I made a mistake and connected my Nextion 7" in 12VDC :-(
Now it does not work and the L1 heats a lot. Any tip? Is it fixable or I lost it?
Thanks in advance.
Sorry, I know everyone would like good news in times like this.
12V is too far over acceptable operating voltages.
But in the future you most likely wont forget a regulator for Nextion's power line.
Less helpful for now, ... future you will see it as more helpful then
If you are lucky, you only blew the 5V regulator. Find it and replace it with a similar one.. You have nothing to loose and it will cost you < $1 for the part...
I have changed it. It was burnt! But the display did not work. I found another IC with problem... IL6EB. I will try to by and change.
Thanks for the tip!
Hello i saw a topic where you fixed your nextion screen but i cant reply in that topic.
I could use your help and buy from you u7 and u4. hope this thread doesnt get blocked as well.
I have 8 nextion 7 screens i spent over 1000 eur on nextion products it sucks that they dont want you to fix their screens when they burn out, in mi case because of a failed power supply.
anyway if you are willing to help please let me know. tank you so much in advance.
