Everything else works.\r\n\r\nI did a little poking around in \"Conditionals_LCD.h\", I tried changing the contrast to 35, but it did not work. I then replaced this code\r\n\r\n`    #if ENABLED(miniVIKI)`\r\n`      #define LCD_CONTRAST_MIN      75`\r\n`      #define LCD_CONTRAST_MAX     115`\r\n`      #define DEFAULT_LCD_CONTRAST  95`\r\n`      #define U8GLIB_ST7565_64128N`\r\n`    #elif ENABLED(VIKI2)`\r\n`      #define LCD_CONTRAST_MIN       0`\r\n`      #define LCD_CONTRAST_MAX     255`\r\n`      #define DEFAULT_LCD_CONTRAST 35`\r\n`      #define U8GLIB_ST7565_64128N`\r\n`    #elif ENABLED(ELB_FULL_GRAPHIC_CONTROLLER)`\r\n`      #define LCD_CONTRAST_MIN      90`\r\n`      #define LCD_CONTRAST_MAX     130`\r\n`      #define DEFAULT_LCD_CONTRAST 110`\r\n`      #define U8GLIB_LM6059_AF`\r\n`      #define SD_DETECT_INVERTED`\r\n`    #endif`\r\n\r\nwith this code from my working V1.1.4\r\n\r\n`    #if ENABLED(miniVIKI)`\r\n`      #define LCD_CONTRAST_MIN  75`\r\n`      #define LCD_CONTRAST_MAX 115`\r\n`      #define DEFAULT_LCD_CONTRAST 95`\r\n`    #elif ENABLED(VIKI2)`\r\n`      #define DEFAULT_LCD_CONTRAST 35`\r\n`    #elif ENABLED(ELB_FULL_GRAPHIC_CONTROLLER)`\r\n`      #define LCD_CONTRAST_MIN  90`\r\n`      #define LCD_CONTRAST_MAX 130`\r\n`      #define DEFAULT_LCD_CONTRAST 110`\r\n`      #define U8GLIB_LM6059_AF`\r\n`      #define SD_DETECT_INVERTED`\r\n`    #endif`\r\n\r\nand the display came to life. I am a noob when it comes to programming, I understand the basics but that is about it. I don't know why my change worked, but it did. \r\n\r\nAlso, the display is shifted to the right by 4 columns. Those 4 columns are still showing the splash screen no matter what is on the screen. On the main info screen they are there, on the menu screen they are there. I have no idea where to look to correct this issue.\r\n\r\nThanks for the help"},"comment":{"url":"https://api.github.com/repos/MarlinFirmware/Marlin/issues/comments/366583270","html_url":"https://github.com/MarlinFirmware/Marlin/issues/9459#issuecomment-366583270","issue_url":"https://api.github.com/repos/MarlinFirmware/Marlin/issues/9459","id":366583270,"user":{"login":"Bob-the-Kuhn","id":20692583,"avatar_url":"https://avatars0.githubusercontent.com/u/20692583?v=4","gravatar_id":"","url":"https://api.github.com/users/Bob-the-Kuhn","html_url":"https://github.com/Bob-the-Kuhn","followers_url":"https://api.github.com/users/Bob-the-Kuhn/followers","following_url":"https://api.github.com/users/Bob-the-Kuhn/following{/other_user}","gists_url":"https://api.github.com/users/Bob-the-Kuhn/gists{/gist_id}","starred_url":"https://api.github.com/users/Bob-the-Kuhn/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Bob-the-Kuhn/subscriptions","organizations_url":"https://api.github.com/users/Bob-the-Kuhn/orgs","repos_url":"https://api.github.com/users/Bob-the-Kuhn/repos","events_url":"https://api.github.com/users/Bob-the-Kuhn/events{/privacy}","received_events_url":"https://api.github.com/users/Bob-the-Kuhn/received_events","type":"User","site_admin":false},"created_at":"2018-02-19T03:55:09Z","updated_at":"2018-02-19T03:55:09Z","author_association":"CONTRIBUTOR","body":"I changed the low nibble to 0x04 in both places & that shifted my entire display left by four pixels.
