KK 2.0 blank screen

Hi Folks;

I searched the forum on this and got close but could not really find an answer so here goes. I've got a brand new KK 2.0 board. The LCD screen had popped loose in shippment, the ribbon connector looks OK so I popped it back in place. When I hook up power and RX, the backlight comes on, the RX has power, but the LCD screen is blank. Is there a reset for this? Thanks for your time.

Jim

Are you sure you have the cables around the right way? Negative should be toward the edge of the board

Hi Wendo;

Affirmative on polarity. I have another KK 2.0 I have used so I've got the basics. I haven't had many responses though so maybe it's an unusual occurence. Thanks for your time.

You could try re-flashing the firmware, if it's brand new you probably want to get it up to 1.5 anyway.

Some people have reported a blank screen on power up but pressing a button usually brings the screen to life

kk boards

I had a similar problem with kk2.1hc boards, I bought 2 and both of them were u/s straight out of the box. Backlit but no words. The vendor (HobbyKing) replaced them after I had posted a video of the problem on youtube (at HobbyKing request). Sorry, but I can't offer a solution.
