The TV currently turns on, plays sound and displays image but it the image is hardly visible, lower quality and quite dark.

I try to change settings on the TV like screen settings (e.g. changing brightness/contrast to see if it changes how the image looks) and no effect so I'm sure something is wrong with the TV itself but no idea what. Has anyone had a similar issue and have any idea on how to repair it?

Thank you in advance!
