Have you given up?

Can you turn on advanced logging using the debug tool and then collect the logs when the problem occurs and post? It might give a clue as to what is wrong.

Attached, thanks.

So... It's a brick?

This sucks. You shipped a defective product with no way to update the firmware. Even when it does occasionally work the software is abysmal.

Can't the service port be used to do it? I am an embedded systems developer so have the knowledge to do it and at this stage might as well give it a go.

Hi.

I've had a good look through the logs, and actually everything looks fine, this doesn't seem to be hitting any FW issues. I'm afraid you've probably been unlucky and one of the electrical components has died preventing the backlight from operating.

If you put an image with some high contrast on it (e.g. on your windows backdrop), can you see anything if you shine a bright light on it?

DisplayLink only makes the video chip - we didn't manufacture the whole product you have, so I'm afraid there's not a lot more we can do - our bit seems to be working fine

I'm sorry you've had a bad experience, but there are more exciting products on the market than the U70 now.

There is nothing on the screen, it isn't a backlight problem. It just doesn't do anything, the LED does not come on.
