Try checking the IC in the mother board for Display segment there might be a minor dry solder in some joints

 

[iamkamalrandhawa]

always an dry solder is not cuase of no display there are too many problem's for this. Like cpu supply, ram Supply, NB Supply, Reset and many more.

 

[jeffrey samuel]

When the Smps is fine along with the fact the display works for other combination then the data path has some internal errors in them

which chip ??

the north bridge chip and check all capacitor

Post a picture of the SMPS if the output voltages are fine then the problem may be in the tracks connection verify if there are any short circuit in it

 

[iamkamalrandhawa]

may be its smps loose jack.
