IZ75H-2BOM Smart TV not turning on, Lavender ring around power button.

Troubleshooting Guide: Resolving Power Issues with IZ75H-2BOM Smart TV

If you’re encountering persistent startup issues with your IZ75H-2BOM Smart TV, you’re not alone. Many users and technicians have reported similar symptoms, including the appearance of a lavender ring around the power button and the device’s failure to power on reliably. This article aims to provide an overview of the problem, potential causes, and recommended troubleshooting steps to help you diagnose and resolve the issue efficiently.

Understanding the Issue

The primary concern involves the TV’s inability to turn on through usual methods such as short or long presses of the power button. In some cases, pressing the power button results in no response; in others, a lavender or purple ring appears around the power button. Occasionally, disconnecting the power supply for an extended period (more than five minutes) temporarily enables the TV to power on, often accompanied by a red indicator ring, but the problem often recurs shortly after.

Observed Symptoms

• Consistent failure to power on via normal button presses
• Presence of a lavender or purple ring around the power button
• Intermittent successful startup after unplugging and re-plugging
• Occasional red indicators during startup attempts
• Recurrent issues even after long power-offs

Potential Causes

While specific manufacturer details are scarce, the symptoms suggest several possible underlying issues:

• Firmware or Software Glitch: Firmware corruption or bugs can prevent proper boot-up.
• Hardware Faults: Faulty power supply components, such as capacitors or voltage regulators.
• Mainboard or BIOS Issues: The motherboard or embedded controller may be malfunctioning.
• Indicator Lights Signaling Errors: Color-coded LED indicators often represent specific error codes, which can help diagnose the root cause.

Troubleshooting Steps

1. Perform a Power Reset
2. Unplug the TV from the electrical outlet.
3. Wait for at least 10 minutes to ensure capacitors are fully discharged.

4. Replug and attempt to turn on the device.

5. Inspect External Factors

6. Confirm the power outlet is supplying consistent voltage.

7. Use a different power cord or outlet to rule out electrical issues.

8. Check for Indicator Codes

9. Observe the LED indicator around the power button.

10. Note the color and any blinking patterns; these may correspond to specific error codes.

11. Update Firmware (if accessible)
