Sense hat red led not working


#1

Hi Iast week I bought a sense hat from Pimoroni and today I was playing with smiley faces when I realised that the red LED 6th row, 7th column is not working. I replaced with green and shows fine. I guess it is a hardware problem, how can I replace my sense hat?

This is my code

from sense_hat import SenseHat

sense = SenseHat()

w = [255,255,255]
r = [255,0,0]
g = [0,255,0]
happy = [w,w,w,w,w,w,w,w,
w,w,w,w,w,w,w,w,
w,w,r,w,w,r,w,w,
w,w,w,w,w,w,w,w,
w,w,w,w,w,w,w,w,
w,r,w,w,w,w,r,w,
w,w,r,r,r,r,w,w,
w,w,w,w,w,w,w,w]

sense.set_pixels(happy)

Here I attach oe pictures which is the output of the above code where one LED is black, instead of red. I have another picture where I replaced the damaged LED with the green colour and it is bright as normal. However I am not allowed to post two pictures.

Thank you,
George.

Definitely looks like a dead pixel. If you email support@pimoroni.com then they should be able to get to the bottom of it, and send out a replacement if necessary.
