17.3.1. PC Booting Failure

E0500 turning on the power supply, a ‘No Signal’ message appears on the monitor

[Cause]

 The input voltage (220V) and output voltage (5V, 12V) of the PC power supply have a

problem

 The HDD was damaged due to frequent booting error and failure

 The SBC board and CPU are defective (a beep sound occurs)

 The board operates abnormally due to an increase in the internal temperature of the PC

rack

 The back plane is defective (no beep sound)

 Defective vision board and MMI board (Defective RS232 port)

 Complex defects : Defective SBC board and back plane board, defective CPU, virus

infection, CUP temperature increase, etc.

 Unstable main power supply

 The CPU is overheated due to a defective CPU cooling fan

 The monitor is defective or the signal cable is not connected

[How to Check]

 Check whether the cooling fan on the Control rack operates properly when turning on

the power. If the fan does not operate, check whether the input voltage (220V) and

output voltage (5V, 12V) of the PC power supply are normal Check the input end

voltage (+12V) of the external power supply of the vision board.

 Check whether the HDD is properly recognized in the CMOS Setup

Check whether the priority of the HDD is 1 in the MMI SBC CMOS boot sequence.

 Perform the CMOS reset test and check whether the message ‘CMOS was set with the

default value’ is displayed on the screen

 Check whether the temperature at the site is higher than 24ºC

Cause Description Remarks

Defective part Turning on the power supply will display ‘No Signal’ on the

monitor.

Fast & Flexible Chip Shooter DECAN F2 Service Manual

 Check the status of the back plane. Check for any defective pins (check whether a bent

pin exists). Replace the SBC board and back plane board and check whether they are

booted properly

 Check whether the CMOS Setup screen is displayed.

 Check whether the RT, MMI, ZMP(Motion Control) board, back plane board, CPU,

HDD and cooling fan have a problem

 Check whether the main voltage is applied properly

 Check whether the CPU cooling fan operates properly

 Check whether the monitor power supply and signal cable are connected properly. If

not, replace the monitor and check whether the screen is displayed properly

[Measures]

 If the input and output of the PC power supply are abnormal, replace it.

 Replace and recover the HDD and then reinstall the MMI.

 Replace the SBC board.

 Remove the dummy slot cover and discharge the heat inside the PC rack and then

reboot the PC.place the SBC board and CPU.

 Replace the RT board and Back plane board.

 Replace the HDD or MMI board and perform HDD recovery.

 For items with a problem, refer to the above measures and apply grease between the

CPU and CPU cooling fan. (The CPU temperature is reduced by approximately 20ºC.)

 When the input power supply is unstable, propose the UPS installation.

 Replace the CPU cooling fan.

 Connect the power supply cable connected to the monitor and the signal cable again. f

the same problem occurs, replace the monitor or the signal cable.

E0501 Blue screen occurs while booting or running the PC

[Cause]

 HDD and Windows system file were damaged

 The Windows system file was infected by a virus

Booting speed becomes slower or booting failure occurs frequently.

 Defective SBC board

 Defective SBC board and HDD

 Defective SBC board and CPU

 Defective vision board and COM-VM sub-board

 The SBC board is not inserted into the vision board connector properly

 The temperature inside the PC has increased or the HDD rack case contact is defective

Troubleshooting

[How to Check]

 Check the Windows error information and check whether a bad sector occurred to the

HDD

 Check for virus infection using an anti-virus program

 Replace the SBC board and check whether the PC is booted properly

 Access the CMOS Setup screen to check whether the HDD is recognized properly

 Replace the SBC board and CPU to check whether the PC is booted properly

 Replace the vision board and COM-VM sub-board and check whether they are booted

properly

 Check whether the SBC board is inserted into the vision board connector properly

 Check whether the site temperature is higher than 24? and then check whether the

HDD is recognized properly

[Measures]

 Replace and recover the HDD and then reinstall the MMI.

 Perform virus treatment and install HDD Recovery software.

 Replace the SBC board.

 Replace the SBC board and HDD, perform HDD recovery and reinstall the MMI.

 Replace the SBC board.

 Replace the vision board or COM-VM sub-board.

 Remove the SBC board and insert it into the vision board connector properly.

 Remove the slot cover and discharge the heat inside the PC rack and then reboot the

PC.

E0502 The PC stops when it almost starts Windows while booting the PC

[Cause]

 The ‘Initializing and establishing link …’ error occurred in the DOS mode

 Defective HDD

 The memory of the SBC board is not inserted properly

 Defective SBC board

[How to Check]

 Check for the occurrence of the ‘Initializing and establishing link’ error

 Access the CMOS Setup screen to check whether the HDD is recognized properly

 Check whether the memory of the SBC board is inserted properly

 Replace the SBC board and check whether the PC is booted properly
