Discount RepRap LCD controller

DBSDBS

I use Discount RepRap LCD controller.

The VERY strange thing is that this controller works when it decide.

- Sometimes it starts and all is OK, 

- sometimes after good start, the values on the display becomes unreadable (some very strange symbols); 

- sometimes the problem disappears and it returns in a normal stage; 

- sometimes it shows only two white lines; 

- sometimes "Emergency Stop" helps deciding the problem, sometimes - not

I tried with different LCD controllers, different RAMPS, with different cables, different firmwares (even with Marlin). Nothing changes.

Sound like uncomplete data transfer. If different cable do not work, check soldering of pin headers on printer board and smartcontroller.
