Step-by-Step Repair
- Step 1 of 61
Restart everything
Turn off your tv, your router (or the device it connects to), and wait 30 seconds. Turn the router on first, wait for it to fully boot (about 2 minutes), then turn on your device.

Forget and re-pair
Go to your device's connection settings. Remove/forget the connection, then set it up again from scratch. This clears corrupted pairing data.

Check for interference
Move the device closer to the router or paired device. Remove potential sources of interference — other electronics, thick walls, metal objects, and microwave ovens can all disrupt wireless signals.

Update firmware and software
Check for updates on both your device and router/paired device. Connectivity bugs are commonly fixed in firmware updates.

Reset network settings
If available, reset the network settings on your device. This clears all saved networks and connections, giving you a fresh start. You'll need to reconnect to all your networks afterward.

Factory reset as last resort
If nothing else works, a factory reset will restore the device to default settings. Back up any important data first. This fixes software corruption that simpler resets can't.

If That Didn't Work
- Try a power cycle: unplug the TV, hold the power button on the TV itself for 30 seconds, wait 2 minutes, then plug back in.
- Check all HDMI cables and try different ports.
- Update the TV firmware through the settings menu if available.
When to Call a Professional
If basic troubleshooting doesn't work, the issue may be a faulty power supply board or T-con board. Board replacement costs $100-$300 in parts, and repair labor adds another $100-$200. Given that a new 55-inch TV costs $300-$500, it often makes more sense to replace than repair.
