need help to get oled to work

[doughboy]

I just got an I2C oled and tried the examples from adafruit and u8glib and nothing works.
I2C scanner reports address as 0x3C and I have adjusted those on the respective library.
Anything else I can try or did I get a defective oled (besides the misaligned screen)?

on adafruit library ssd1306_128x64_i2c example program, only random dots get displayed. The display remains blank using u8glib.


Thanks.

this always happen, I googled and googled and could not find an answer, and as soon as I post a question, I find the answer.

FWIW, here is the modified oled reset circuit as described in the above link and it now works.
need to do some smd soldering.

It's pretty incredible they'd sell these products which can't work as designed.
