Just make sure you include your order number so we know who it’s from. Ideally stick it on a printed sheet of paper with a link to this forum thread and mark it up “FAO: Phil Howard” so it comes my way pronto! We’ve not put any points into the Bureaucracy skill tree yet! ---

Just received your Display-o-Tron HAT and tested it immediately. The backlight clearly shows up some quite serious cracks in the LCD itself- I’d wager it survived testing, but obviously didn’t survive the journey to you. In short, it’s toast! We’ll get a new one sent out to you ASAP and I’ll find out what the score is for refunding your postage. ---

Looks like your SPI isn’t enabled for some reason. Try: `sudo raspi-config` Then Advanced Options -\> SPI -\> Yes & Yes ---

I am having the same problem, I am using a raspberry Pi 3 and a DOTHat. I have run all the example scripts and none are displaying any text, I have turned on SPI, tried setting the contrast turning the display on and off with lcd.set\_display\_mode and can get nothing to be displayed. Any ideas? ---

Make absolutely sure you’re running the Display-o-Tron HAT examples ([https://github.com/pimoroni/displayotron/tree/master/examples/dothat](https://github.com/pimoroni/displayotron/tree/master/examples/dothat)) and not the Display-o-Tron 3000 ones since the latter wont work. Additionally, make sure you’ve not got any code running in the background which might be interfering with the GPIO pins ( it happens). ---

Definitely running the dot hat examples, have tried the 3k ones on the off chance they would work. I installed it on a fresh installation of rasbian, first thing I did was run the install script and try to run the hello world script. I have a colleague who has one and some code working. I’m going to get him to try and see if it works on his pi. ---

That’s a good plan, let me know what you find. In the mean time I’ll see if I recall any other common gotchas it could be. There’s always the chance of a faulty board, but it’s usually something software! ---

Hi, I purchased my Display-O-Tron HAT back in November 2017 and I have only just got around to trying it out with a Raspberry Pi 3b. Unfortunately it does not display any text. All the other functions work as expected. I have looked through all the threads on the subject and haven’t found anything that helps. Are they any suggestions? - Thanks.
