LG 42LM760T-ZB Lines on Screen (Hello friends - need some help please)

[dangerboy]

Hi All,

I have a 42 inch LG 3D LED TV. Model no is 42LM760T -ZB,

My issue is a weird one that just started happening. I suspect my mom in law hates me and tried to break my TV lol.
I Can see evenly spaced horizontal black lines right across my TV from left to right on the entire screen. These lines are all 180 degree lines and are not very noticeable from far away but close up I can see them.
I have tried taking all cables out apart from power and seeing if it's possibly interference, but it wasn't. I've also tried using another power point, no luck.
I'll upload some photos to.
I've read online and 50% of the comments are telling me its possibly a TCON board or the connectors, but wouldn't that just affect half the scrrent? Most other comments point me to believe that my Led screen is broken. It socks because its only 2 years old.

Any ideas?
Thanks for your help

Don't worry I edited the title for you.

The fault is a crap shoot... On the Samsung sets displaying this it's pretty much been a panel fault i.e. non repairable.

I've not yet seen an LG panel show it, so you might be lucky with a T-con but my gut hunch is it's a panel problem (I don't think your mother-in-law could cause this )

You could try a test - we will need a photo of the T-con board in the set.

Its a high possibility its the panel itself. I wouldn't recommend that you spend money on trying to find out.
--Has this set a separate T-Con, or is it integrated into the panel tab board?

Unfortunately it seems the more recent the set these days--The more Crap/unrepairable it is--no matter WHAT make.....

Thanks for edit! ,
ahhh, that's a shame. Yeah, I haven't seen a real fix for this issue onlin. I might give the board a go. I'm in the UK, so need to shop around.

Anyone else? What's your thoughts?

As I said, there's a test you can do that might help rule out the panel, but you'd need to open the set up and get us pictures of the T-con. It involves disconnecting some ribbon cables and seeing how the display changes.

OK, sounds like a plan.

I can open it up this evening and take some pics.I've seem a few "how to disconnect the connectors from a TCON Board" vids

Anything else you would need me to do?
