Tenergy Balance Charger

[9W Monighan]

Has anybody tried one of these chargers? I just received one today to charge my battery on my Tournarocker build. I plugged it in a couple time today at work to see what it did. Now this evening I sat down to further read the instructions and when I plugged it in,the screen showed the various text and then it went to a solid lighted screen I'm not sure if it's bad or locked in some menu. I tried plugging it in again and again but no text.
Any ideas???????
