Hello
Replacing dead solidoodle2 electronics with ramps 1.4 and mega2560.
Arduino compiled and uploaded Marlin successfully but lcd display is only backlit.
Board "connected" with Repetier-host but no manual control of printer.
Any ideas where to start?.
Thanks

It sounds like you don't have the LCD Panel configured in the Configuration.h file. The LCD stuff is towards the bottom of the file.

So looking at the display section of configuration.h, when I do find the correct display/adapter do I just delete the "//"?

The display is LCD12864 which I don't see in configure.h
Is the SSD1306 OLED compatable? "#define U8GLIB_SSD1306" is very similar to recommended driver.

If its a standard LCD display just uncomment
#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

#If defined statements will setup the required files

It is a standard LCD with push/rotary input and SD card.

Pretty sure part of my trouble is the library.
The vendor supplied a compressed file U8glib.rar and I can't seem to grasp what to do with it.

All responses appreciated.

Just to make sure, have you already seen text on the display or is it the first time you power it up.
Because if it is, there is a little pot meter on the back of the display and you have to rotate it to change the contrast of the letters.
The first time if tried my lcd i couldn't see any text. But when I changed the pot value a bit I could read the text.

This is probably not the problem, but just to be sure :p

Thanks for the input. It was the zipped format of U8glib.rar library file (and location) that hung me up.
Some configuration troubles still, as for the new brain "It's Alive!"
