Video Not Displaying, ThinkCentre M 8120

So, my cpu was working fine until the montor went blank, and mouse/keyboard would not bring the screen back up.

 

Note: I did confirm monitor works properly in other computers.

 

I turned off CPU and disconnected all cords.

 

I recieved NO Beep.

 

Then 2 short 1 LOOOOOOOOOOOOG (never ending) beep.

 

Note; I check power, and everything is perfect. Cpu work, just does not boot on screen.

 

According to your troubleshooting I need to take the following action:

 

  1. System board
  2. LCD assembly
  3. DIMM

However, I am not sure what they mean. One advice was to reseat LCD, however, I don't know where the video card is located.

 

Please help.

 

Thanks

Re: Video Not Displaying, ThinkCentre M 8120

hey whitney,

 

Do refer to the following Hardware Maintenance Manual :

 

http://download.lenovo.com/ibmdl/pub/pc/pccbbs/thinkcentre_pdf/39j8120.pdf

 

 

 

For 1 - it refers to you checking if there is any loose components

For 2 - it refers to the monitor and for you to check that all cable is connected correctly

For 3 - it refers to the RAM of your motherboardm whereby you should remove and then resit the memory.
