Hello,

I'm having trouble getting my display to work properly and would appreciate any advice.
Here is the link to the related files:  https://oshwlab.com/red.parrot.139/0-87-oled

Here are the symptoms:
When I first powered on the display, the screen brightness was about 50% lower than expected, and there were some visible glitches in parts of the display. After that, the display stopped turning on entirely.

I'm unsure whether this is due to a simple soldering mistake or a design flaw in the circuit. I'd appreciate any insights or suggestions.

Thank you.
