Try it on naother PC and also check the VGA/DVI cable. If it still does not work and you want to DIY repair, then please read below.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed LG and other monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My acer 5750 i7 keeps shutting down


The infected laptops encounter random shutdown problem until some maintenance activity is being performed on the system.


Two important things that you should do to fix a laptop which keeps shutting down are:


1- Scanning computer to eliminate malwares, spywares and the viruses from your laptop.


2- Repairing and cleaning Windows registry.


The registry errors, however, are the internal errors and can become a cause of system crashes and freezes.
For an instant fix use system utility tool Reginout.
