Question about Computer Monitors
Gericom 19" tft screen mains power board not working
SOURCE: I turn on my Rosewill 19
14brad, It sure sounds like the "switch-mode-power-supply" has detected a fault with some other circuit or with itself and is going in and out of SHUTDOWN mode to try and save itself from having a nonrecovrable catastrophic failure. A tech will need to evaluate it, or he will buy it from you for $5 US. If he is lucky he will put less than $6 in parts into it and resell it for $40-$60. Go visit YOUTUBE and search and view video clips of LCD monitor disassembly and LCD monitor repair. also try ccl-la.com/badcaps.htm or www.badcaps.net and www.lcdparts.net for more info. Then you will be able to make a decision on what course of action you will want to take be it repair or trade-in for new monitor. If this was good info for you, please rate this response on fixya. 12fixlouie

Open it up and check for bad caps in the power supply first, post back what you see so we can guide you further, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums
