  I have a lenovo Legion pro 5 16ACH6H with AMD RYZEN 7 5800H and RTX3070,.

  Lg 47lm860v 3d tv- no picture

  by Longon

  Re: LG 47 LM8600 - No Video Hi all.....
  I probably need putting against a wall and deserve a stoning for my stupidity.............. I have a LG which after following information with problems with T-con and lines on screen covered the pins which affected the display and had it sorted...until!!! Lets get it over and done with, I managed to get a little sidetracked and forgot that the tv remained powered up and I replaced the LVDS which to my horror then left me with no picture whatsoever. The backlight remains ok but as mentioned no picture and probably managed to fry the T-con or have...

  New Members - please post your introductions here

  by petabyte

  As this is a brand new forum, I thought I'd open up a thread to encourage new members to introduce themselves a bit.. now hey.. let's not get too personal.. ok ?

  My name is petabyte and I'm a forum junkie. :oops: I've been off the wagon for a number of years and countless times I've tried to stop but it's useless.....

  LG 82UN8570AUD ~ TCON or PANEL?

  When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.
  
  I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped...
