Having the PT-6800 Serviced

If you are unable to solve the problem, you should have the projector serviced. Pack the projector in the original car-
ton. (See “Unpacking the PT-6800” on page 1.) Include a description of the problem and a checklist of the steps you 

An incorrect date and time are displayed.

Correct the date and time using the DOS DATE and TIME 
commands or the options in the Setup Utility. (You can also 
set the date and time in Windows by double clicking the 
clock on the task bar or in the control panel.) If the date and 
time become incorrect after a short time, the CMOS battery 
may be depleted. Replace the battery.

The following message appears at boot up:

“Invalid system disk,

Replace the disk, and then press any key”

Ensure that an operating system is installed. 

Check the boot sequence in the BIOS setup utility.

You hear irregular beeps during operation of 
the computer and the system halts.

Have the PT-6800 serviced.

An unidentified message is displayed.

Reboot the computer and run the BIOS Setup Utility. Con-
firm the Setup Utility parameters. If the same message is 
displayed after booting up again, have the PT-6800 ser-
viced.

You cannot operate the printer.

Check the printer cable connection.

Ensure that the printer power switch is turned on.

Confirm that the printer is on-line.

You cannot use a mouse or keyboard.

Check the cable connection.

Check the mouse or keyboard with another computer to see 
if it works. If the same problem occurs, replace the mouse 
or keyboard.

The screen is blank and you don't hear any 
beeps.

Check that the AC adapter is connected to the PT-6800 and 
the power cord is plugged into a working electrical outlet.

Check that the power is on. (Press the power switch again 
for confirmation.)

The screen is blank and you hear a continu-
ous beep, or two or more beeps.

Have the PT-6800 serviced.

Only the cursor appears. 

Reinstall the operating system, and power on the PT-6800.

Audio problems

Ensure the audio cable is not defective. 

The mute is off.
