S2340LC, buying new adapter?

I've had this monitor for quite a few years now, so definitely out of warranty. But is it still possible to buy a replacement power adapter as my current one keeps getting the 'Wrong power adapter detected. The display will shut down in 10 seconds' message. Was working fine previously, not sure what happened to it. Is it still possible to buy a new adapter for it? Because I can't find it anywhere. Or is it no longer manufactured? Thanks.
