    there is no manafacturer logo. someone suggested a component cable. i use to occasionly get flickers of the screen on my l.c.d. the chords are fine because they work in a monitor. i am trying to link up a monitor and the l.c.d at the moment but that doesnt work either. would a component cable bypass the problem?

  • clint_wanles May 15, 2009

    also my l.c.d works fine apart from the p.c. part. maybe the p.c port was fried when my friend was fiddling aroun. so i plug it into the t.v and nothing. then the same plug goes into a monitor and the monitor works fine so the vga cables are fine

    Have you tried to restart your PC with the LCD connected to it? Some video cards will not allow you to enable a video port if you didn't start the computer with it connected.
    Can you check on the native resolution of the LCD and make sure you can change the screen resolution upon selecting the extended screen in Display Settings?

    Do you get the "no signal" message on the LCD when you turn it off and on?

    Since you said second DVI port, that must be a individual graphics card. Is there a onboard VGA port on the back of the machine near the USB connectors? If so, try connect a screen to it and boot up the PC.

    Do you see anything when the pc is first booting up? A manufacturer logo?

I think you may have the computer's graphics settings set beyond what the LCD will handle, so it refuses to respond. With the monitor connected, change the desktop settings (size and refresh) lower and see if that gets you a screen once again. You can then reconfigure the settings to maximize for the LCD.

My imate jamin wont read any sim card

Mate...same thing happen to me. I put in 3 different sim cards which all work on my other phone. So, try fiddling with the plated contact on the sim card holder (lack of other term for it). I just raised the contacts a bit, making sure there is good contact between the sim card and the leads. Works fine now. Good luck.


be careful not to raise the pin to high or the pins might snap.

How to protect my belkin 54g wireless connection from intruders. Please help me with that

There is no sure way to stop intruders - if they want to get in they can and will.

However in saying that you can certainly be smarter than the average jo driving around an estate looking for open wireless routers.

First thing first, always change the default password for the router (admin, password). If you can, change the username also (from admin to something else).

Secondly I would recommend that you enable some kind of WPA (or WEP) protection. This basically means that anyone attempting to connect to your wireless will require a "password" to connect to you. The more bits the password has the longer the password is and usally the harder it is to crack (via a brute force attack).

Thirdly - Hide your SSID. All routers by default show to the world they exist. If someone doesnt see it broadcasting generally they wont know its there.

Forthly. I would recommend setting up access lists. On every network card (be it wired or wireless) has a unique identifier called a MAC address. An access list restricts which MAC addresses can physically connect to your router. To find out your mac address click Start - Run. Type CMD. Type IPCONFIG /ALL

Fifthly - This may require a bit more fiddling around between both the router and PC's but may be worth it in the long run. Most routers broadcast whats called DHCP. This is what gives you an internal IP address. If your router allows you setup the DHCP settings to something incorrect EG: Different Subnet mask, DNS settings, Default Gateway. Then setup your home PC's manually to the correct settings. This way if someone does end up cracking your router it will throw another curveball at them as they will not be able to surf the net, view your shared files, without more fiddling.

As far as PC based security goes, I would suggest that you check any shared files or folders you may have and disable, setup how many people can use it at once, permissions etc for them. Best way to check would be Click Start - Run. Type \\ <- This will connect to your pc via the network.
