Resistance Vin to Gnd approx 126 Ohms
This is an issue: the VIN to GND resistance is too low. The instructions clearly that ‘The resistance should be at least several kilo-ohms. If either resistance is below one kilo-ohm, there is probably a shorting or solder bridge somewhere.’
It’s going to be a bit tricky to find out the issue. But to start, I’d ask you to post pictures of the front and back of the PCB (without LCD), and either post them here or send to [email protected]. Take the pictures under good lighting conditions and high resolution. Thanks.
