Question

Your new DVD player is not working. The power turns on, but the television screen remains blank. Which reference should you use?

encyclopedia
repair manual
technical dictionary
user guide
This one seems easy but I just like to always have a second answer.

Answer 1

I believe you should use user guide because maybe such problems are listed in the guide for your DVD player. Since you probably aren't going to repair the machine on your own, there is no need for looking for the solution in the repair manual.
