PREPARATION OF NO DISPLAY, TROUBLESHOOTING FOR NO DISPLAY



FRIENDS TODAY I AM GOING TO TELL YOU ABOUT THE CORRECT STEPS TO BE TAKEN IN ORDER TO REPAIR THE COMPUTER IF THERE IS NO DISPLAY.  MEANS THAT WHEN YOU START THE COMPUTER, THE CPU FAN AND SMPS FAN IS RUNNING ALL LED IS ON BUT THERE IS NO DISPLAY IN THE MONITOR.

 

STEP 1 à START THE COMPUTER AFTER 30 SECONDS  PRESS NUM-LOCK KEY COUPLE OF TIMES.  IF THE NUM-LOCK LED IS GETTING ON AD OFF,  THEN THE PROBLEM IS WITH THE MONITOR.  IF THE NUM-LOCK LED IS ON OR STEADY ON OR STEADY OFF THEN THE PROBLEM IS WITH THE CPU.

 

STEP2à SUPPOSE THE PROBLEM IS WITH THE MONITOR

1)      CHECK THE AC WALL OUTLET (PLUG) AND POWER CODE WITH THE LINE TESTER OR MULTI-METER.  NOW CHECK THE POWER BUTTON IS ON AND THE BRIGHTNESS LEVEL OF THE MONITOR. 

2)       IF THERE IS NO POWER  IN THE MONITOR  THEN THE POWER PANEL MIGHT BE FAULTY.  REPAIR THE MONITOR IF THE POWER LED IS ON, EJECT THE VGA CABLE  FROM THE CPU AND MESSAGE WILL APPEAR ON THE DISPLAY.   

3)      IF IT DOES THEN THE VGA CABLE OR HDMI CABLE IS FAULTY.  REPLACE THE VGA AND HDMI CABLE.

4)      IF THERE IS NO MESSAGE ON THE DISPLAY, THEN THE MONITOR IS FAULTY.  REPAIR OR REPLACE THE MONITOR.

 

STEP 3 à SUPPOSE THE PROBLEM IS WITH CPU.  DURING TROUBLESHOOTING WITH THE CPU, IT IS RECOMMENDED TO USE A MOTHERBOARD, SPEAKER AND DEBUG CARD.  EJECT THE RAM CLEAN IT PROPERLY WITH THE RUBBER.  EJECT THE CMOS BATTERY CHECK THE VOLTAGE LEVEL.

 

CLEAR THE CMOS ATTACH THEM AGAIN AND CHECK FOR DISPLAY.  IF STILL THE DISPLAY DOES NOT COME ATTACH A GOOD RAM.  STILL THE PROBLEM CONTINUOUS AND THE MOTHERBOARD SPEAKER IS GENERATING 3 BEEP CODES THEN RAM SLOT MIGHT BE FAULTY.

 

SUPPOSE RAM SECTION IS OK THEN YOU CAN USE THE DEBUG CARD TO FIND OUT  THE PROBLEM OR ATTACH  A VGA CARD  IF DISPLAY COMES THEN THE VGA PORT OF THE MOTHERBOARD IS FAULTY AN IF THE DISPLAY DOES NOT COME THEN THE VGA CONTROLLER MIGHT BE FAULTY. IN BOTH CASES REPAIR THE MOTHERBOARD.
