Have you tried starting it without any memory card inside? How are you powering it?

Have you tried powering it with a USB adapter (phone charger) in your home wall outlet?

Is this a new camera or one that you've had for a while and this is a new issue?

So with car charger, you see only a blank/black screen, but with a USB charger you see a very dark image? Very strange indeed. The only thing I can think of to try, would be to reinstall the firmware.
It's also possible the battery needs replacement. They are cheap if you are handy and can do it your self.

Would you be able to see it when using a USB charger? Thought you said it's just very dark?
Might be worth opening up the camera and looking at the battery to see if it looks OK. Possible your screen is just shot. Hard to say. If you search the Dome threads, there is a thread were someone replaced the battery on the G90C not too long ago.

Here is the thread I was thinking of. Thinking more about your issue, I'm leaning more towards a bad lcd screen. I doubt that's something worth replacing unless you already had a spare.

Your original post said you could see the start up screen, then it goes black. Are you referring to the startup screen of the red car? Does this startup screen look normal (not dark)?

That would seem to indicate that the screen is OK. So, you said when you power it inside with a USB charger (phone charger) that you can see the screen, but it's just really dark. From what you can see, when it's dark, is it the normal screen you would see if the screen was normal? Or does the screen look different? Does the camera still record normally?

So your screen lights up and you see the red car icon? Does it freeze on the car icon or just go black?
You can try to transfer the firmware to the card with a card reader. Then place the card in the camera and start it. Don’t use your computers or cars USB ports to update. Use a USB wall charger (phone charger) or supplied car charger during the update.
