    I have just got a 55" lg tv from a friend for free it's a 2015 model. It has blinking problem. I can see what it says on the screen but blinks or flashes. Any way to fix it? Is it the power supply or LED's? 55lb5900 is the model number.

    I seen on youtube someone had the same the problem. Its the power supply over powering led's. It burns them out if you set the brightness to high.

    Does this LG set have a built-in P/S or does it have a power brick? If it's a brick, hopefully it can be replaced, but as you posted, the back-light LEDs may be damaged.
    That's sounds rather odd. The standard TV Demo Mode is usually run with maximum brightness to make the screen "pop" in the store. If this is true, it seems like any floor model LG TV would be a ticking time bomb.

    Here is the model of tv. For a better pic of the model number here it is. The power supply is on the back of the inside of the tv.
