We might be able to help out more if we are better informed. Hope this helps, Daniel Chartier

Hello amar; Blinking of all LEDs on the CPU is a very bad sign, it means that CPU is defective. There could also be a MMC card problem. See the links in the following discussion for more information: https://www.automation.siemens.com/WW/forum/guests/PostShow.aspx?PageIndex=1&PostID=374612&Language=en&onlyInternet=False#top Hope this helps, Daniel Chartier
