Totally inoperative, the 5v does not reach pin 1 of the connector that goes to the main board. | Resistor r7314 | Replace r7314. in this case the resistor had replaced its value to a lower value, even though this is difficult to happen. However, sometimes the glue under the resistor that conducts and replaces its value. | Company Tronics |
