Hi, I'm Nathan.

Hello Howard,

you mentioned the picture went out - did the sound still work?
Can you see the menu screens at all?

Customer: replied 8 months ago.
sound works and no menu.

Thanks for confirming, one last check if you don't mind - could you hold a flashlight up to the screen and tell me if you can make out any picture/menus there?

Customer: replied 8 months ago.
no picture of any kind

Thank you for checking.

Unfortunately, the issues you are experiencing are symptomatic of an internal hardware defect, meaning a faulty tcon board or main/control board, though there are many possible failure points. This issue could be a manufacturing defect, but is also often caused by a power event (shock/surge, prolonged over/under voltage condition, etc).

This could also be the result of age related wear and tear; even on a 3 year old tv, that type of failure wouldn’t be surprising. These tvs, and all modern flat screen tvs have an designed service life of about 5 years, with anywhere from 3-5 being typical. This is not unique to LG, in fact they are actually the most reliable brand on the market, along with Samsung. With most other brands you'll get even less.

There is one step you can take here, both as a possible fix, as well as a diagnostic evaluation:
1) Unplug the power cord from the outlet

2) Wait at least 1 hour (60+ Minutes)

3) Press and hold the power button (on the set, not the remote) for 60 seconds
4) Keep holding power button while plugging back in, and for another 60 seconds after. When plugging back in, go directly to the wall outlet, bypassing any power strips or surge protectors.

If this reset process does not work, it would unfortunately confirm an internal hardware failure.

This is something that would require repairs to correct; if you're thinking about a do it yourself repair, you'll need to be comfortable and skilled with electronics repairs, which could include dismantling the set (removing the back panel of the tv), diagnostics testing with a multimeter, changing out boards as needed, and possibly desoldering/removing and soldering/replacing individual components.

If you’re considering repair at a local shop, you’ll find a typical repair to be around $300 for diagnostics, parts, and labor.

For a tv of this size/age however, replacement will make more sense. You can get a brand new LED tv with a fresh warranty in the $400 range. Prices have come down quite a bit even since you bought this one.

I can help you with finding parts, finding a repair shop, or recommending replacement options, if desired.

My apologies for the news.
