my T-Display S3 does not boot anymore. When I connect a usb cable the red led on the back lights but nothing more.
On my computer no serial port shows up either.

I had a look on the back and I noticed that one component was completely burnt.
I think it's a voltage regulator (3.3volts?) but I'm not sure.

Could someone have a look on their board and let me know the type of the component so I can replace it?
I can't read the lettering since it's burnt.

Looking at the back of the board with the usb connector to the right: it's the SOT25 (SOT23-5) component in the right corner down.
It's placed between some caps left and right.

Best regards
