Read the symptom titles below and pick the one that matches what you are actually observing rather than what you suspect is wrong. Each page opens with a short answer you can act on immediately, then works through the causes in order of how often each one turns out to be responsible. Half of them resolve without buying anything, so work top to bottom before you reach for a replacement part.
