I have had this monitor for about 3 years. Just a few days ago, it suddenly started to go blank with a loud click, and then stay blank for 1 to 5 minutes. Then there is another click and it comes back on. During this time, nothing seems to trigger it back on, and the power LCD stays green. It's like something overheats and it clicks off, but I felt the case and nothing is hot, and no burning electrical smell. I have never had a problem with this monitor before. I have a GeForce 6800 card, and I am running Windows XP SP2. I have made sure I have the latest drivers from Nvidia.
One of the times when it was blanked out, I hooked it up to a laptop (I don't have another desktop machine handy) and shared the view, but the desktop monitor remained blank. When it clicked back to life, it displayed the laptop view as expected. Does this mean this monitor is screwed? Is there any way to be sure? A diagnostic tool?
Thanks for any advice!
