My double-sided tape disappears or won't stick to the TV?

1. Please pay attention when tearing off the tape: The double-sided tape must remain on the light strip instead of the protective paper.
2. Keep the mounting surface clean and dry before installing the strip light.
3. The light strip comes with 3M tape, but the brackets kits(Included) need to be used for more secure installation (Just the tape is not enough to hold it in place).
