Inverter compatibility iMac 2308

Hi!

Two iMac EMC 2308 have come into my hands. One of them does not turn on, and another has broken LVDS connector at motherboard

I bought a new LVDS connector to replace the broken one (it has been really complicated to weld with non-professional equipment) and also noticed that inverter board was broken (missing pins for flex inverter cable)

So, I took apart inverter board from the one that does not power on and noticed they are physically identical despite the fact that the reference number is different: one is V267-707HF while the other one is V267-702HF.

I suppose they are compatible, but it takes me to a problem: iMac now boots fine, has image at external monitor but iMac screens remains black with light. All four leds at motherboard are up and internal screens is recognized by OS X. I’m not an expert on repairs so it is very likely problem is on LVDS conector but.. may the image problem be related to inverter instead of video connector?

Any help will be very much appreciated

When it is booted up, if you can discern the desktop while holding a flashlight at an angle to the screen but the screen is dark, that’s an inverter issue.

Sadly your LVDS connector and/or the circuitry near it still has issues. If you can take a second image showing more of the area around the connector we might see a missing or damaged component otherwise its the connector will need some attention.

If you had seen a faint image then that would have been the

Hi Dan

I know that this soldering is not my best job, sadly my sight is not as it used to be. I have another picture during process

Maybe some day I will feel brave enough to replace connector and try again
