iMac 27 late 2009: Blank screen after CPU upgrade, what I broke?
I have upgraded the CPU on my iMac 2009. Now the screen stays blank after powering on, but the iMac is still accessible via Screen Sharing (vnc) and remote login (ssh). I can see that the new CPU is working as expected.
I’m afraid that I broke the video connector to the LCD when I opened and lifted the LCD. Is it possible to test if the faulty part is the connector?
I considered to test the video output via Thunderbolt, but I only have an old monitor with VGA input.
Thanks in advance for any hint.

I bought a cheap Thunderbolt to VGA adapter to test; when I login via Screen Sharing, the external monitor shows a copy of the main screen. So it looks like the fault is somewhere between the connector on the logic board and the LCD panel?
Это хороший вопрос?

@tonyh2 - As I had feared the logic board connector needs to be replaced.
