Solution #2: Confirm If Your Circuit Breaker Is In Good Condition

If your Sony TV fails to turn on completely and shows no power at all, your circuit breaker may be tripped, hence no power flow.

Your circuit breaker tends to flip when there are power outages on most occasions.

The solution is to check if your circuit breaker switch is on. If it is flipped, kindly turn it on. After flipping it back, your TV should power on.

Solution #3: Check Your Power Sources

One of the issues that can cause your TV to go blank all of a sudden or fail to power on is the power source.

If power is not on your TV, the power source has an issue. It is possible that the TV cable is spoiled or the socket has malfunctioned.

So, you first need to check if the socket has power. You can remove the cable from the socket, then plug in another adapter and use it on a different device.

If it fails to allow heat to flow, then the socket is the issue.

If the socket flows power to another device, your power cable might be the problem. Try using a different cable from the power outlet to your TV and see if the issue resolves.

Method #4: Leaky Capacitor

Check also if the circuit board has burn marks, discolorations, or other signs that will show that it is not in good condition.

After checking the capacitors, you may also need to check transistors. Use a multimeter to check them for continuity.

It is possible that since these transistors are on the heatsinks, they got burnt, hence causing a poor supply of power to your TV.

The solution will be to replace any faulty device with a new one. Do it if you can, but do not hesitate to call an electrician to handle the case if you are not sure.

Method #5: Low Voltage

The solution would be to wait until the electricity gains back its strength. If it does not happen, you will need to measure the voltage available on your cables. Then, you can upgrade the wires.
