Lg 52lb9df Is it High definition

I can't find an LG 42LN543N-28 listed anywhere. The 42LN5400 has a full HD display (1080); this model sold in the UK was labeled the 42LN543V. Thus I suspect that your model also is a HD TV.

Any screen with 720 rows of horizontal pixels or more is usually called a high definition TV or monitor (depending on the inclusion of a TV tuner). The 42LN5400 display has a 1920 x 1080 maximum resolution.

I hope this helps.

try going to onscreen menu , scroll around till you find a caption option and turn it on
some remotes for the tv will have that option in a button

It depends on your source video resolution. If you're willing to play in 4K, you can upscale your 1080p or 720p video to 4K resolution in advance. Here is the video tutorial:
After conversion, it will be played in 4K on your TV. Of course, it's all based on that your TV supports 4K.

The contacts between the carbon of remote and the rubberized button could be faulty.

Yes it can be destroyed all the hdmi inputs end up in a chip called high definition controller before going to the main video prossesor so it might be destroyed or all the mainboard might need replacing

I googled your model and it took me to a link that provides an owners manual to find the exact bolt pattern of the mount.

1. Your TV has a digital tuner built-in, you do not need a set-top box to receive local digital channels.

2. Try to disconnect the box, hook up the antenna directly to the TV antenna input & program the tuner, you may getting better picture.

If you were to log on to the lg.com web site, I think you will be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, list of Dealers for spare part supplies and Driver downloads as required.

The information is normally free of charge.

I hope this helps.

you need a codex. search on dowload.com and look and type in divx on the search bar. download it from there and install it.

This is unlikely Verizon's problem.

Does the delay occur with non-TV sources like DVD player or video games?

If so, that's the LG firmware.
