It's definitely not the grounding.
BTW, I am currently running it in dumb mode. I have disconnected both the small connectors as mentioned in the how-to thread.
It works perfectly with the Leaf's schedule timer programming mode, but I really miss the screen.
The other observation is this: With the plastic covers off, I am able to see a bit more, the LEDs surrounding the LCD display seems to flicker and respond. This clue tells me that the LCD module is fine. The "backlight" is present on screen, so the only other thing I could try is:
1. Swap out the SD card with a working one. Maybe the SD card is corrupted and can't boot(?)
2. Swap out the computer board module with a replacement from a junked Blink.
Does anyone have any better suggestions??? Thanks!
