Why did my Dell E171FP Monitor suddenly go all glitchy? Is there an inexpensive way to fix it?

I have had the monitor for several years now and one day whilst browsing the interwebs the monitor glitched and turned mostly white with buggy bits of image here and there. I checked my pc, cables, graphics card and even hooked up another monitor everything seems fine, so the problem must be in the monitor itself. Is there a way to fix this or do I need to just buy a new one?

You might just be better off buying a new monitor.
