9.1.4 CRT Failure
<ERROR DESCRIPTION >
THE Monitor (VGA CRT) is not displaying anything during and after System initialization.
<CHECK ITEM>
1. depress any key on the keypad to ensure that the screen saver is not active.
2. verify that the CRT power on switch is in the ON position.
3. Verify that the CRT, input power, and Main Unit VGA output connections are correct.
4. ensure that there are no active PLC inputs during the Power On Self-Test which could
interfere with normal System initialization, and result in no display.
5. Power up the System. If the problem still exists, replace the CRT with a compatible CRT
that is known to be functional. CAUTION: Prior to applying power, verify that the input
power specifications for the replacement CRT are compatible with the input power from
the System.
6. ensure that the ISA Main Unit is not located near any strong electrical or magnetic fields.
7. Confirm that the ISA Main Unit input power remains constantly within specifications:
200~230 VAC +/- 10%, 50/60 Hz, single phase.
8. Verify that the ISA Main Unit power cable is free from damage and is properly connected.
9. If the problem persists, replace the entire ISA Main Unit. (Refer to Section 8.3.1)
