I should also include...

I can't believe how many people have issues like this with their 5 year old LG TV. There should be some type of recall. I can't imagine that many good bad by the same problem after only 5 years and from a legitimate manufacturer.

Have you tried rebooting your router, then trying to connect the TV to the router and internet?

Thanks!
We have the 55LW5300 which is basically the same TV. Purchased in 2012. Around 2014 it died, no logo, nada. Since you're occasionally getting a LG logo, I would suspect the power supply board, which I replaced on mine (uses the same power supply board, IIRC).

I laid it flat on the bed, face down, unscrewed the back cover, and there are two large boards -- power supply and main. Marked all of the connections, pulled them and found a replacement PS board on Ebay for $85. Got the board, swapped it out, fired it up and everything's been good since then. (Much easier to fix than our old Pioneer 503PU with its Media Center -- gotta be a dozen unobtainable boards going on there.)

Actually it is a brand new router we are using today so it should be fine. Problem started last week.

Ok so my 55LW5600 just started having major issues. I blame it on all those talking about their issues on this forum!

All kidding aside, when turned on, it would have black/white squiggly horizontal lines, flash red, green, etc... Then go blank.

I searched the internet and found one potential fix if it is the input board that is having the issue, which seems to be the most common. I think its called the T-com board.

So I followed the directions of removing the board and placing it in the oven at 385 degrees for 10 minutes. Yes, my wife thought that I was insane "baking" the board.

Once cooled down I put the board back in, plugged all cables back in and was ready for the test...

I turned it on and low and behold, it flippin' worked... The oven trick had successfully "reconnected" the issues that the board was experiencing.

Just wanted to pass this along in case any one else is having an issue since it seems to be such a common 5 yr issue. Hopefully I don't have to bake it for some time again.
