Rohaan, we may be able to help you. I think you mean that ONLY the "E" (lower left rising) segment is lit. However, You will have to give a bit more information, like what decoder are you using , what info are you feeding the decoder and if at all possible a circuit diagram of what you have so far.
Connect 5 Volts dc via the correct value series resisitor to keep the segment current below 20 mA to the CA terminal(s) of the display.
Then touch the individual segment pins with a jumper to negative.
As you test you identify the pins and each segment should lit up.
Also some 7 segment displays may require a jumper to drive 2 CA terminals off the display.
And are you sure it is a CA and not a CC display ?
