The stand, attached at the back of the screen, has snapped and needs replacing. Can it be replaced and where can I get one. the screen is fine.

Try contacting Sharp. Places that sell them may have one laying around but I doubt it.

If you can't get one, check the middle of back of the monitor for 4 screw holes (empty) in the shape of a square, they're for attaching to a wall or desk mount.

An example of a desk mount:

Please make sure that the cables are all securely plugged into the back of the monitor, and into the back of the computer. Also make sure that there is nothing that was recently placed near your monitor (or your monitor's cables) that can cause interference.

If this does not fix your problem, try connecting your monitor onto another computer to see if it works there. If it still does not work, even when connected to another computer, it is possible that your monitor cable is faulty, or the monitor itself is faulty. I recommend taking your monitor and it's cables to a computer repair shop for further repairs.
If it works on another computer, but not yours, then it is possible that your graphics card or computer may be the cause of the problem. Open the side panel of the computer and make sure your graphics card is securely plugged into it's slot. If this does not fix the problem, I recommend taking your computer in to a computer repair shop for further repairs.

Sometimes the screen goes blank and today when I restarted the computer the screen is flickering very lightly.Does this means its going?


The picture board on your monitor is bad, since the power led or button is on and all connection are corrrect, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care

Lcd monitor will not stay on

First thing to try, is to check the cable from Monitor To PC Or Graphics Card.
If you have a loose-broken internal wire, this will be the problem. Dry-Solder Joint et,c.

If the cable, has a socket either end, from monitor to computer.

try to obtain a replacement cable. The second option is to test the output source. i.e Graphics card or output to the monitor.

Hope this helps Mike @ Compurepair.

Sharp ll-t17a4-b backlight

when ever i try to sign in the messanger says erorr code 80072efd how can i solve this matter


Back light

I would suggest Tritronics for the service manual and the replacement parts. Unless you have a service manual, it takes a lot of disassembly by careful observation (or trial and error) to determine how that delicate LCD panel is put together! Of course I'd want to be sure that the problem is not in the inverter instead since that's a much more common cause of backlight trouble. Unless you happen to know it's one or more CCFLs, then of course you'd want to replace them all since they have the same aging.

Sharp LL T17A4-B (Black) 17 in.

Are you using the digital connection?? If so try using both the analog and digital connection then set the digital as the Main monitor in your graphics card interface. To check if the backlight is out, darken the room, and light a flash light into the screen. If you can see a picture, then you need to replace the backlight. Good luck
