I may have forgotten my password for my TV...

All I can remember is its 4 letters long, and only involves letters.

Knowing that I might forget, I hid a clue on the TV remote.

Can you help me figure out my password?

Hint:

The arrows correspond to the numbers, but think about it!

Hint 2:

The line under the numbers is important

• do you mean 'numbers'? not 'letters'... – Ben May 9 '16 at 20:08
• What?! No '0' key??! :) – KeyboardWielder May 9 '16 at 20:42
• @Ben no it's letters – Beastly Gerbil May 10 '16 at 7:10

is it:

AGFD

Reasoning:

The pad has arrows, like a usual remote, however the four arrows are relocated out of position (clockwise rotation). If we do the same with the keypad we get the following:
143
852
769
Then we can use the line at the bottom to sum the three rows, as it looks like long addition. This gives 1764. If we take A=1, and so on, the answer gives AGFD

• Just try not to forget your password again! – LiamH May 10 '16 at 16:44
• :P I just realized, I just posted my password online! :) – Beastly Gerbil May 10 '16 at 17:52
• Remotes usually have up, down, left, and right arrows. The left arrow, equivalent to number 4, has moved round to the top, this is equivalent to the number 2 position. Next, the the up arrow, has moved clockwise, into the right arrow position. I hope this makes sense :) – LiamH May 11 '16 at 8:14

Reading by arrows in Calculator spelling is B(6)E(3)l(1)L(7)

• Nice idea but no – Beastly Gerbil May 10 '16 at 7:11

...if you don't LOOK! ('1' as an association to lowercase 'L' + 'O' which the arrows are forming + "OK")

• Sorry no, more complex than that – Beastly Gerbil May 10 '16 at 7:10

TFES - First letter of the number corresponding to the arrow.

Or

If the arrow actually points the Number then OSNT (One, Seven, Nine, Three)

Is it

AGCI

Because

1->A, 7->G, 3->C, 9->I
