We have a Gateway desk top with a flat screen monitor. The warrantee is now expired. The monitor flickers on briefly and goes black. I unplugged the monitor from the PC and attempted to do a self test. It did not work so I have to assume that the monitor is broken. Is it worth fixing a monitor? Are they "fixable". We bought the entire thing together but I would assume flat screen monitors aren't cheap. Should I take it in to be fixed knowing that they may charge me a lot of $$$ or should I consider it "disposable"?
