Meldrew So you think it might be worth having a look inside
remove just the top cover and with a torch have a look at the display connector, use a chopstick to press it down to just check it’s seated. Can often be jogged loose in Transit. If that doesn’t help, trace the ribbon to the black box in the electronics bay…remove the side panel open brain box cover and check it’s seated properly in there.
If that doesn’t work put up a video unlisted on YT and link to it here, so we can see what you’re doing and so can Paolo, helps with any language barriers. Let Paolo know by e-mail. and link to your post.
You can get the link by clicking on the text to the right of your name saying when you posted, and that will bring up the link with the exact address of your post.
P.S. I’m hoping just a loose connector, as they must have checked it in the factory.
