I know if the connections are not set right, you will get that scenario. I know there are a number of TV inputs with this TV Set and I don't even use 3/4 of them. I guess I'm a dumb operator with a "smart" Tv. Read and re-read directions. I'm not real savvy on this stuff, but, if all else fails, contact LG for support.

The "No Signal" lettering usually appears when the input (found by clicking input) cannot find a source. To have a source make sure all audio and video cables are connected or USB or HDMI cables are connected. Once this is done go to input to see if your source is connected. Sometimes if a source, for example an x-box 360 or your satellite/cable tv, is off or disconnected you will see the "No Signal" lettering. So, make sure all cable inputs are in and that you selected the right input on the list (after clicking input) and that the power of your source (TV, game system, DVD/Blue ray player) is on. Hope that helps... The "No Signal" lettering usually appears when the input (found by clicking input) cannot find a source.

Without more details I can only generalize. Check all signal connections. Check to see if changing input then back again helps.

Unplug the power and plug it back in. If you don't see a picture, it might be stuck in the wrong video mode. If it is, you might not be able to fix it without plugging it into a television that supports the mode it is currently in.

Unplug the lcd connector and plug it back, but if that doesn't work probably is the lcd problem, try with different lcd

Hi, I´m sorry but I don´t really know. I have the 8600 55" and works perfect. Maybe you should consult at LG website.

I have an lg g2 and i have had to turn off my phone and tv hook up the cable. Then switch to the correct hdmi port. Hope this helps. Also make sure your phone case is not preventing the usb from making a good connection

Had the same problem. Left side of screen went totally black. Vizio Techs could not help -returned to Sams club.

I'm having the same problem at this time (S2) and it's only showing a black screen when I hook it all up.

I don't know what programs you have tried, but use the LG software first to make the BD readable and playable, then you need to use a blue ray playing program such as Roxio or Power DVD etc.

Unplug it, wait a minute or two and plug it back in. I had this problem as well and it was happening a lot, so I returned my tv for a LG...great move, no problems since.

Dena I can't answer that question for you. My LG32 has never needed service or shown an trouble issues. I would suggest calling customer support for LG and see if they can help and if they cannot resolve and the unit is out of warranty then seek a qualified repair facility. Sorry

LG BD270 Blu-ray Disc PlayerI experience picture freezing after 17 minutes on the LG. Perform a skip back and the picture would freeze again, etc. Tried powering off and playing again, still the same problem. Any one else have this or is it unique to this unit?

Could you please elaborate? Hardware specs? Firmware versions? Exact nature of the problem?

I'm not sure if this will help this problem, but LG does have a new firmware update for this player. It can be found on their website LG_BD_7303M51.ROM. It's a pretty recent update that came out on 12/5/12 so it may fix the problem. Here's the link: http://www.lg.com/us/support-product/lg-BP200#

try to reset the device by unplugging it and plugging it back in. also, make sure you take the tiny protective cover off of the end of the optical cord that plugs into your tv. its small and very hard to see.

Brian, If you haven't noticed yet, LG has fixed the problem with new software version 8.00.11. Thanks.

According to LG's own website, the refresh rate is listed as 120hz. Whether or not it is, I don't know. There are no TruMotion settings in the menu of the 42LN5400.
