Equipment field guide
TV and projector setup, inputs, and recovery
Checked guidance for Samsung and LG inputs, HDR modes, remotes, Wi-Fi, audio, eARC, and image-care decisions.
Start with the system
Identify before you change.
Record the exact display model, model year, region, firmware, source device, selected physical input, and the first visible symptom. Prove whether the fault affects one input, one app, or the whole display before resetting it.
- 01Exact model, year, region, firmware, and panel or projector type
- 02Source device, selected input, cable path, and enabled signal mode
- 03Remote type, power, infrared output, pairing, and physical TV controls
- 04Home network, app scope, hotspot result, and first failed network stage
- 05Audio output, ARC or eARC port, received format, and connected sound system
Ownership paths
Choose the job in front of you.
Each path states its model scope, diagnostic order, stop conditions, and the official material used to build it.
Set it up
How should it start?
Enable Input Signal Plus on the right Samsung TV port
Turn on the enhanced HDMI mode only for the connected 4K or HDR source, then verify the source output and model-specific port limits.
TVs & ProjectorsUse HDMI Ultra HD Deep Color on an LG TV
Enable the enhanced mode for a compatible 4K source and disable it when an older device becomes unstable.
Fix it
Why is it failing?
Fix a Samsung TV that will not connect to Wi-Fi
Separate a TV problem from router, internet, password, signal, and saved-network faults before resetting the television.
TVs & ProjectorsDiagnose a Samsung TV remote that does not work
Separate battery or charging failure, infrared output, Smart Remote pairing, the television itself, and universal-control problems.
TVs & ProjectorsFix an LG TV that will not connect to Wi-Fi
Use another device and a phone hotspot to distinguish router, internet, signal, password, and television network failures.
TVs & ProjectorsDiagnose an LG TV that has picture but no sound
Separate mute, source-device volume, Sound Out selection, HDMI path, and TV speaker hardware with LG’s Sound Self-Diagnosis.
TVs & ProjectorsFix Samsung TV eARC audio before resetting anything
Prove the labeled HDMI return port, Samsung sound output, digital format, and source path in an order that preserves the working evidence.
Care for it
How does it last?
Common failure pattern
Avoid the shortcut that hides evidence.
- Changing every picture setting before proving the selected input and source format
- Factory-resetting the display while the router, cable, or external source is failing
- Treating a paired Bluetooth remote and an infrared remote as the same test path
- Assuming a TV app result proves an external HDMI or audio-return path
