Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

OLEDB477 DO NOT BUY IT ONLY LASTS 1 MONTH

NOT HAPPY WITH LGOLED 1/17/2025

I spent $2000 on this TV. It lasted 1 month. Now it doesnt work at all. Now Im waiting for someone to fix it. Why not send me a new one LG? 1 FREAKIN MONTH Definitely not a good start on my LG experience. Now you dont have an authorized tech in my area so Im waiting for you to find someone. Its been 7 days How hard is it to find someone? Just send me a new one and Ill send you this piece of junk back. This is unprofessional to say the least. It didnt take 7 days for you to take my $2000. Is it about the customer or the money with you? Youre happy because you got my money. This customer is not happy because I have a junk TV sitting in my livingroom now.

Great TV ... HORRIBLE Remote

Deskman1 12/19/2024

Great TV ... HORRIBLE Remote This is 2025 and LG is still using a remote from the 90s WAY too many buttons We only use 5 or 6. The settings interface is just OK. The TV Picture is beautiful. We need to get many tips n tricks from you tube. I thought that the price was about 10 too high.

Nice TV

Simi_Lisa 12/14/2024

The picture quality is great. Super easy app set up. The only bummer is my Spectrum app for my service provider isnt available. So we use the TV with a xumo account. The remote is easy to use but would like the home and main buttons to be a bit bigger.

Terrific picture awful remote

DrRK 11/20/2024

This an excellent tv set in most regards including a crisp picture with detailed renditions of sports movies and other types of programming. The one major negative is an abysmal remote control that isnt backlit making it virtually impossible to use in a very dark room and that is missing important keys including fast forward and fast reverse keys. Its really hard to understand how an electronics company can produce such an inferior remote.
