CatalinT Posted October 11, 2013 Report Share Posted October 11, 2013 Hi rstc120 I may not be the expert in this forum , but from my experience with electronic devices, specially computerized , this may be like a big doo doo. Internally meaning, Unless it does not respond to testmode, then i believe u have a dead unit. Mainboard, a shortcut somewhere, a fuse or something like that. It sounds like it does receive power since u can hear the fan. But that it. If Power words, often if the mainboard the next to look at. Hope somebody else has a better opinion on this. But to me that's what it sounds like. I hope for you , I am very wrong Quote Link to post Share on other sites
