A Word About The Troubleshooting Charts
Troubleshooting charts cannot solve every problem!
Troubleshooting charts are a useful tool in tracing simple problems down to the board or major component level.
Follow the troubleshooting chart as far as you can until the problem is resolved or you reach a dead end.
If you find yourself coming back to the same point in the troubleshooting chart several times, call the factory and
obtain the help of a trained technician. Let him know what point you keep coming to in the chart. This will help us to
improve the troubleshooting chart in the future.
