2.8" TFT screen displaying lines

Post by pbo »

Hi Adafruit Support,

Just received the PiTFT Mini Kit 2.8" TFT and assembled it, however I'm getting some strange lines on the screen that do not disappear. Could this be defective and if so, may i have a replacement sent, please?

Also, is there a better way of affixing the display to the board? The adhesive on the back of the display doesn't seem to hold very well.

Thanks!

Those lines are very strange. They don't look like a hardware defect. Have you gone through any of the driver installation in the tutorial?
Double-stick foam tape should hold the display. I'm surprised that the tape the display ships with is not holding. Did you fully remove the protective backing?

Hi, thanks for the reply. Im pretty sure it's a hardware defect as I am using the screen and card/image as part of the cupcade kit and didn't need to install the drivers. I ordered and built an extra TFT for the cupcade and it's working perfectly with that pi and cupcade card but when I swap the screen out for testing with the screen in question the lines appear.

The tape that is shipping with the screens are very thin adhesive that do not have foam and seem to come off very easily. Are they supposed to come with foam backed tape? Yes I did remove the backing first.

Appreciate your assistance. Thank you.
