Turning a Roku TV off with the power button isn't the same as restarting it. Roku's own support guidance draws that line and describes a separate system restart. This guide shows how to restart Roku TV in the two ways Roku describes, by unplugging the TV or from the Settings menu, and what Roku says to check first.
A TV that shuts itself off, or keeps switching on and off, can have several causes. If you're asking why does my Samsung TV keep turning off, this guide goes through what Samsung's UK and US support pages say, with each step credited to the page it comes from.

LED or LCD? The two labels look like they name different kinds of TV, but they don't. If you're wondering what is an LED LCD TV, RTINGS' explainer on LED TVs gives a plain answer: an LED TV is an LCD TV that uses LEDs as a backlight. This guide walks through what that means, how the layers of the screen work, and what RTINGS says these TVs do well and less well. We haven't tested any TVs for this article; everything below comes from RTINGS.

LG sells the C6H only in 77 and 83 inches, and RTINGS describes it as a more premium version of the LG C6 OLED 2026, with a more advanced tandem OLED panel. This review draws on RTINGS' published review of the LG C6H. We haven't tested the TV ourselves, so everything below is attributed to RTINGS.
At 77 inches, Samsung's S90H line quietly splits into two different TVs depending on size — and picking the wrong one means paying mid-flagship money without getting the panel that justifies it. The 77-inch model is one of three sizes in the line built around Samsung's RGB Tandem panel, while the 55-, 65-, and 83-inch versions use a standard WOLED panel instead.

If a movie you're watching suddenly looks like it was shot on a soap-opera set instead of on film, motion smoothing is almost always the reason. Here's what the feature actually does, and how to turn it off.
TV screens are more delicate than they look, and the wrong cloth or cleaner can leave permanent damage. Here's what Samsung and LG each recommend, plus the method both agree on.
