tv keeps restarting on its own every 10-15 minutes, stuck in a loop.

Diagnosis

This restart loop is typically caused by a software corruption from a recent update, a hardware overheating issue due to blocked ventilation, or a failing power supply. Less commonly, it can indicate a deeper hardware fault like a failing eMMC storage chip on the main board.

How to Fix It

Start with a full power cycle and cooling period.

1. Unplug the TV's power cord from the wall outlet for at least 2 minutes. This fully resets the hardware.
2. While unplugged, inspect and clear any dust from the ventilation slots on the back and sides of the TV. Ensure the TV is not in an enclosed cabinet.
3. Plug the power cord directly into a known-good wall outlet, avoiding power strips or surge protectors for this test.
4. Turn the TV on and observe. If the issue persists, proceed to a software reset: Go to Settings > System > Power and perform a System restart.

If That Didn't Work

If the restart loop continues, you need to reinstall the TV's operating software.

1. Perform a factory reset. Navigate to Settings > System > Advanced system settings > Factory reset and follow the prompts. This erases all accounts, apps, and settings.
2. If you cannot access the menu, try a hardware factory reset: With the TV unplugged, press and hold the physical reset button (if present, often a pinhole on the back) or the mute button on the TV itself. While holding it, plug the TV back in and continue holding for about 20 seconds until the reset screen appears.
3. After the reset, set up the TV minimally without logging into all your apps immediately to test stability.

Heads Up

If the TV consistently restarts during the factory reset process or immediately after, the eMMC flash memory chip on the main board has likely failed. This is a component-level repair requiring a main board replacement, which should be done by a qualified technician.
