iMac Boots to Black Screen?

[sunapple]

Yesterday must've been a tough day for our 2007 iMac. It suddenly became outdated when Sierra launched and now it won't turn on anymore

Specs: iMac mid 2007 20" 2.4Ghz, 3GB RAM

Observations when pressing power button after plugging in the power cord:
- A quick bzz-bzz indicates the SuperDrive woke up
- Hard Drive starts ticking like normal
- Screen stays black
- No boot sound (maybe sound was turned of before shut-down)
- Little background fan-noise
- Wired keyboard caps-lock shows no light when clicked
- Shining a bright light does not reveal anything on the screen which indicates the LCD is fully off

Connecting an external display via Displayport > VGA adapter doesn't result in an image on the external screen.

Safe Boot, NVRAM reset, cmd + R showed no results. It never rebooted on NVRAM reset for instance.

Possible defective parts: graphics card, LCD, ...? How can I know for sure and what else can be done to try and wake up the iMac?

Luckily, thanks to iCloud, data recovery is not needed. We have a MacBook Pro and iPad to replace the iMac, but it would be such a shame if it would end like this. It was the first Mac we got and it would turn 10 years old next year. I hope it can be fixed somehow.

Much appreciated!

Either my iMac has no change of survival or my thread is being snowed under (is that just something that Dutch people say?) by the iPhone 7 threads.

Considering you are Dutch, give www.macrepair.nl a call, they can help you out.

Thanks for the reply, sorry it's so late but I missed it somehow. I guess it would be a great option if it was a bit more close by (considering the initial research is free), but the computer is so old it's not worth the long drive.

I was hoping someone recognized the problem so I'd be able to tell which part needs replacement (or it might've been a software problem). I would love for it to work again, but it can't cost to much money.

I'm considering at least getting the data from the internal drive, maybe just by getting it out and mounting externally to my own machine (not sure what I would need for that).
