I have an HP Pavilion f1503 LCD flat screen monitor----just a few weeks over a year old ...so no warranty. A month ago the monitor started going blank after it was on for about 5-8 mins. I turned it off and back on and the same page was still there so I could continue to work a bit longer until it would go blank again. I tried to go through HP help guide- found on my computer - to do a system check which all came out that it was fine. So we used the monitor for a few more week without incident until it started again this past week...only now I had approx. 1 sec. to view the screen before it would go blank again. So I couldn't run anything diagnostic on it....I decided to unplug it and try a different monitor to make sure the monitor was the issue and the old one worked fine. After plugging this one back in it stays on for 5-10 mins. and then goes blank. Any clue of what the problem is or if it is an easy/inexpensive fix? I am not a computer whiz as I am sure you have figured out by my inability to explain the problem with technical terms.....would love to hear any and all thoughts on this. THANKS!
