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.

Best TV LG used to make

Clifff Richard 12/16/2023

Best TV ever made. Amazing blacks and colours can be used as a gaming monitor as well as movies. Amazing sound. Replaced by the C1 2 and 3 all which were far inferior and after trying them Ill never buy

Premium Price Pitiful Performance

AshJith 12/2/2023

I am utterly disappointed with my purchase of the LG OLED 65 CX PUA a TV that came with a hefty price tag of $3000. I expected a premium product that would stand the test of time but my experience has been nothing short of a technological nightmare. After just 2 years of use the TV developed a frustrating vertical line issue. While annoying I was willing to overlook it as long as the TV continued to function. However the real nightmare began at the 3-year mark when the TV abruptly shut off during a viewing session. Attempts to power it back on were futile as a persistent vertical line appeared before the TV automatically powered down rendering it completely unusable. I reached out to LGs customer center hoping for a solution or at least some assistance. To my dismay I was informed that the only remedy was to replace the board a fix that would cost me more than half of the initial purchase price. This response is nothing short of outrageous and entirely unacceptable for a product marketed as top-tier. For a television that boasts cutting-edge technology and carries a premium price tag the lifespan of a mere 3 years is nothing short of a betrayal to consumers who expected longevity from such a significant investment. LGs lackluster customer support only adds insult to injury. I strongly advise potential buyers to reconsider investing in the LG OLED 65 CX PUA unless they are prepared to endure the frustration of premature failures and the exorbitant costs associated with repairs. This experience has left me questioning the quality and durability of LGs products and has certainly eroded any trust I had in this brand. Buyer beware this TV is a costly disappointment.

Great Picture - Worth the wait

hjfcfo 9/9/2023

I bought this TV mid-2020 after waiting for it to be available in this size 48 for quite some time. WORTH THE WAIT. Picture is crystal clear amazing Viewing angle is superb. No noticeable reflections in a well lit living room with a wall of windows. We watch a lot of tennis so seeing the ball well is very important. Theis TV DELIVERS

Great all purpose display

Yueholiday 8/21/2023

Bought this a couple years ago and its been fantastic. Use it as my main display for gaming movies and productivity. Nothing quite beats OLED at 120hz and using it as a monitor makes it the equivalent of having four 24 1080p 120hz OLED panels in one. That said I was more impressed with LGs warranty. When I experienced some burn-in they sent a technician to replace my panel within a few days free of charge. Nothing really to complain about.

Good but the support is non-existent

springjade2009 12/26/2022

Have enjoyed the television but support has been non-existent. Had a problem with muting appearing on screen after one of the updates before the current one and couldnt find out what to do short of restoring the programming. Not techies so it would costs a lot just to have to realign the television with our sound system since wed have to hire someone. Not sure what happened but the muting on screen went away but now it doesnt displaying at all. Not anxious to tinker at all.

Love Our LG

Andrew N 11/7/2022

Weve been enjoying our OLED48CXPUB for over a year. Beautiful image quality. Really stunning. We use a wall mount above our fireplace which also look classy. The only slightly negative area to call out is the cumbersome smart TV interface. We have been using the Google Chromecast streaming interface which works very nicely with the LG.
