I replaced the AMS1117 and the C5 electro.
Voltage is now 3.32v, but I notice the 3.3v regulator is quite warm after it has been running for a few minutes.
Display, with the "new" TFT is still blank white. The wi-fi is connecting and time is being set from NTP
Where to now, please?
Something is not right, the regulator shouldn't get very hot.
Have you checked for any short between the 3.3V rail and GND before the installation of the new regulator?
Well, my best guess is that due to some reason IC1 becomes damaged, this IC is very sensitive to static.
If you wish, I can try to check what is happening with the board and eventually repair it (if necessary I will replace the IC1 at no cost). Just send it to me, together with the Meduino board and the TFT display. Let me know if this is good for you.
