Possible home hardware issues causing the error

In addition to the problems mentioned above, possible hardware problems in your home can cause your Sony TV to malfunction. While this is not as common, it is good to rule it out. These are the most common utility problems you might have:

• Voltage: While your outlet may be working properly, it may not deliver enough voltage for the TV to operate. When your TV is plugged in and turned on, look for a solid red light instead of a flashing one. This indicates that the Sony TV is receiving enough voltage to function properly.
• Direct power supply: Be sure to remove any smart plugs or surge switches. Instead, plug your Sony TV directly into an outlet.
