Have audio but I have no screen. I've been hearing a clicking noise for the last few days, now it doesn't display a screen at all. What could be the problem?

What burning software/version are you using?

sound like worn universal joint bearings.

Your display adapter is the component of your computer that allows your monitor to work. On the operating system side of things, this display adapter is controlled by a device driver. If you're having issues with your display adapter (like colors are displaying incorrectly or the screen is flickering), you can fix these problems by rolling back your device driver using the Windows Device Manager.

Open your Control Panel by clicking "Start" and then "Control Panel." Click "System." Click "Device Manager." Scroll down to the "Display Adapter" heading. On a single monitor setup, there will only be one device listed under "Display" adapter. Right-click it and click "Properties." Click the "Driver" tab. Click the "Roll Back Driver" button. This will uninstall your current display adapter driver and reinstall the last version that worked properly. This will fix the issues you were having with the device. Hope this helps

Try holding in the function key (very bottom left key labeled Fn) and pressing F7. If that doesn't turn the screen back on, hold it again and slowly press F8 a few times. That should turn the screen back on if it was accidentally set to a different monitor, which seems to happen randomly on laptops.
If you can see a very faint image when its held at just the right angle, then you probably burned out the back-light.
Keep in mind, if you bought it in the last year, it is still under manufacturer warranty.

I am sorry to say the you do need to call for service, to many variables to put here. LG, the manufacturer, has several things that would have to be checked from compressor start device to main board. quicker and cheaper in the long run to call.

POSSIBILITY HERE IS THAT THE FUEL PUMP IS ACTING UP. THE REASON IS BECAUSE WITH THE WARMER TEMPERATURES THE PUMP HAS TO WORK MORE AND THIS WILL CAUSE IT TO MALFUNCTION

A clicking noise is most likely hard drive related. Does your clicking noise sound like this?

You may need a new start capacitor or fan motor.I would have the capacitor checked by a electrician and changed if needed. Good luck and thank you.

This is called and Echo, if you can get Realtek drivers or if already installed you will need to configure them not to produce this echo or at least minimize it. Click on the Speaker icon on the lower right hand of your monitor this will allow you to configure your Realtek HD Audio software. Click on sound manager ......on the Menu's click on the Microphone and select Noise Suppression this will do the magic.
