Default [HELP]About using [ROM][4.4.2]CM-11.0 Experimental

I am having an issue when turning on my tab plus using [ROM][4.4.2]CM-11.0 Experimental by daniel_hk. After the galaxy tab logo, it always ended up in black screen but when I tried to turn it on while charging or plugging it on my usb, it boots normally. Anyone knows a fix for that problem? I also have an issue in turning it off, everytime I turn it off it just only restarting I ended up draining the battery to totally turn it off. (sorry for my bad english)
