7. Fold the LCD flex cable at the crease as shown in Figure 17, so that the 
name of the LCD panel manufacturer faces up. The manufacturer is either 
Torisan (T-Sanyo) or Sharp. 
The connectors are identical on the Torisan and Sharp LCD panels, but they 
are mounted reverse with respect to each other. This means that pin 1 on 
the Torisan panel connector is at the opposite end when compared to pin 1 
on the Sharp panel connector.
The LCD flex cable can connect to either panel by making one fold to the 
cable. The words To r i s a n and Sharp are printed on the cable (see 
Figure 17). If you are installing a Torisan LCD panel, fold the cable at the 
crease so the word To r i s a n is facing up. If you are installing a Sharp LCD 
panel, fold the cable at the crease so the word Sharp is facing up.
