Westinghouse Tv Input Source Problem

Having problems getting your Westinghouse TV to detect the right input source and display video? Don’t panic – we’ve got you covered. This detailed guide walks through all the common causes and proven solutions to fix Westinghouse TV input and no signal issues.

Common Causes of Westinghouse TV Input Problems

Before jumping into the step-by-step troubleshooting process, it helps to understand what usually causes input source problems on Westinghouse TVs in the first place:

  • Faulty or Loose HDMI Cables: Damaged, old cables or loose connections are the most common culprit. Reseating cables often helps.
  • Incorrect Input Source Selection: Choosing the wrong input mode on your TV for the device that’s connected.
  • Outdated Firmware: Bugs in outdated TV software can prevent input recognition.
  • Device Connectivity Issues: Problems with the external streaming box, DVD player or other source device itself.
  • Bad Ports: Defective HDMI ports on older Westinghouse TVs can fail to transmit signal.

Understanding the root cause will give you a systematic way to isolate and fix the issue. Now let’s walk through the troubleshooting steps.

Step-by-Step Guide to Fix Westinghouse TV Input Problems

Follow this process to methodically diagnose and resolve any input detection issues with your Westinghouse television:

1. Check Input Source Settings

The first thing to check – make sure your Westinghouse TV input source is set to the correct port for the device you want to display.

  • Press “Input” or “Source” on your remote and select the matching port that it’s connected to.
  • If you have multiple devices hooked up, cycle through each input.

This simple reselection of the input mode resolves many no signal issues.

2. Try Different HDMI Cables and Ports

Faulty or degraded HDMI cables cause a huge percentage of input problems:

  • Replace old HDMI cables with brand new ones that support 4K video.
  • Try connecting devices to different HDMI ports on your TV.
  • Firmly reseat all cable connections at both ends.

Many times, simply reseating cables or using different ports resolves input detection issues after upgrading AV equipment.

3. Power Cycle All Devices

Here’s a simple step that shockingly fixes many modern HDMI handshake issues:

  • Unplug TV power from electrical outlet for 60 seconds.
  • Shut down any streaming boxes, Blu-ray players and game consoles.
  • Plug TV power back in and restart external devices.

Allow a few minutes for the TV input to re-handshake with sources. This often resolves glitchy software connectivity issues.

4. Factory Reset the Westinghouse TV

If you still see no signal on your Westinghouse television, a factory reset usually clears any software gremlins. See our guide on how to reset a Westinghouse TV without a remote for steps.

  • Select “Reset” from the TV settings menu. This returns software to default.
  • Retune TV channels and reconfigure settings after restart.

Factory resetting TVs fixes all kinds of weird HDMI bugs – so don’t skip this step.

After factory resetting, you’ll need to reconfigure channel favorites, Wi-Fi passwords, and troubleshoot things like no sound from the speakers.

5. Update Westinghouse TV Firmware

Another culprit is outdated firmware causing compatibility issues with newer 4K video sources.

  • Check Westinghouse support site for latest firmware update files.
  • Download update to USB stick, insert into TV USB port.
  • Allow firmware installation, cycling power when prompted.

Updating to current Westinghouse TV firmware boosts input connectivity.

6. Isolate Source Device Failure

If you’ve tried different cables, ports, and firmware – it’s time to troubleshoot the external source. Connect your streaming box, Blu-ray player or game console that’s having input issues to another TV:

  • If the device works fine on other TVs, the issue lies with your Westinghouse television.
  • However if it STILL doesn’t work on other TVs, the external source device itself has failed.

This isolation test helps identify whether the root cause is the Westinghouse TV or the media devices hooked up to it. Replace faulty gear.

7. Try a HDMI Signal Amplifier

For older Westinghouse TVs with finicky HDMI boards, signal amplification can help:

  • HDMI amplifiers boost and extend signals from injury-prone ports.
  • Position amplifiers between media devices and faulty TV ports.
  • Test if amplification enables input detection from glitchy sources.

While not ideal, HDMI amplifiers are an inexpensive way to revive dodgy connections.

When All Else Fails, Replace Main Boards

If you’ve systematically tried everything else in this troubleshooting guide with no luck getting video signal – the issue likely lies with your Westinghouse TV’s main board itself.

While replacing main boards is more costly, it ultimately resolves input issues due to aging HDMI electronics.

Key Takeaways on Fixing Westinghouse TV Input Problems

To recap, follow this structured troubleshooting approach when dealing with no signal or input issues on your Westinghouse television:

  • Verify input source settings match your connected devices.
  • Replace faulty HDMI cables and shuffle connections.
  • Power cycle all equipment to reset software handshakes.
  • Factory reset the Westinghouse TV to clear bugs.
  • Update firmware to resolve compatibility problems.
  • Isolate issues between TV and external media sources.
  • Try HDMI signal amplifiers for dodgy ports.
  • Replace the main board if all else fails.

Taking these steps methodically will resolve the vast majority of input and no signal problems on Westinghouse televisions.

Frequently Asked Questions

Q: Why does my Westinghouse TV say “No Signal”?

A: The most common causes of the “No Signal” message appearing on Westinghouse TVs are loose cable connections, incorrect input selected for your media device, outdated firmware causing compatibility issues, or faulty source equipment like a streaming box.

Q: My Westinghouse TV won’t detect HDMI input – how do I fix it?

A: Start by double checking the input mode matches the HDMI port you’re connected to. Try swapping high speed 4K HDMI cables and ports next. If issues persist, perform a factory reset on the TV and update to the latest firmware to clear any software bugs preventing input detection.

Q: I changed cable providers – now my Westinghouse TV has no signal. What should I do?

A: Start by re-running the channel scan function on your TV to sync it with your new cable services and boxes. You’ll need to reselect favorites and customizations like you did originally. Ensure all cable TV equipment is updated to the latest firmware as well. Try the troubleshooting steps above too.

Q: How do I perform a factory reset on my Westinghouse television?

A: The process varies a bit by model, but in general select the Reset option from your TV settings menu. This will return the unit to original default software condition. You’ll have to re-add Wi-Fi passwords, video inputs, channel favorites and customizations afterwards.
