From Flicker to Fix: The Unplugging Trick That Revived My TV


Additionally, after leaving the TV unplugged for an extended period, which allowed me to inspect its internals, the TV has been functioning without interruption for two hours. Could this improvement be attributed to the capacitors discharging or the device cooling down? I’m uncertain, but I am grateful for any assistance provided.”


When it comes to troubleshooting electronic devices like televisions, two factors often come into play: capacitor discharge and cooling down. In the case of your LG TV, which experienced issues after an attempt to overclock the refresh rate, these two factors could very well explain why the TV started functioning normally after being unplugged for a while.

Capacitors in electronic devices store electrical energy, and when a device is powered off, these capacitors gradually release their stored energy. If there was an electrical charge buildup due to overclocking, leaving the TV unplugged would allow the capacitors to discharge fully. This process can reset the electrical state of the TV’s components, potentially resolving any glitches or instabilities caused by the overclocking.

Cooling Down

Overclocking can generate excess heat, and if not managed properly, this can lead to overheating, which may cause the device to malfunction. By turning off and unplugging the TV, you allowed it to cool down. Heat dissipation could have helped in stabilizing the internal components, which might have been stressed due to the increased temperature from overclocking.


In summary, the improvement in your TV’s performance after being unplugged could be due to the capacitors discharging and the device cooling down. These actions can often rectify temporary issues caused by overclocking. However, if problems persist, it might indicate a more serious issue, and consulting a professional technician or the manufacturer’s customer service may be advisable.

Remember, while it’s tempting to push the limits of our devices, it’s crucial to do so within the manufacturer’s recommended specifications to avoid potential damage. Your experience serves as a valuable reminder of the delicate balance between seeking enhanced performance and maintaining the longevity of our electronics.
