It only stays on standby, red LED is on but does not turn on | Changing the 3.3 volt SMD regulator, when measured it was only 3 volts and tsound was 3.3 on another 2 regulators that could not have any voltage with the device on standby, changing the regulator close to the processor and resolved. | xande | |
