Hey there eurosapdafydd,
How very strange. It sounds like one of the screen lights isn’t working properly. Has the camera been dropped or anything? You can send it to us to repair for you, absolutely no problem. Its it’s in warranty, we’ll do it all for free. If it’s not, you just need to pay the associated postage costs (£5) as it’s not a big issue to fix.
Please send firstname.lastname@example.org an e-mail, and reference your forum name (eurosapdafydd) with your warranty receipt (if within 12 months) or simply to request an RMA number if it’s outside the warranty and we’ll action getting you back on track.
