We have two pcs of OLED128, one of which the display can't show clear image after power on it (see attached pic). The other can't display any image.
We can hardly find out any reason for this shortage. Can you check for us and we hope your any suggestion ...

The first questions should be are you sure you have a strong 5V going to the screen? Are you pulling the TX line high? Which object are you using to drive the screen?
I recently purchased my first oLED screens, I didn't get it to work with the first object I downloaded. I ended up with "uOLED-128-GMD1" and haven't had any problems since.

April, 2008: when I discovered the answers to all my micro-computational-botherations!
Some of my objects:
MCP3X0X ADC Driver - Programmable Schmitt inputs, frequency reading, and more!
Simple Propeller-based Database - Making life easier and more readable for all your EEPROM storage needs.
String Manipulation Library - Don't allow strings to be the bane of the Propeller, bend them to your will!
Fast Inter-Propeller Comm - Fast communication between two propellers (1.37MB/s @100MHz)!
I suggest you try asking on the support forum at 4dsystems.com.au. Others may have seen something similar. Also I believe the circuit schematic is available in the documentation - this might help you trace through the voltage levels and see what is wrong.
If all else fails - there is a new 128x128 module which has an excellent LCD screen, and these are just $29.
