@liutas4x4 Hi No, I have no schematic but it is not normal to have a voltage regulator with output shorted to ground. Removing the resistor you are removing the shorted part of the circuit shorting...

And Yes, by all means rma it if is still under warranty. Just by trying to open it you will probably void it, and there should be no reason to open it and investigate a fault if it is still covered...

@den3d Hi, True is a word that does not apply to all cases as you know. In my case, having that specific error and a vcc line shorted to ground at that specific point in the circuit, I can assure you...

@kobig Hi Kobi, must check that again but from memory it should be R239, marked with "0". Measure resistance to ground at that point and if it is shorted then that should be the resistor. From sot23...

0R resistor next to yellow tantalum capacitor on pcb - Vcc line shorted to ground beyond this point. Removed this resistor, no more 9805 error, no short to ground, wi-fi working. This does apparently...
