if you will write us partnumber of the unit or attach a unit label photo (better) it will be easier for us to give you the answer :)

RL66 is the eeprom with data you need to read.

[zdan3h]

yea rl66 93c66 right ? when i connect it shows me only 2 pins connected i dont wont to take it if the board cuz i dident do that ever before.

[credoline]

93C66 normal pinout - pin 5 GND
93C66 rotated pinout - pin 7 GND

Unsolder chip from baord and read it !!

dont worry, this is not motorola MCU with a "tons" of small pins :)
take it out and read. the GND pin can be easily found if you check the paths on the PCB.
