About 2 years ago I bought a 17 inch Dell flatscreen (1704FPT). Roughly a year after I bought it it started turning off randomly -- the light would still be on and the computer would still treat it as being connected properly but the screen would go black like it was turned off. If I turned it off and on again I'd get a picture back for a few seconds and then it'd turn off again. It was a pretty random thing that started happening with more and more frequency until I called Dell Support and they swapped it for a new monitor without even trying to troubleshoot (Which I was quite impressed by).
It's now a year after that and the new monitor they swapped it with is starting to do the same thing. In the meantime I've bought a new computer, so it's a different computer AND monitor from the one that was having trouble before, though it's the same model monitor. However, this time it's out of warranty and Dell won't help me without $$.
What sounds like the problem? Is it something fixable or would I be better off getting a new screen? Did I just have bad luck or is that model of monitor known to be faulty in this way?
Thanks in advance for any insights anyone has!
