My monitor only shows a clear white screen and occassionally flashes black-sound still works. Any ideas?

Don't know if this will help but it's a DGM flatscreen.


Worked fine yesterday, did a normal shut down.


I've since restarted it, checked all cables and it's still not working.





Any help will be much appreciated.My monitor only shows a clear white screen and occassionally flashes black-sound still works. Any ideas?
Have you tried it on another computer or laptop, also can you access the OSD menu by using the buttons on the monitor, try disconnecting it from the computer and see if it continues doing this, if you can try another cable and restart your computer if you haven't already.
