full control graphic lcd Blank

Archer

I recently purchaced a full control graphic lcd and it is backlit but blank. I used the configuration tool and selected the one for the full control graphic lcd but that hasnt helped. Im using a standard ramps 1.4 board with the smart connector.

That combination is well tested and works out of the box (FEATURE_CONTROLLER 11 is the right value in configuration.h). If that is the case check cable orientation or mixing the 2 cables and if the cables are crimped correctly (have already heard about that error).

Thanks for the quick reply and sorry for the delay of my reply. the screen is on but shows no images I have tried trimming the pot but that was also no help. 

my code in the controller section is as follows: 

#ifndef SDSUPPORT  // Some boards have sd support on board. These define the values already in pins.h

#define SDSUPPORT 0

#undef SDCARDDETECT

#define SDCARDDETECT -1

#define SDCARDDETECTINVERTED 0

To clarify I get a backlight but no display and no beeps as I turn the rotary encoder

That is correct for RAMPS with RRD Full Graphic controller. If you have enough RAM (900 byte) shown on compilation result in Arduino IDE it would work.

So in that case check hardware - cables connected to right ports on RAMPS with right orientation? Do the connector cables work (test if it connects the right pins only and not neighbouring pins and most of all, all pins.).

Hello, I have the same issus, for the record all the hardware work becouse is working with marlin 1.1.0-1, but when I install the repetier firmware, no mather the version, the screen is blank with back light and after the ms that I define in the configuration the rotary encoder work becouse I ear the beeper, so I don't think that is hardware, but some miss configuration , or the arduino IDE don´t meke the correct compilatio, I don't know.
