Question:

Why is my TV in standby mode and won't wake up? What are the possible causes and solutions?

Answer:

There are three common causes for your TV staying in standby mode:

Computer in standby state: Ensure your computer is turned on and not in a standby state by checking its power light. Restart the computer if necessary.

No video signal from computer: Check whether your TV displays the message "Check Signal Cable" after disconnecting the VGA cable. This may indicate that the computer isn't sending a signal through the VGA cable.

Defective VGA cable: If replacing the VGA cable with a known working one doesn't resolve the issue, contact your computer's manufacturer or video card manufacturer for assistance.

Steps to diagnose the issue:

Verify computer status: Check if your computer is in a standby state (blinking power light). Power down and restart the computer if needed.

Disconnect VGA cable: Remove the VGA cable from either the TV or computer and see if the "Check Signal Cable" message appears. If so, try a different VGA cable.

Contact manufacturers: If the problem persists after trying a new VGA cable, reach out to your computer's manufacturer or video card manufacturer for further help.
