160x120 LCD Module Black Display

 Hi,

I use 2 of this Displays. Both Display get black with UART - Connection. They worked 2-4 hours normally,

after that with dataconnection they get black. By disconnecting and reconnecting Power, they work without 

dataconnection. By reconnect data, they would be black over the holl display. Hardwareerror?

 

Best Regards Sven

 What was the logic level on your master controller? was it RS232?

RE:160x120 LCD Module Black Display

 The display is connected with an Arduino UNO on Port 1 (TX). I can controll the Backlight.

 It's unusual. 

Can you adjust the contrast?
