Re: LG 47LN578V - Brief Backlight flash on power up.

Hi peeps I brought a set on ebay only few weeks ago and got this problem with Back Light coming on quickly then going out so I have opened up the panel made up a test rig and found one dead led and one strip and one whole strip not lighting so I replaced single led on the one strip and found another dead led that had shorted on the other and replaced with some led's I had lying around tested all strips and they now work fine on my test rig but plug TV psu back in and i still get the exact same problem.

Please any...
