Start with simple checks like connections and force restarts; if it's a Windows problem, accessing the Recovery Environment for system restores or driver management is key.
Reset the AC adapter by leaving it unplugged from both ends for at least 30 seconds. While performing this step, verify that you are using the Nintendo Switch AC adapter (model no. HAC-002) or another compatible AC adapter and check for any cuts, kinks, frayed cables, etc.

Connectivity failures, including Wi-Fi dropouts or HDMI inputs not working, can stem from software glitches or failing boards. A TV that won't power on may be dealing with power supply issues, cord damage, or outlet failure. If your remote isn't responding, it could be as simple as dead batteries or a pairing problem.
Ensure your TV's software is current by accessing the support or update feature within your TV's settings. Inspect the Energy Saving Features: Today's TVs often come with built-in energy-saving features that can inadvertently dim your screen. Look for a setting named 'Energy Saving' or 'Power Saving' on your TV's menu.
What TVs last a long time? LED, OLED, and QLED TVs are known for their long lifespan, especially models from reputable brands like Sony, LG, Samsung, and Panasonic. LED TVs are particularly durable due to their solid-state nature, with OLED and QLED offering even better longevity.
