Trouble Shooting VU TV Problems

Plug - If the TV is not powering on and no status LEDs are lighting up, start by plugging the TV into a different outlet. If the TV is too challenging to move, you can run an extension cord from another nearby outlet.

Circuit breaker - Check the circuit breaker for the power outlet that the TV plugs into. You can check the breakers by opening the door to your breaker panel and looking for circuit breakers that are in the OFF position.

Power cable - Check the power cable. If it is a removable cable, you can test it by substituting a power cable from another piece of equipment in your home, or you can buy a replacement cable for this test.

If the TV powers on but there is no sound,

Be sure that the volume is up on input devices such as a DVD player or cable box.

Change the channel to be sure it is not just a problem with that channel.

Plug headphones into the headphone jack. If sound comes from the headphones plugged into the headphone jack, this indicates a problem with the TV speakers.

Make sure your audio cables are correctly attached. See if a new cable works.

There are many reasons that a TV may power on but have no picture.

Backlighting burned out - In modern LCD TVs, the backlighting may be burned out. A technician can replace LEDs or CCFL backlighting strips.

Inverter is bad - It is possible that the inverter, which powers the backlights, has gone bad and needs to be replaced. It’s also possible that one or more capacitors on the inverter have gone bad, in which case a technician may be able to replace capacitors more cheaply than replacing the entire inverter.

Lamp burnout - In a projection TV or older LCD TV, no picture may be caused by lamp burnout. In this case, a technician can replace the bulb quickly and easily.

Picture Is Not Displaying Correctly If the picture is displaying but there are problems such as vertical lines, a double picture, or a white display, this could indicate a faulty motherboard or mainboard.

• Try pointing the remote at all corners of the TV and see if one works/works better.
• Move objects away from the front of the TV (soundbar). The receiver for the remote is often right underneath the center of the TV, so you need to aim at that.
• Move the cable/satellite box further from the TV to avoid interference.
• Re-pair the remote with the TV (if possible).
• Replace the batteries in the remote.
• Contact manufacturer support.

Restart your smart TV and Wi-Fi router

A restart will refresh the settings on your smart TV without erasing any of your data.

Just unplug your smart TV, wait 30 seconds, then plug it back in. To restart your Wi-Fi router, unplug it, wait 30 seconds, then plug it back in too.

Check your Wi-Fi password Make sure you're using the right password and that you've entered it correctly.

If you're still using a default password—it's typically printed on a label on the bottom of your router.
