Re: LG 42LC7D Black Screen (No display)
Just an update. On the main board there is a green button, if I press it while the TV is on, pink & red diagonal lines flash on the screen and then flash off, and the speakers make a noise too... is this of any help?

Re: LG 42LC7D Black Screen (No display)
hmmm, I understand your point but why wouldn't I see any change whatsoever after replacing bulged caps with these, at least momentarily at the least? Not trying to hassle you, just trying to understand a little better, and am kinda broke right now so wondered if there is anything else I can do to find out what may be causing this issue besides caps, if it isn't caps....Leave a comment:

Re: LG 42LC7D Black Screen (No display)
The guy I go to is a sub-business of JayCar (only orders some stock from JayCar), he orders caps elsewhere from another guy. He said they'll be good for what I want them for. He also ordered caps with a 10v increase (eg, replaced 25v with 35v) for me....Last edited by kilooonl; 08-07-2013, 09:04 AM.Leave a comment:

Here's some pics.
Although it may not look like it, on the picture showing the TV on, the back light is visible on the entire TV, not just the bottom half. My camera is horrible :P Also on the pink cable where it shows a mark, that is heat shrink where I stripped it and re-soldered it as it looked like it was damaged/cut beforehand, so I re-soldered and used heat shrink to fix it just in case.Leave a comment:

LG 42LC7D Black Screen (No display)
So I got given an [URL="http://www.lg.com/au/support-product/lg-42LC7D"]LG 42LC7D 42" HD TV[/URL].
The issue with it is that when you turn it on, the green LED blinks 8 times before remaining solid.
After which, the screen remains black. Just black. However the back light works as you can see the streaks of light.
Before it was given to me it would take about 5 minutes to "warm up" (display picture), after some time it stopped warming up and that is when it began doing what it is now which led me to believe capacitors.
