If your picture drops out, takes a long time to display, or you see black bars, follow the steps below to stabilize the connection and correct the video output.

1) Confirm the device is powered on and connections are secure

• Make sure your HDMI or DVI device (cable box, game console, Blu-ray player, PC, etc.) is fully powered on.

• Reseat both ends of the cable:

  • Unplug the HDMI/DVI cable from the TV and the device

  • Plug it back in firmly

Tip: If you’re using DVI-to-HDMI, remember that DVI carries video only—audio must be connected separately (if needed) using another cable.

2) Power reset the TV and the connected device

If the video still goes in and out, appears slowly, or doesn’t appear consistently:

1. Turn off the TV and the connected device.

2. Unplug both power cords from the wall/outlet.

3. Wait 30–60 seconds.

4. Plug them back in.

5. Turn the device on first, then turn the TV on.

This can refresh the HDMI “handshake” between the device and the TV.

3) Try a different HDMI input or cable

• Move the device to a different HDMI input (example: HDMI 1 → HDMI 2).

• If available, test with a different High Speed HDMI® cable (a faulty or older cable can cause dropouts).

Tip: Avoid adapters/splitters/switches during testing—connect the device directly to the TV.

4) If the issue continues, try component (YPbPr) as an alternate connection (if available)

If your device and TV both support component video:

• Connect using the YPbPr (red/blue/green) component jacks (and the matching audio cables if required).

• This can help confirm whether the problem is specifically related to HDMI/DVI communication.

If component isn’t available or doesn’t help, contact the device manufacturer for HDMI/DVI output troubleshooting (the issue may be the device’s output settings or hardware).

5) Fix black bars on the left and right sides of the picture

If you see black bars on each side, the connected device may be outputting a resolution or aspect ratio that doesn’t match your TV.

On the connected device, look for Video Output, Display, or Resolution settings and try:

• 720p

• 1080i

Tip: Also check for an Aspect Ratio setting (such as 16:9, Wide, Screen Fit, or Full) on the device to better match your TV.

Extra tips (if you still have issues)

• If you’re using a receiver/soundbar between the device and TV, test by connecting the device directly to the TV first.

• If the problem happens with only one device, it’s likely related to that device’s cable, settings, or HDMI port. If it happens with multiple devices, it may point to the TV input/cable path.
