If "frequency" was the fault, you'd have completely a dead monitor, not just part of the input stage. It's not an input stage that's concerned with video frequencies, that's a display generation issue. We're back at the original list of likely scenarios: Physical failure of the plug and socket. Technical failure of the input stage for various reasons unrelated to input frequency (such as a fault caused from the video card it was connected to, the input stage being zapped while connecting up, spurious failure). It's more than likely that it's your computer hardware that killed it, than the software that's on it. > It seems to me that too many of you are ready... Don't argue with an electronics engineer (i.e. myself) about diagnosing technical faults, unless you happen to be one, too. Likewise, don't bite off the heads of other software people on the list who might just know more than you do. I, and many others, find the customer rarely to be right about the causes and actual conditions of a fault. -- Test running FC6 & FC5, and still using FC4. I delete all private mail, unseen. I read from the list.
