Check Speaker Resistance - Toshiba TDP-P5 Service Manual

Check Speaker Resistance

This procedure allows you to check the speaker in the projector to see if the voice coil is functional. If the
projector lacks audio output through the speaker, you can use this procedure to determine whether the
speaker is bad or if an audio problem exists in the amplifier on the controller ECA.
Checking the Speaker
1 Remove the top case (page 9).
2 Locate the speaker terminals on the back of the speaker in the bottom case.
3 Use an ohmmeter to check the resistance between the terminals. A measurement between 7 and
8 ohms indicates a good speaker. If you read more or less resistance, the speaker is damaged.
