That's a warrany issue, not a DIY issue. Contact the shop or Samsung.
Hey Guys,
I received a Samsung smart TV for Christmas about 3 months ago and it worked perfectly for a few months until now. The TV displays a deep blue light in low light (I can see this when there are few external lights on in the background) when its turned on, but I cannot see any picture. I can hear audio fine, but that's it.
Thanks in advance...
