In this post, we’ll provide a complete overview of LG error code 105 including what it means, common causes, and actionable troubleshooting solutions to get your LG TV back up and running. Read on to find out how to decipher and resolve error 105 on LG TV models.

What Does LG TV Error Code 105 Mean?

LG TV error code 105 indicates an issue with the set-top box or cable/satellite box connected to the TV via HDMI.

Specifically, error 105 on an LG TV points to the TV not being able to detect the input signal from the external set-top box properly. This typically occurs if there are connectivity problems with the HDMI cable, issues with the external box itself, or incorrect setup of the device.

So when LG TV error 105 pops up, it means there is some kind of communication breakdown between the TV and the set-top box via the HDMI connection. The good news is this error is typically easy to diagnose and resolve with a few simple troubleshooting tweaks covered below.

What Causes LG TV Error Code 105?

There are several potential causes that could produce error code 105 on your LG TV:

– Faulty/Loose HDMI cable – If the HDMI cable connecting your set-top box is loose or faulty, it can prevent proper signal transmission to the TV.

– Input setting issues – If the correct input source is not selected on the TV matching the HDMI connection, error 105 can occur.

– External device problems – Technical problems with the connected set-top box like software bugs, hardware faults or device malfunctions can also trigger this error.

– Incorrect resolution settings – Error 105 may appear if unsupported or incompatible display resolutions are set on the external set-top box.

While that list covers the most common causes, error 105 can also stem from things like TV software bugs or compatibility issues in some cases.

How to Troubleshoot and Fix LG TV Error Code 105

If your LG TV starts showing error code 105, don’t panic. In most instances, you can get things working again on your own without needing professional repair help. Follow these troubleshooting tips:

Check TV input settings
Navigate to the input source menu on your LG TV and confirm the correct input is selected to match the HDMI port your set-top box is connected through. The name on port assignments can sometimes be unclear (e.g. HDMI 1), so ensure it corresponds properly with the device.

Try a different HDMI port
If you have other devices connected to your TV’s HDMI ports, try moving the set-top box to a different HDMI slot. This will help rule out issues with that specific port. Just be sure to choose the corresponding input once moved.

Inspect HDMI cable connections
Check that the HDMI video cable connecting your LG TV to the set-top box is inserted securely in the ports on both devices. Also inspect the cable for any bent pins, fraying or other damage. If the cable connections are loose or the cable is faulty, replace it with a new high-speed HDMI cable.

Power cycle devices
Turn off your TV and external set-top box device, disconnect them from power, wait 60 seconds, then plug them both back in and power them on again. Power cycling forces a full reboot which can solve software glitches causing error 105.

Reset set-top box
Consult your set-top box user manual for model-specific steps to factory reset or reboot the device itself. Performing a hardware reset on the external box can help clear up any underlying issues triggering the 105 code.

Check for LG TV firmware update
In your TV settings menu, go to the General → About This TV → CHECK FOR UPDATE section to check if firmware updates are available. Keeping your LG TV software up-to-date helps prevent bugs that can cause error 105 issues.

Call LG customer support
If you still see LG TV error 105 after trying all of the steps above, your last resort is to contact LG Support with details about your troubleshooting. An agent can provide specialized support tailored to your specific TV model and help resolve persistent 105 code causes.
