your keychain access in Utilities and delete your access point keychain entry.
    Reboot
    Go back to the “By default, join:” page and click the plus this time to add your access point. Enter the correct password, save, reboot.

  • MY MAC WONT CONNECT TO MY WIFI BUT WILL CONNECT TO OTHERS

    My imac wont connect to my wifi but will connect to the person downstairs from me. it works once and a while but never for more then a few mins...could it have something to do with the router?

    Hello Trey,
    Without knowing anything about your WiFI system, my opinion is that your wifi signal is either, weaker than your downstairs neighbor, or more likely, your wi fi system is suffering from interference.  The first thing you should do is change the channel it is operating on.  See if that helps.  
    I tend to think it is not the router, but can only offer a guess, since you did not describe your system.

  • HT201250 mac wont connect to time machine

    I was happily backing up my compouter to the time-capsule/time machine, and suddenly my computer wont back up or recognize my external harddrive. It wants me to reformat it and start as if it were new. I dont want to overwrite my content, so I am not sure quite what to do.

  • New mac wont connect to linksys WRT54G

    i have tried everything. restarted router, tried all the passwords, WEP keys with and without the $ signs in front. i get invalid password sometime, and sometimes i get could not connect to router. i would appreciate any help

    Start from scratch.
    Yell out the window and scream, "I am fed up, and I can't take it anymore" (optional)
    Plug the power into its socket
    Plug the Ethernet plug that goes to the Internet into the uptake, or Internet port.
    Hold the reset button for 30 seconds.
    Turn off Airport in your computer, if that is what your using, as you will need to use your eithernet port on your computer instead.
    Put an eithernet wire into one of the other ports on the router and connect it onto the computer.
    At this point, go to network preferences and copy the router number.
    Open a window or tab into eihter Safari or Firefox and paste the router number into the location. The http:// should be the only other item that you should see in the location bar.
    The password will be "admin"
    From here, you will put in the information that you will need, which should be what ever your ISP requires.
    Then before you do anything else, test it, first with the current connections. If that works, and you want to use the wi-fi, turn on airport, but make sure that you disconnect the Ethernet cord, as your computer could use that over wi-fi.
    If that works, bow , and say, "I am not worthy," three times.
    Put away your Ethernet cord and place offerings or sacrifices to the linksys.

  • Randomly my macbook wont connect to the wifi in my apt except for one area. I have tried everything. Help?

    My mac wont connect to the wifi in my apt. it will connect to other networks elsewhere just fine, however. All my other devices still connect anywhere in the apt. Help?

    The apt is very small. But i ran istumble and it said the router was giving around 64% and it appears as though no one around is using the same channel as us. Either way, if other comps can pick up on the signal, why isnt mine all of a sudden?

  • I just replaced the hard drive for my Mac Pro, and I am trying to restore what is on my Time Capsule, but it wont connect, and only is giving me the pinwheel of death. What do i do?

    I just replaced the hard drive for my Mac Pro, and I am trying to restore what is on my Time Capsule, but it wont connect, and only is giving me the pinwheel of death. What do i do?

    You will need to boot from some alternate boot device to accomplish this, if you did not initialize the drive before installing it.
    If you have another Mac, you may be able to use FireWire target disk mode.
    If your MacBook has a DVD reader and you have a Mac OS X Installer/Utilities DVD, such as the one that shipped with it, you can boot from that DVD, answer only the "what Language" question, and wait a quarter minute for the MenuBar to be drawn. Then examine the Utilities menu or the Installer menu and Find Disk Utility.

    You will have to put your phone into recovery mode and restore the phone as new. Since you don't have a back up, you will lose all the data on your phone but you will be able to use it again.

    MY iPhone 5C suddenly stopped working. It wont connect to my Mac and repeatedly reboots from the apple Logo when plugged into the wall.
    There is no water damage or anything. I got that checked at the Apple store. I also have Apple Care + but didnt let them give me a new one yet because I have photos on this that I have no yet backed up that are very important. They are the last photos I have with my grandfather. Can anyone help me. Please!

    If the phone shows the "connect to iTunes" screen, the data on the phone is most likely lost.
    Connecting in recovery mode is your only chance to use the phone again, besides getting it serviced by Apple.
