| + | Labeled Pin 1 on the "RF" connector actually Pin 2 on the display connector | ||
| + | |||
| + | Labeled Pin 26 on the "RF" connector actually Pin 1 on the display connector | ||
| + | |||
| + | Labeled Pin 25 on the "RF" connector actually Pin 50 on the display connector | ||
| + | |||
| + | Labeled Pin 50 on the " RF" connector actually Pin 49 on the display connector | ||
