Problematic TV. A few months old and constant issues. Shuts off, memory errors when watching a program. Disconnects from network. Don’t recommend at all… Factory resets, updates not helping.

Hi, Daniel. Thank you for sharing your experience with your LG TV (OLED77B5PUA) model. We understand the importance of having a TV that performs reliably, especially when it’s only a few months old.
Power interruptions, memory errors, and network drops can sometimes be linked to external factors. One helpful step is to unplug the TV for at least 60 seconds, then plug it directly into a wall outlet (not a power strip) to reset the power supply and clear temporary system data. For more guidance, visit https://www.lg.com/us/support/product/lg-OLED77B5PUA.AUS. If the issues continue, we’d be glad to take a closer look. Please send us an email at lgdigitalcare@lg.sprinklrsupport.com so we can assist you further. ^Juvy

Hi, Colts. Thank you for sharing your experience with your LG TV (OLED77B5PUA) model. We understand the importance of having a smooth and reliable delivery process, especially when you’ve adjusted your schedule multiple times and were billed for services that haven’t taken place.
One helpful step you can try is checking the order status and service charges directly through your Best Buy account or contacting their delivery support team to verify the billing and ensure the delivery and installation are properly scheduled. You can also contact their customer service at 888-237-8289. You can also review support information for your TV model here: https://www.lg.com/us/support/product/lg-OLED77B5PUA.AUS.

The entire delivery experience was horrible. Zero communication, delivery dates not followed, 2nd attempt once again were able to complete delivery day 2, then it was still deliver an hour outside of the latest 12 hour timeframe. Highly upsetting with how bad the communication and follow thru was with a company as this
Posted
Hi, Graham. Thank you for sharing what happened with the delivery of your LG TV (OLED77B5PUA) model. We understand how important clear communication and timely follow‑through are, especially when you’re expecting a new TV.
While delivery services are handled by the retailer or carrier, we’d still like to help you move forward. One thing you can do right away is check the Order Status or Delivery Tracking page from Best Buy customer service at 888-237-8289 to confirm the most up‑to‑date delivery notes, as these pages often update faster than automated notifications. If you’d like us to look into this further or assist with next steps, please send us an email at lgdigitalcare@lg.sprinklrsupport.com. ^Juvy

Within the first hour a line about an inch from the bottom appeared all along the screen. Then about 15 mins later the tv just went black and quit working. Its been over 10 business days since the return and still waiting for refund. Customer service over the phone is a nightmare with Best Buy.

Hi, there. Thank you for reaching out. We understand the importance of having your new LG TV (OLED77B5PUA) model work flawlessly right from the start, and we appreciate you sharing what happened with the line on the screen, the sudden shutdown, and the delay in receiving your refund.
For future reference, one helpful step you can try is checking whether the power cable is fully seated on both the TV and wall outlet side, as a loose connection can sometimes cause the screen to go black unexpectedly.

TV went out in 10 minutes and would not turn back on. Best Buy was great with return, but I upgraded to the C5 instead no issues beautiful picture.

Hi, Chris. Thanks for sharing your experience with us. We understand your LG TV (OLED77B5PUA) model went out after 10 minutes and would not turn back on. It’s awesome to hear that you’re loving your new C5 model without any problems.
Even though you’ve figured things out, a chill troubleshooting tip for a TV that’s being a bit stubborn about turning on is to do a power cycle. Just unplug the TV, hang tight for a minute, and then plug it back in. Sometimes that little reset can clear up minor hiccups.

TV broke and needs repair in the first month we purchased it. You took zero responsibility when we called you. We have been loyal customers of BestBuy for many years but that's now over. Horrible experience with this very expensive recent purchase.

Hi, Arlene. Thank you for reaching out and sharing what happened with your LG TV (OLED77B5PUA) model. We understand the importance of having a new TV perform reliably right from the start, especially with a premium model like this one.

This helps refresh the internal system and can resolve issues that appear early on. For more guidance, visit https://www.lg.com/us/support/product/lg-OLED77B5PUA.AUS.

We bought this tv on Oct13th for $1599.99 at BestBuy store. When we checked online on Oct31st the price was $1,499. When we called customer service they put us on hold for 35 minutes stating they are working on it and then came back stating they cannot do a price match or provide a credit for the difference….while the website states that they do the price match during holiday period…so, frustrating in wasting the time and keeping on hold. TV is fine. Picture quality could be better
Posted
Hi, Srini. Thank you for sharing your experience with the LG TV (OLED77B5PUA) model. We appreciate your feedback and are glad to hear the TV is working well overall, even if the picture quality didn’t quite meet your expectations.
For optimizing your viewing experience, we recommend enabling AI Picture Pro under Settings > Picture > AI Service. This feature automatically adjusts contrast, sharpness, and color based on the content and ambient lighting. You can also try switching to Filmmaker Mode for more accurate color and motion handling, especially with movies and streaming content.

I am not recommending the LG TV model specifically, as it does not support 4K film playback (2160p). Models B5, C5, and others are affected by this issue.
Posted
Hi, there. Thank you for sharing your detailed feedback on the LG OLED77B5PUA and related models. Your experience highlights an important concern for users who expect full compatibility with 4K (2160p) film playback — especially when investing in a premium OLED television.
It’s clear that resolution support plays a major role in your viewing experience, and your observation that certain models like the B5 and C5 may not deliver the expected playback performance is valuable. We’ll be sure to pass your feedback along internally so it can inform future product development and support efforts. Thank you again for taking the time to share your experience — it contributes meaningfully to improving both products and communication. - Avril

It took a total of three visits by the Geek Squad to figure out why my new t-v wasn't communicating with my receiver. The whole process was frustrating and took more than a week to correct or understand why.
Posted
Hi, Dwane. Thank you for reaching out about your LG TV (OLED77B5PUA) model. We understand the importance of having your new TV communicate smoothly with your receiver, especially when you’re excited to get everything everything set up and working together.
One helpful step is to verify that the HDMI port used for your receiver supports eARC and that Simplink (CEC) is enabled in the TV settings. This ensures proper audio handshake and can prevent communication delays between devices. You can also review additional setup guidance here: https://www.lg.com/us/support/help-library/lg-tv-connecting-a-hdmi-device--1405576683065.

The tv was supposed to come with an additional tv, which was then cancelled. I would not have purchased this specific TV if the promo of the free additional TV was not going to be honored. I am a long time customer of Best Buy and unless resolved will take my business elsewhere.

I bought this LG TV on 1/21/26. Since it was delivered to the wrong address, I can't rate the tv. However I can rate the customer service for Best Buy as absolutely terrible. I cannot get any help with my refund All I can get is frustration at the ineptitude of Best Buy. Today's date is 3/8/26
