Adjusting Antenna Positioning
Poor antenna positioning can lead to weak signal strength, resulting in missing channels or pixelated images. Adjusting the antenna’s orientation and placement can significantly improve reception.
| Positioning Tips | Details |
|---|---|
| Elevation | Place the antenna as high as possible to avoid obstructions. |
| Direction | Aim the antenna in the direction of the broadcast towers. |
| Indoor vs Outdoor | Consider using an outdoor antenna for better reception. |
Common symptoms indicating poor antenna positioning include a complete absence of channels, inaccessible specific channels, and poor signal quality leading to pixelated or freezing images (Tech Junctions).
Upgrading Antenna Quality
Upgrading to a higher-quality antenna can offer better signal reception and resolve persistent channel issues. Weak signal strength, outdated channel lists, or connection issues can contribute to channels not working.
| Antenna Types | Average Reception Range |
|---|---|
| Basic Indoor Antenna | Up to 20 miles |
| Amplified Indoor Antenna | Up to 50 miles |
| Outdoor Antenna | Up to 100 miles |
Consider these factors when choosing a new antenna:
- Reception Range: Select an antenna that matches the distance of the broadcast towers.
- Signal Strength: Opt for antennas with signal boosters to enhance reception.
- Build Quality: Higher-quality materials typically provide better durability and reliability.
Performing a channel scan, checking antenna/cable connections, and updating the TV’s firmware are initial steps to troubleshoot the issue (Tech Junctions). For further guidance on improving TV reception, explore enable hisense tv game mode and hisense tv firmware update made easy.
Resolving “Function Not Available” Message
Encountering a “Function Not Available” message on a Hisense TV can be confusing. This guide provides clear steps to address and resolve this issue.
Stuck Button Issue
Sometimes, a “Function Not Available” message is triggered by a stuck button on the remote or the TV set itself (JustAnswer). Press and release each button on both the TV and remote to ensure they are not jammed.
| Problem Area | Action |
|---|---|
| Remote Buttons | Press and release each button |
| TV Buttons | Press and release each button |
Input Setting Related Causes
This message may appear if the input settings do not align with the function being attempted. For example, trying to change channels while on an HDMI input could trigger this error (JustAnswer). Check the TV’s input settings and ensure that the correct input source is selected for the desired function.
| Input Source | Function Attempted | Message Display |
|---|---|---|
| HDMI | Channel Up/Down | “Function Not Available” |
| AV | Channel Up/Down | “Function Not Available” |
Main Board or Controls Troubleshooting
In cases where the buttons are not stuck and the issue persists, the problem may lie with the TV’s main board or control system (JustAnswer). One recommended troubleshooting step is to disconnect the control button plug from the main board after turning the TV on. This can help identify if the main board or control buttons are causing the issue.
| Step | Action |
|---|---|
| 1 | Turn the TV on |
| 2 | Remove the back cover of the TV |
| 3 | Disconnect the control button plug from the main board |
| 4 | Observe if the message disappears |

Addressing Specific Remote Related Problems
Infrared vs. Radio Frequency Remotes
Remote controls typically use either infrared (IR) or radio frequency (RF) technology to communicate with a television. Infrared remotes send signals via light pulses that require a clear line of sight to function correctly. On the other hand, RF remotes use radio waves that can pass through obstacles such as walls or furniture.
When addressing remote-related problems for Hisense TV:
-
Infrared Remotes: These require a direct line of sight with the TV’s sensor. Physical obstructions such as walls, furniture, or even high placements can prevent the infrared signals from reaching the TV. For more on troubleshooting IR remotes, explore our guide on how to pair Hisense TV remote.
-
Radio Frequency Remotes: These do not need a direct line of sight and can work through obstructions. This is less common in TV remotes but can be found in other devices.
Refer to the following table for the comparison of IR and RF remotes:
| Feature | Infrared (IR) Remote | Radio Frequency (RF) Remote |
|---|---|---|
| Line of Sight Requirement | Yes | No |
| Signal Interference from Obstacles | High | Low |
| Common Usage for TVs | Yes | Rare |
Drawer Interference with Infrared Signals
Infrared remotes can experience significant signal interference from physical barriers. Even placing the remote in a drawer can prevent it from operating correctly. According to JustAnswer, infrared signals cannot pass through solid objects, which is why storing remotes in closed compartments can lead to control issues.
To mitigate drawer interference:
- Ensure Clear Line of Sight: Always keep the remote in a position where there is an unobstructed path to the TV.
- Avoid Closed Storage: Do not store the remote in drawers or shelves that block the infrared path.

Remote Battery Signal Interference
Remote batteries can sometimes cause signal interference even when the remote is not in use. In one case documented by JustAnswer, a remote stored in a drawer was inadvertently sending signals to the TV, leading to malfunction.
To address battery-related signal interference:
- Remove Batteries: When storing the remote for lengthy periods, remove the batteries to prevent accidental signal transmission.
- Check for Battery Levels: Ensure batteries are not corroded and have sufficient charge, as low battery levels can cause erratic signals.

By understanding these specific remote-related problems and their solutions, users can maintain optimal TV functionality and avoid potential interruptions in their viewing experience.
Troubleshooting Display Issues on Samsung 55″ TV
Hard Reboot Procedure
A hard reboot is a simple yet effective way to address display issues on the Samsung 55″ TV. If you notice problems such as a darkened screen on one side, follow these steps:
