Have a standby light blinking twice with no picture

The power supply is failing.

do you have a dim screen? if you put a torch to the screen at an angle can you see the picture?if so this means the backlight is out, it could be the inverter board or the bulbs themselves though this is unlikely.do you get the 24Vgoing to the backlight from the psu?

set should have come with a one year warranty.

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).

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.

This blinking is a diagnostic code. Please update this with the model number. These sets contain circuitry that will shut the set down and display a code like this when a problem is detected. With the model number, I can look up the problem and provide potential repair suggestions.

Thanks,
Dan

sony KV40XBR700 tv no picture but sound is on, standby light blinks 6 times

I've got exactly the same problem. Initially, I saw it flashing twice, pause, twice, pause, twice... I pulled the plug when it failed to respond at all. And then when I plugged it back in, it went into the continuous flashing mode. Halp!

Is your model KP61HS10? If so I can help you?
