Got this set in with no LED backlights working. I stripped it down and replaced the faulty strings. Each one now lights up but when I boxed it back up there are still no backlights, sound ok and pic visible with torch. Replaced both boards on offchance but no difference. Theres a fuse on LED board but thats okay. So Im left with the panel the strings go onto or the display panel itself..any ideas welcome.
Oh and when I changed the power board the old one still had 350v across the 3 smoothing caps 30 mins later..you can guess how I found that out
