Hi all, I have 17" Dell monitor - E173FP When I switch it on, I can see my desktop. After 2 seconds or so, it turns itself off, but the green power button stays on. I pressed the power button to turn it off and back on again, I can see the desktop. Then it turns itself off. What is causing that problem? Backlight faulty? Or something else? Also is it easily fixed by myself? I don't really fancy splashing out for a new monitor if I can fix it for a few pounds! Thanks all.
