sony vaio image problems

[highpulse]

well got this sony vaio with the board model MBX-217 rev1.0
this machine was turning on but no image.
cheked all coils for cores , all seems to be ok , so i gave just a bit of air on the gpu , with the hot air and it started to give image , reballed the gpu (client dont want to swap gpu) well it worked fine , so i assembled the machine tryed to turn on _!_ dam bloody vaio and they attitude .
disassembled the machine , and always that a lift a bit the board gives image !! i taught well could be a bad grounding issue or something making contact with the board once is on te chassi , but no tryed everything , always that alift a bit the board like making a presure on the board it gives good consume about 1.30 amp and start giving image , if i dont make pressure on board i got 0.17 amp turned ok , but no image .
for what i know many people have this issues with the sony board , if anyone have taught let me know .
btw also the place were usually i make pressure on the board and start working ok , is near the SB , so i also lifted and reballed SB and the same shit
any help will be welcome
