1. Make sure that the remote control is properly paired with the TV. Refer to the TV's user manual for instructions on how to pair the remote if necessary.
2. Check the batteries in the remote control and make sure they are properly inserted. If the batteries are low or not inserted correctly, the remote may not function properly.
3. Point the remote control directly at the TV's remote sensor, which is usually located at the front or bottom of the TV. Make sure there are no obstacles between the remote and the sensor.
4. Press the power button on the remote control. If the TV does not turn on, try pressing the power button multiple times.
5. If the TV still does not turn on, try unplugging the TV from the power outlet and then plugging it back in. This can help reset the TV and resolve any power issues.
6. If the flashing red light persists and the TV does not turn on, there may be an underlying problem with the TV's power supply or circuitry. In this case, it is recommended to contact Sony customer support or a qualified technician for further assistance.
