The Video Display Does Not Appear

If the computer starts up but no image appears on the screen, follow

these steps to solve the problem:

Check to see that the power indicator on the video monitor is lit. If it

is not, turn off the monitor's power, wait 5 seconds, then turn the

power back on. Wait to see if the display screen image appears.

2. Use the controls on the monitor to turn up the brightness and con-

trast.

3. Remove any diskettes, then turn off the power switches on the moni-

tor and the main unit. Check that the monitor's power cable is

securely connected to the electrical outlet and that the monitor cable

is properly connected to both the monitor and the main unit. Turn

both power switches back on.

Turn off the power switches on both the main unit and the monitor.

Then check the electrical outlet for power. Plug a portable lamp into

the outlet you are using for the monitor and turn it on to see if the

outlet supplies power.

5. Follow the instructions in Chapter 4 to remove the cover from the

Equity III main unit and check DIP switch 1-2 to be sure it is set cor-

rectly for your monitor type. Be sure the computer is off and all cables

are disconnected from the main unit before you remove the cover.

If the computer locks up and does not respond to the keyboard, try

the following:

Wait a few seconds. Some operations take longer to perform than

others. For example, a spreadsheet program takes longer to recalculate

an entire spreadsheet than to record one figure. Also, BASIC pro-

grams that have a lot of calculations to perform can take several min-

utes, or even hours. Be aware of the task the computer is performing

and judge the time accordingly.

2. Check the key lock to see if it is locked. If it is, the computer does not

respond to anything you enter on the keyboard. Turn the key to the

vertical position to unlock it.

3. If the computer remains locked up, follow the steps in Chapter 2

under "Resetting the Computer."
