- An 8-slot gap between messages
With this method, up to 48 unique codes can be generated and communicated through the LED. Each code can be stored in an unsigned 16-bit integer, which can be efficiently shifted out using a simple function for error signaling (Arduino Forum).
| Type of Sequence | Slots |
|---|---|
| On Slots | 4 |
| Off Slots | 4 |
| Gap Between Messages | 8 |
Utilizing multidimensional arrays can optimize the storage and retrieval of various message patterns. Different messages can be stored at different indexes within the array, allowing for cohesive and consistent error reporting.
Additionally, Morse code can be employed for human-readable error codes. Morse code uses four symbols:
- “Dit” (·) – single-length “mark”
- “Dah” (–) – triple-length “mark”
- Single-length space – separates marks in a character
- Triple-length space – separates different characters (Arduino Forum)
By understanding and utilizing these optimum parameters and coding techniques, TV users can better interpret error messages conveyed by a blinking red light, improving their ability to troubleshoot and resolve issues with their Samsung TV.

Advanced Techniques for Blinking Light Messages
Advanced techniques for interpreting and troubleshooting the blinking red light on Samsung TVs often involve more intricate methods such as employing multidimensional arrays for varied messages and utilizing Morse code for symbol meanings.
Multidimensional Arrays for Varied Messages
One efficient method for storing and interpreting multiple blinking light messages is through the use of multidimensional arrays. This technique allows for the storage of various blink patterns at different indexes, optimizing memory usage and simplifying the process of error signaling through a single function (Arduino Forum).
Example Array Structure:
blink_codes[3][5] = {
{1, 0, 1, 1, 0}, // Error Code 1
{0, 1, 0, 1, 1}, // Error Code 2
{1, 1, 0, 0, 1} // Error Code 3
};
In the example above:
- The first sub-array
{1, 0, 1, 1, 0}could represent one specific error message. - The second
{0, 1, 0, 1, 1}might correspond to another error. - The third
{1, 1, 0, 0, 1}different error altogether.
Using this structure, the TV can relay different error messages by accessing the corresponding index in the array.
Morse Code Usage and Symbol Meanings
Morse code, also known as International Morse Code, is another sophisticated method for signaling errors using blinking lights. Morse code uses four primary symbols:
- A single-length “mark” called “dit”
- A triple-length “mark” called “dah”
- A single-length “space” separating marks within a character
- A triple-length “space” separating different characters (Arduino Forum).
Example of Morse Code Symbols in Error Blinks:
| Symbol | Representation | Blink Pattern |
|---|---|---|
| Dit | Single-Length | Short Blink |
| Dah | Triple-Length | Long Blink |
| Space | Single-Length | Short Pause |
| Gap | Triple-Length | Long Pause |
Sample Morse Code Message:
Sis represented by...(Short Blink Short Blink Short Blink)Ois represented by---(Long Blink Long Blink Long Blink)Sagain by...(Short Blink Short Blink Short Blink)
In a scenario where the TV’s red light blinks an SOS signal:
- Short Blink, Short Blink, Short Blink
- Long Blink, Long Blink, Long Blink
- Short Blink, Short Blink, Short Blink
This can indicate a specific error requiring immediate attention, and users can decode the signal using standard Morse code charts.
Using these advanced techniques, TV owners can better understand and troubleshoot issues denoted by the blinking red light on their Samsung TV. For more information on related issues, explore our resources on samsung tv red blinking light or samsung half screen dark.
