Question:

Why is my home theater shutting down automatically or displaying "Protection" and turning off? What can I do to prevent this issue?

Answer:

Your home theater is likely overheating, causing it to shut down automatically and display "Protection" on the front display. This is a safety feature to prevent any potential damage to the device. Overheating can occur when the home theater is placed near other electronic devices generating excessive heat or in an enclosed space that hinders proper cooling.

To reduce the likelihood of overheating and related shutdowns:

Move your home theater to a more open area, ensuring there's proper ventilation around the device.

Avoid stacking the home theater with other heat-generating electronics.

Ensure the surrounding environment isn't too hot, as this can also contribute to overheating.

If, after relocating your home theater, it continues to shut down automatically or display "PROTECTION," it may require servicing. This is true even if the home theater doesn't appear to be overheating.
