Hi Folks ,
I have a 75 inch Led Lg tv
Model LG75SK8000PTA
that has a strange problem
i have no sound no picture ,
i can turn it on and the backlights come on and I get a very dull Blue screen
when I use the remote I can see a response like its trying to show a picture on screen but cant get a image just very dark shadows moving around the screen
I have checked all the smps voltages are all ok and present
I have replaced the Tcon board with a new one from LG
I have checked and cleaned and reseated SVDC cables
I have 12v at SMD fuse on both sides at the tcon board
so I think I have a good Main and tcon board signal present
my backlights seem bright enough from the back of panel when looking at them
what could be the issue
Can i follow the LG tcon test as per the training Manual on here
your help is appreciated
Thankyou
