Standby light is not on. TV will not turn on, either with the remote control, or the power button on the TV. Wall electrical recepticle is active.

Try following the steps below.
Step 1
Press the power button once. If the TV does not turn on, observe the LED indicator, usually located on the TV's lower front panel. If the LED indicator turned off after you pressed the power button once, it is in standby mode. Press the power button once again to exit standby and turn on the TV.

Step 2
Observe the Standby light if the remote control will not work. If the Standby light stays on, the television is in Standby mode. Press the power button on the television, then try to use the remote.

Step 3
Turn the Energy Saving Switch off, then press the power button. The Energy Saving Switch is located on the rear or side panel on most Sony model TVs. Refer to your TV user manual for the exact location of the switch.

Hi does the TV have any standby light etc, if so power off at the wall and leave for 1 minute the power back on and watch the standby LED it may or may not blink try to power on if the light blinks this may be a fault code and you can search this up with the model number.

The standby light on a Sony television indicates when the television is turned on and operating, or turned off and in "standby" mode. However, this light also serves a secondary function: indicating when there is a problem with the television by flashing. When the standby light begins to flash, there are two reset options that can be performed to resolve whatever issue it's indicating -- a power reset and a factory reset

POWER RESET
1. Turn off your TV

2. Unplug the television from the electrical outlet. If you're using a surge protector or power strip, disconnect the television from the strip itself. Only by disconnecting the power cord from the outlet can you ensure no power reaches the TV during the power cycle.

3. Leave the television without power for at least 60 seconds. This gives the television enough time for all components to power down during the power cycle

4. Plug the television back into the electrical outlet. If you're using a surge protector or power strip, plug the television directly into the wall outlet instead. The surge protector may otherwise interfere with the power-up cycle, especially if it is old or damaged.

5. Turn on the television. If the blinking standby light continues, you'll need to move on to the factory reset process.

FACTORY RESET

1. Turn on the television.

2. Press and hold either the "Reset" or up arrow button on the remote control.

3. Press and release the "Power" button on the front of the television, while keeping the "Reset" or up arrow button on the remote depressed.
4. Release the "Reset" or up arrow button.
5. Allow the television to reset after the "Reset" message appears on the screen.
6. Make no adjustments to the television for at least one minute after the reset has completed. This is to allow the television time to finish auto-configuration and initial set up.
7.Turn off the television and unplug the power cord from the electrical outlet.
8. Wait ten seconds, then plug the television back into the electrical outlet and turn on the TV.
9. Follow all on-screen instructions to complete setup. These are the instructions displayed the first time you set up the television, for configuring channels, menu language, time, display properties and more.

If you can't turn it on with the on button on the tv its not the remote causing issues. Are you able to pull the back off it and take some voltage measurement readings/

I also have an LG TV. I used this 4 digit code: 0742.

TO PROGRAM THE remote USING THE 4 DIGIT CODE:

1. Turn your TV on.

2. Press tv on your Sky remote control.

3. Hold down select and the red button together for about two seconds, until the red light on the Sky remote control blinks twice.

4. Press tv on your Sky remote control again.

5. Key in the four digit code for your brand of TV. The light on the Sky remote control blinks twice. If the light blinks once only, recheck the code for your brand of TV and start again at Step 1.

6. Press the standby button on your Sky remote control. If your TV switches off, press select. The light on the Sky remote control blinks twice (code stored). If your TV does not switch off, press tv, then press the standby button. Repeat this (press tv, then standby) until your TV turns off, then press select (stores code).

Hi Friend,
Check your TV's remote battries. If they are good, then, power off the TV at the main wall socket and unplug the power cord, leave it for 5 minutes. Now, connect back the main power cord, hold the Power On/Standby button on your TV and power then turn ON main switch on the wall. This should resolve your issue.

Thanks,
Shiva

If the TV wont go on with the manual button on the front panel, then you have an issue with the tv set. Try a differant wall recepticle. Or unplugging it overnight. If it wont go on with the button on the front of the set after this is tryed, then its time to go to the repair shop, as the set has a power supply problem or a problem in the HI voltage/sweep circuit. Good Luck
