This applies to any type of device that has a circuit board.
The device is not working, so anything you do is a possible fix.
Best to just do this to the circuit board.
I have gotten bad motherboards working, by placing them in a oven, set on low temp setting.
Usually a bad solder joint can be the problem.
The heat helps to melt solder connection, so it is good again.
Reflow soldering is a very effective method for soldering circuit boards with lots of surface mount components.
...
Reflow Soldering1. Preheat the oven to ~ 100 degrees Celsius.
2. Insert board into the oven.
3. Raise the temperature gradually up to 220 degrees and let it stay there for 1-2 minutes.
4. Take out board and let it cool.
The max time period used is important.
Electrolytic capacitors pop at high temp.
So carefully watch the time and do not keep it in oven too long!
