I got edu08 from another person and it seems that there is a same issue as in other threads. Back-lite is turning on in a few seconds after power connected but nothing is on LCD. When i am turning it off - i see a horizontal line sometime for a few seconds. Here is my voltage (board is powered from 4AAA batteries, ~5v):
connector top row:
Test point: 1.63v
One of the problem that i dont know if it was ever working. I also see that in 5m its switching off, what makes me thinking that pic controller is working and problem is somewhere in LCD circuit. I also tried to resolder connector and LCD pins, no luck so far. No shorts was found. Any help is appreciated.
