Hi guys, i am having some trouble with my X7 and i hope you can help me. I haven't used my box for more than a year and thought that it would be a proper idea to update it. I followed the instructions of this video with the X7 Kitkat 250 ( february 8th 2016 ) firmware on my Win 7 PC. When i tried it out and plugged it in (TV), it said "no signal" for a few seconds, then the screen became black. Another few seconds and again "no signal" and so on... The blue LED was shining. Last time i used the X7 everything worked fine but i've read that many people get problems whe they haven't used it for a while. Problem is, i can't remember which firmware i had, just that i've never made an update before (haven't used it a lot) Hope you've got any ideas on how to fix this.
