Samsung monitor 2233rs switches off after two sec...why

 

[Outlander_04]

does it behave the same way when connected to a different computer?

and what EXACTLY happens , and exactly WHEN does it happen

 

[Guilherme Ferreira]

it's probably the lcd backlight that reach the end of live.
try to exchange the lcd or buy another monitor.
a led should have more live time.
