Re: LG 55LM620T-ZE Not turning on
On the N.C pin i have nothing. The text inside the box labeled CONNECTOR is taken from board. To the left inside the box there are (at least how I think it is) the suggested values for the left column of pins and the ones to the right are for the right column of pins. The numbers underthe label READINGS are my measurements of respective pin in each column....

Re: LG 55LM620T-ZE Not turning on
I saw now in my first that i wrote what could be misunderstood. To clarify, when I plug the cord in the red light goes on and stays like that until i press the power button, then it starts blinking and keeps doing that for a while before it goeas back to a static light. Some additional info is that i have a green led on the powerboard that after the tvhave been connected for about 30 secs start to blink. Blinks 5 times pauses and then 5 times again and keeps going like that.

LG 55LM620T-ZE Not turning on
Hello everyone. The tv wont turn on. It got a red standby light that blinks as when pushing power on button. The tv has been laying for about 1 year now but what happened was that i was plugging i an antennea cable or maybe vga(cant remember which one it was ) and it just died instantly. Attaching pictures of the tv and the boards. I alson took some voltage readings as in one of the attached images. Someone who can point me in the right direction on repairing it? And btw, the readings i got was when plugging the powercord in and measured it in standby mode....
