I had to leave my Spider kit alone for a while but now trying to get back into it by running a tutorial program with the camera and button.
The program runs ok except the LCD just stays white. I ran a simpler program to PWM an external LED and that works ok.
I don’t see or smell anything odd; the cap on back of LCD looks normal. All connectors are seated.
There aren’t many miles on this LCD so hopefully it’s not dead.
This is probably unrelated but I first noticed the LCD problem while trying to upgrade to 4.2 on a new computer which had not been used to run any programs before.
I got an error message about not being able to connect to the device so I went back to the older computer with 4.1 to make sure the Spider wasn’t dead. I confirmed the Spider was alive but the LCD remained white. I think this last paragraph is not relevant to the LCD problem but just in case.
