Symptom

The upper part of the video image bows or distorts.

Video image and audio sound suddenly go out.

Remote control unit does not work.

Probable cause

While computer system signal is input, isn’t a sync signal for composite sync (CS) or G on sync being input?

Isn’t signal with much jitter or skew distortion being input to a video deck?

Is the source setting correctly selected? Is a wrong source (forced mode) selected?

Are video picture and audio turned off by pressing the AV MUTING button on the remote control unit?

Are batteries installed correctly?

Are batteries exhausted?

Is there a shielding object between the remote control unit and the remote sensor?

Is the distance too long?

Corrective action

Input separate sync signals for vertical sync (V) and horizontal sync (H) signals.

Input signals with little jitter or distor- tion.

Set the source setting to AUTO. If the problem still persists, set it to the correct dedicated source (forced mode).

Turn on video picture and audio by pressing the remote control’s AV MUTING.

Match the polarities of batteries correctly (+ to + and - to -).

Replace with new batteries.

Remove any shielding objects.

Use the remote control unit at a nearer point.

*This projector is equipped with a microcomputer that may operate abnormally due to interference from external components. If this happens, turn off the main power and disconnect the power cord from the wall AC outlet. Then reconnect the power cord to AC outlet and turn on the main power again.

(For the turning on and off the power, see pages 27 to 28.)

Maintenance

Stains on the cabinet

Should be wiped off with a soft cloth. If the cabinet is heavily stained, wipe it with a cloth soaked in water-diluted neutral detergent and wrung well, then wipe clean with a dry cloth.

Since the cabinet may deteriorate in quality, become damaged or get its paint peeled off, be careful about the following:

Do not wipe it with a hard cloth.

Do not wipe it forcefully.

Do not wipe it with thinner or benzene.

Do not apply any volatile substance such as insecticides to it.

Do not allow any rubber or vinyl article to remain in contact with it for a long time.

Stains on the lens

Should be cleaned off with commercially available blowers or lens cleaning paper (for cleaning glasses and cameras). Do not use liquid cleaning agents. This could cause the surface coating to be removed.

Do not rub or hit the lens as its surface is prone to damage.
