Monitor Failure while Software Update 3 Flashes - 09/16/09 05:14 PM
I have a Power MAC G-4 with a Apple display 21" ? About 6 years old in great condition well, I use to use this daily untill about a year ago I got a Gateway Notebook, and that took over so my MAC only got used a few times a month,I got rusty. So yesterday I got a new Nano and wanted to use it with my MAC I started it up ran Disk Utility all OK. when my Software Update poped up I started it and it installed the new Itunes then when it started the JAVA app. my screen went blank and the thing shut down. I re-started and my Monitor is blank I only get the 3 light flashes on the monitor. So checkin my manual is says my display is detecting input in the wrong video format. Check compatible with graphics card and check software installed correct.?? That is foriegn to me I know where my g-card is but why that? So I tried to reset my PRAM by the Command option P and R keys and I get nothing after the two chimes. Can anyone help??? The old MAC FixIt site use to have an answer years ago, I believe I heard about the 3 light flash before but to long ago.. Thanks....
