HP G7 no signal but works.

[quic307]

Hi,

So I have an HP G7-2272 (MB - DA0R53MB6E1 revE). I hear the nb works fine but I dont have signal (display - HDMI - VGA). I change the southbr (218-0755097) but same issue. I have and another G6 with the same board but with UMA, so I have the same problem.

Does anyone seems the problem to fix it?

I attached the shematic.

Thanks.
