Hi there! I understand the iStrip+ light is blinking red and you can't change its color. Let's get to the bottom of this to restore your full color control.

First, could you tell me a bit more about the situation? For example:
- When did you first notice the blinking red light?
- Is the strip physically connected properly—no loose plugs or bends?
- Have you already tried any steps like unplugging and replugging it or restarting the app?

While you respond, here’s a common step-by-step to try:

1. Unplug and Replug the LED Strip: Sometimes, a reset of the physical connection helps clear issues caused by loose wiring or temporary glitches.

2. Check the Power Supply: Make sure the power supply voltage matches the LED strip’s required voltage. Incorrect or failing power sources can cause blinking or color errors.

3. Reset the Controller or Strip: If your iStrip+ controller or app has a reset option, try resetting it to default settings to clear any stuck color modes.

4. Inspect the Wiring and Connectors: Look closely for any damaged cables or bent pins that might interfere with color signals.

5. Update or Reinstall the iStrip+ App: Ensure you have the latest version and consider reinstalling to eliminate software hiccups.

If you tried these and the light still blinks red and won’t respond to color changes, there may be a hardware fault or a more complex software issue.

Please let me know your previous attempts or observations, and we can dig deeper from there!

Are you able to check the above, or do you want me to walk you through any step?
