LG 47LE5900 no picture

[Bloopeta]

Hi, I have an lg 47le5900, when you turn on the TV, it starts up fine, LG logo screen comes on as normal, but then nothing, just a blank screen, but a blue line down left side and yellow line down right side, backlights are on

Have cleaned all plugs n ribbon cables to no avail.

Any help greatly appreciated

Bad solder on the main processor under the large heat sink in the middle. It needs to be either reflowed (not a reliable, long lasting option) or reballed (much better option but way more difficult).

Couldnt get lines to go off, so removed bezel and metal frame from around LCD panel, ran a thin line of black insulation tape down each side, reassembled, now cant see lines and tape is barely visable.
