The standby light is on (Red), on an RCA 24V511T. There is no response at all when I press the power button to turn the TV on.

1. Turn on the TV or device you want to use with the universal remote.
2. Press and release the TV button on the RCA Universal Remote. (The red light on the remote will begin to flash)
3. Now simultaneously press and hold the Power and TV buttons on the RCA Universal Remote. The on/off button will be illuminated and then turn off. After a moment, the button will relight, it should remain on.
4. Aim the RCA Universal Remote at the TV. Release both the on/off button and the TV button on the RCA Universal Remote simultaneously.
5. Next, press and release the Play button on the RCA remote. The TV or component should turn off after about five seconds. If there is no response, continue to press the Play button until the TV or other device you are programming turns off.
6. Now press the reverse button. If the TV or device does not turn back on, continue to hit the reverse button until it does.
7. Press the stop button once the TV has turned back on, this will save the programming settings.
8. Your RCA universal remote is now ready to use

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.

First understand that you need a little patience with this remote, it's a little slow, it may take a few seconds in between pushing buttons for it to react to your TV.

1)
-Turn on TV manually first.

we're going to try and get the remote paired to your particular tv

2)
-Facing RCA universal remote towards TV, press and hold both the POWER and TV buttons on the remote at the same time.. until the RCA universal remote POWER button lights up and is constantly on.

-Then press the PLAY button on RCA universal remote

(POWER button on remote should be blinking after pressing PLAY -- what the remote is doing is trying to program your TV with a list of codes. if your TV does not automatically shut off after a minute, press the PLAY button again. your TV should shut off. wait a few seconds before trying to press PLAY button again if you need to try again.)

3)
Assuming remote turned off TV. Now let's try to get the remote to turn on your TV

On the remote at top right is a REVERSE button, press that. You should see the POWER button on the remote blink once in response to you doing that.

Watch for the power on light on your TV.. your TV may take a few seconds to power on..

Wait a couple seconds. if your TV has not turned back on, press the REVERSE button again. the POWER button should blink once again in response

If your TV did not turn on. You may have to repeat pushing the REVERSE button waiting a couple seconds for the remote to try turning on your TV. For some people this can take several times, if not a dozen times. Just be sure to be patient and wait a couple seconds in between pressing the REVERSE button again. (what the RCA universal remote is doing is going through a list of codes trying to find the right model to pair to)

4)
Assuming the remote finally turned on your TV.. We are almost done. We programmed the remote to turn off the TV and turn on the TV. now we want to press the STOP button on the RCA universal remote to lock in those codes into the remote. After pressing the STOP button the light on the remote POWER button should turn off.

5)
We are done. You should be able to change the channels and raise and lower the volume of your TV.

The Sky+ remote should automatically default to Sony TV's. Leave the batteries out for a few minutes and try again. The Code for Sony is 0000.
Or try this :-

With TV and sky box on.
Press the 'TV' button on the remote.
Hold down the 'select' and the 'red' button (of the four coloured buttons) together, until the red light on the remote blinks twice. (takes 2 seconds)
Press the 'TV' button again.
Now enter four zeros, the red light on the remote should blink twice.
Press the 'standby' button (top right).
If the TV turns off, then press 'select' and the light should blink twice again, job done.

If the TV does not turn off then press 'TV' followed by 'standby' again.
Alternate pressing 'TV' 'Standby' until the TV turns off.
When it does, finish by pressing 'Select.
Check the red light on the remote, if it blinks 3 times, then it has run out of options for 0000.
