U4 Replacement on NEXTION 7 inch display.

I mistakenly connected my display to 12V and U4 burnt out.

Does anyone have the Data Sheet Specs on U4, or can send me a pic of the numbering on a working 7 inch displays U4.

Better yet know where i can download a circuit diagram.


No circuit diagram - close source.

Answer same as Pauls in Other thread.
