Flat screen TV with a fault (Cheadle Hulme SK8)

Samsung TV that has recently developed two continuous bright spots on the screen. Hopefully you can see them to the left of the screen in the first photo. Something small is rattling around in the case, possibly related to the bright spots?!
Approximate size: on support stand H680mm, W1080mm, D55mm
Screen size: 47” or 1200mm diagonal.
If more than one person wants this I will put the names in a draw. Please include a phone number with your request.
