Are you certain the replacement power supply is good? A defective main board or power supply can cause this problem.

The lights indicate what the issue is. Kind of like your check engine light in your car tells you something is wrong with the engine.

Have a LG 55ls5700 tv that doesn't turn on but the red standby comes on and when i press the power button it starts to blink

Does the screen quickly blink on and then off? Does the standby light slowly blink twice and then go out?If these are the symptoms then it is probably a bad led backlight strip.This was the fault with my lg 47ln540v led lcd tv.I have written this up in a previous post more comprehensively.Hope this helps..

TV won't turn on. Red standby light blinks

Samsung told me this was a common problem and I would have to have it serviced by an authorized repair facility.
My problem ended up being the internal power supply, but they also told me the main boards burn up.

What is the code for LG 37LE4500 TO WORK WITH SKY REMOTE CONTROL

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).
