Motherboard Debug Card Found Faulty

 

 

 

 

 

 

 

Three year back I ordered one Motherboard PCI Diagnosis card because I am having few bad OLD generation motherboards with me for repair.

For testing I connected this card on one of my non-working motherboard,

on triggering power this diagnosis card showing “00 00” code & I found in seven segment led display one led is not light up.

I removed card for further inspection, very few parts are installed on front side & on back side there is no components.

But when I turned back to solder side of the PCB….

I found many pins of seven segment LED Display are dry soldered.

Cleaned PCB using IPA.

Connected back on Motherboard for testing.

Now problem is resolved.
