LED TV screen goes white from time to time


You might want to make sure the HDMI cable is fully plugged at both ends of the cable and try a new HDMI cable. A marginal cable will occasionally drop out the picture.

How do I turn off the subtitle / closed captioning on a Samsung series 6 6300?


Is the captioning coming from a source such as a Sky box? If so, you need to switch off closed captions on the source box and not the TV.

Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

You have set up your tv in store (demo) mode. Go to settings then plug and play and scan channels again but this time select home mode before it searches for channels.
