Common Issues when using LG 300 TVs
LG TV Power Failure
Pay attention if your LG TV is placed near damp or water-absorbing walls, as this can affect the circuits inside the TV. Prolonged exposure may cause the LG TV to lose power.

In case of sudden high voltage, such as lightning strikes, certain components like fuses, capacitors, power supply, and ICs may get damaged, leading to power failure.

Furthermore, one of the reasons for LG TV power failure is when the TV is only turned off from the remote without unplugging the power cord. This practice, if continued, can lead to component damage due to residual electricity.

LG TV high voltage failure
There are two possible reasons for LG TV malfunction or high voltage failure:
- Electrical instability occurs due to overloaded power source or multiple devices drawing power from a single source.
The main circuit board of LG TV is malfunctioning.
Identify if your LG TV's main circuit board is faulty through the following signs:
- LG TV fails to respond to remote control commands, cannot tune channels, doesn't recognize manufacturer's original resolution, loses menu functions on screen, displays inaccurate colors, fails to receive signals, and exhibits automatic channel switching and volume adjustment.
