well ive seen a lot of you people having this issue, it happened to me today, i did research and the mayority send it back and get a replacement after a couple of weeks.
I only saw someone say that after 2 days unplugged it magically worked. and on another forum i saw a guy that said it was a polarity issue.
Now this LCD has been working for at least a month, regular use, only by me.
Now today it wont start, just the blue led, and no response from controller or hard buttons on the lcd.
Any suggestions?
