You can't really grab the image from the TV.. the TV only has inputs, no outputs. An external media player would work.

Nein, mit 5V explodiert dein Haus.

Also mal ehrlich. Ich hab dir eben gesagt, die Dinger brauchen 5V. Du gibst ihnen zu wenig Spannung, und wunderst dich, dass was nicht richtig geht, und fragst mich dann auch noch, ob ich in meiner Kristallkugel sehe, ob das Problem dadurch behoben wird?

Warum 4.8V? Die Dinger laufen auf 5V.

Those DC jacks have a pretty high resistance. It's better to directly solder if possible. It IS perfectly safe to connect the Pi and LEDs to the same power source.

There's no way to get the signal from the TV itself without massive cost and effort (and hacking into the TV hardware itself).

Not even remotely. The USB Port can output something around 500mAh (that's 0.5A), the Pi alone needs 1.5-2A to even start up and run properly, the LED strip will need between 10 and 18A.
Also, the 5V traces on the pi board can only handle an amp or two at best, so they'd literally go up in smoke if you tried to power anything bigger through them.

Du hast eine Spannung von 5V dann, ja. Was genau ist, was die LEDs benötigen.
Wenn das aber vorher auf 5.9V stand, dann wird es die alten LEDs gegrillt haben, fast 20% Überspannung überstehen die wenigsten Bauteile.

Ja. Wie schon mehrfach gesagt. Masse oder Datenleitung um Betrieb rumstöpseln sended willkürlichen Müll an die LEDs, das hat absolut NULL Aussagekraft.
Wenn dein 3er Teststreifen klappte und in der gleichen Konfiguration die Streifen am TV nicht klappen, sind eben die Streifen an der Glotze gegrillt worden.

Das ist Masse, ohne Masse kein Strom. Unkontrolliert kann eigentlich nur heißen, dass was mit den Signalkabeln nicht stimmt (vertauscht o.ä.) oder die Controller in den LEDs zerschossen sind.

Well, right now, hyperion is configured to only grab internally, so you wouldn't get any reaction from the external grabber. Disable the internal grabber and activate external and see if that makes any difference.

Alternatively, you can use an arduino nano/uno with FastLED.

#include <FastLED.h>


// How many leds in your strip?
#define NUM_LEDS 1


// For led chips like Neopixels, which have a data line, ground, and power, you just
// need to define DATA_PIN.  For led chipsets that are SPI based (four wires - data, clock,
// ground, and power), like the LPD8806 define both DATA_PIN and CLOCK_PIN
#define DATA_PIN 3
#define CLOCK_PIN 13


// Define the array of leds
CRGB leds[NUM_LEDS];


void setup() {
      // Uncomment/edit one of the following lines for your leds arrangement.
      // FastLED.addLeds<TM1803, DATA_PIN, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<TM1804, DATA_PIN, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<TM1809, DATA_PIN, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<WS2811, DATA_PIN, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<WS2812, DATA_PIN, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<WS2812B, DATA_PIN, RGB>(leds, NUM_LEDS);
        //FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);
      // FastLED.addLeds<APA104, DATA_PIN, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<UCS1903, DATA_PIN, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<UCS1903B, DATA_PIN, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<GW6205, DATA_PIN, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<GW6205_400, DATA_PIN, RGB>(leds, NUM_LEDS);

      // FastLED.addLeds<WS2801, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<SM16716, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<LPD8806, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<P9813, RGB>(leds, NUM_LEDS);
       FastLED.addLeds<APA102, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<DOTSTAR, RGB>(leds, NUM_LEDS);


      // FastLED.addLeds<WS2801, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<SM16716, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<LPD8806, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<P9813, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<APA102, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);
      // FastLED.addLeds<DOTSTAR, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);
}


void loop() {
  // Turn the LED on, then pause
  leds[0] = CRGB::Red;
  FastLED.show();
  delay(500);
  // Now turn the LED off, then pause
  leds[0] = CRGB::Black;
  FastLED.show();
  delay(500);
}

This would flash the LED strip red on and off, with just an arduino nano, completely independant of the PI.. that would verify that the strip itself is working right.

They're not. The GPIO hasn't changed from what I can see (it'd make the Pi 3 incompatible with a lot of hardware).

The HL-340 is the arduino.
The Arkmicro grabber is likely simply not supported, which explains the error message.

Not without actually seeing said config file and SOME information about what hardware you are even running.

You may need to use a level shifter on the data pin.

Since TVs only accept inputs, and don't have outputs, you'd need to actually hack into the hardware of the TV and identify and grab the signal on the way internally somewhere, which may involve soldering to 0.1mm chipset pins, if you can get to it at all.. and then it'll likely not be a plain video signal, but something that needs to be converted again, AND it will be vastly different between different TV models.. so, simply put, not worth it.

The number of LEDs doesn't matter until it actually shows something. But yeah, arduino wants the real LED count, so 100 LEDs = 100 in Arduino.
Are you sure the arduino is detected as ttyUSB0?
Going by the hyperion log, there's still some sort of issue witht he video grabber. What exact model is it? Run "lsusb" and post the output here please.

Hypercon sometimes won't upload the config properly, check if /etc/hyperion contains the current hyperion.conf.json.
If not, upload it manually using winscp, for example.

Also, it doesn't seem to detect your capture device properly.

Do you get the initial LED flash when you power it up? The LEDs should play some sort of color sequence if the arduino is working, and rainbow swirl sequence after if hyperion is working.

It's working out of the box, you just need to configure your config file to match your setup (LED type, number, connection type, etc).
The config ist in the default hyperion folder, root -> etc/hyperion/hyperion.config.json

Sorry, what I meant was not to use OSMC, since there's no point to using a full blown media player if you just need the Hyperion functionality.
i.e. grab this image:
[MEDIA=googledrive]1P5EYPAGexLDlyfdXKSOLKifzUr00K35c[/MEDIA]

And use that on the Pi. That's a basic linux with just the needed stuff for Hyperion.
