Got 2 Mini 1.3inch 240x240
One is working and second one is not working
Attached the picture which shows working and not working unit. Both were added to same RaspBerry PI Zero W unit (obvious after shutdown)
Thanks and Regards

Re: Mini TFT 240x240
Does anything show up in an I2C scan?

Re: Mini TFT 240x240
This minTFT 240X240 is spi based right any case out of i2cdetect
pi@BDLThirucherai:/var/www/html $ sudo i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f

pi@BDLThirucherai:/var/www/html $
pi@BDLThirucherai:~ $ sudo python3 blinka.py
Hello blinka!

Re: Mini TFT 240x240
Thanks for the photo. There's a chance maybe the ribbon cable is not fully inserted? Worth trying at least. Do this unpowered. Push the little black retainer tabs (arrow) out to release, then push the ribbon cable in snuggly, and then push the retainer tabs back in.
You can use your other TFT for comparison. The product photo also appears much more inserted:
