Troubleshooting
[edit | edit source]The symptom charts cover geometry, synchronisation, video and miscellaneous faults. Almost every cure is "Replace monitor". The exceptions are a distorted raster and a jittering or flashing picture, where Apple's first steps are to move the display away from electrical equipment, switch off fluorescent lights, adjust brightness and contrast, and check that the ground cables are secure.[3]
