Response to Sometimes it is a bad resistor normally one of the legs on the resistors will be broken so I would visually inspect your resistor. If you do replace the resistor you have to solder it on so it is a little bit more of a professional repair. We also find that in most cases when soldering a new resistor the repair will last 1-2 years and then any future repairs last shorter, so eventually a new board will be required.
