Q Light Controller+

Yesterday i Use THE RP and it work well. Today it startup till the end and then nothing. QLC dont startup. This is already the second time that this happens. THE first time i installed complete again.

So i power off adaptet of THE RP and THE next day there is a problem

Sorry but this is quite a poor report, as it misses all the information that can help to understand what is happening to you.

From what you write I would say your SD card is reaching its end of life.
But again:
- are you using the RPi touchscreen ?
- have you changed any of the configuration files ?
- do you have a project set as autostart ?
- if so, which plugins are you using ?
- etc....

Please, details.

The sd card is brand new and 16GB

- are you using the RPi touchscreen ?
No just a screen

- have you changed any of the configuration files ?
No not during the show and after. Only pulled the power off and the next day on
- do you have a project set as autostart ?
Yes i have, during the show i make some changing in the scenes and saved them.
- if so, which plugins are you using ?
Enttec dmx, and elation midicon

The last line of the startup i'll see and then nothing.. waiting waiting.. I have a other sd card with QLC on it as backup and this one was working fine.

Some time ago it happened to me to see lot of SD card read errors during the boot.
Sometimes QLC+ didn't start but I could clearly see the Linux kernel panicked.

I think it got fixed by flashing a bigger image on it.
Basically I suggest you to perform a low level format of the SD card. It writes zeros on all the memory and in case mark the bad sectors.

I use a sandisk 16GB HC I
So this can be the problem?

What do you mean by format at low level?
I use apple pi baker app

What is the current capacity of your power supply - suggest you up-rate your power supply, it can be the source of all sorts of spurious issues.

I have 2A power supply and use a powered hub
