Some Issues

[This review was collected as part of a promotion.] I'm having an issue with the TV - automatically turns itself on, automatically pauses, automatically unpauses, automatically unmutes itself. Samsung replaced the main board, but the issue still persists. Other than that, the picture and sound are great.

65 inch Samsung TV review

[This review was collected as part of a promotion.] TV picture is good. Remote is not as comfortable as previous models. Remote connection is weak and requires you to be in close proximity to function. Very irritating at times. TV is slow to respond when switching to a different application.

I absolutely love how slender the remote is.

[This review was collected as part of a promotion.] I love this television quality and the surround sound factory speakers built in. It's easy to adjust the viewing of each show if the quality of the movie is low. Putting a passcode on certain apps helps prevents my children from seeing inappropriate things. I can set the visuals on different perspectives. The light effects are incredible.

Network tends to drop while streaming in apps

[This review was collected as part of a promotion.] This TV is aesthetically quite beautiful and has great resolution. I love the image quality and how quick and easy it was to set up and link to the Samsung phones in my house with the SmartThings app. The brightness gets quite bright which is great because my living room it is in is very dark later in the day but I will say that if I have the recessed light turned on just above the mounted TV, it tends to wash out the image and create a glare (as lights tend to do). The colors are bright and vivid on the picture and I feel as though my Samsung Account is secure being linked to the TV. My one main complaint is that every so often (about once every 2 hours) I lose my network connection. Sometimes it is only for a second or 2 before it reconnect and other times, I have to either change the channel on whatever app Im using or I will have to back completely out and restart the app I'm using. I have sat and waited for it to reconnect and if I'm in Samsung TV Plus, it will at times not go back to the programming unless I physically click a button... which isnt too big of a hassle, it just feels unnecessary as an older Samsung TV I used to have was capable of never losing my network connection. (And I want to mention that I have made sure it was not because of my home internet provider and have the router directly underneath of the TV and have used all different Ghz wifis to try and make it stop with no change.) Overall, it is a solid TV that I enjoy. The sound could be a bit louder for such a large TV but I still am very happy with this TV and would recommend it to friends and family.

Won't link to any wifi

[This review was collected as part of a promotion.] I've been buying Samsung TVS for a long time. Enjoy the quality picture and everything about them. I recently purchased this new TV replacement that had broken on my outside patio I was a little taken back by the new style remote but being I have a roku TV I was able to figure it out quite easily. The problem I have is my tv will not pick up any Wi-Fi anywhere so as it stands, the only thing my TV picks up is digital TV from the antenna will not pick up any internet so I can't get any of my Samsung channels, my Netflix or any other apps that I have set up for my other televisions and it's very discouraging, and I can't figure out why I've done every steps. That I've seen to get remedy of this situation, but nothing seems to happen.I just wish someone could give me a hand with this.So I could get this t v working like I wanted to.

Hi Upsettvbuyer, Thank you for sharing your experience with Wi-Fi connectivity. If your TV is having trouble connecting to the network, the following steps may help resolve the issue: Signal & Setup Tips: 1. Check TV-to-router distance – Your TV should be within 50 feet of the modem or access point for reliable signal strength. 2. Minimize interference – Turn off nearby wireless devices and make sure there are no physical barriers (stone walls, fireplaces, appliances) between the TV and router. Power Cycle Devices: 3. Restart both your TV and router – Unplug both devices for at least 30 seconds, then plug them back in and allow them to reboot fully. Connection Type: 4. Evaluate your connection method – o If using Wi-Fi, move your router closer to the TV and eliminate any obstructions. o For a more stable connection, we strongly recommend using a wired Ethernet cable. o If already using Ethernet, verify the cable is working by testing it with another device. Run Built-In Diagnostic Tools: 5. Network Test: Settings > Support > Device Care > Self Diagnosis > Smart Hub Connection Test 6. Wi-Fi Check: Settings > Support > Device Care > Self Diagnosis > Wi-Fi 7. Please ensure you are running the latest Firmware. Go to Settings> Support> Software Update. Last Resort: 8. Perform a Factory Reset (if issues persist): Settings > All Settings > General & Privacy > Reset > Factory Data Reset. Note that this will return all settings to their original defaults. If these steps don’t resolve the issue, please reach out to Samsung Support at 1-800-SAMSUNG, available 8AM – 12AM EST, 7 days a week. LiveChat support and additional help are available at the ‘Support’ link on our website. ~Samsung Advisor

Crystal tv

[This review was collected as part of a promotion.] I couldn't be happier with my Samsung 75-inch U7900 Crystal TV. The 4K picture quality is incredibly sharp, and the vibrant colors bring everything from live sports to movies to life. Its massive screen size paired with a sleek, bezel-less design completely transformed my living room into a home theater. The smart interface is fast and intuitive, making it effortless to jump right into my favorite streaming apps.

The Samsung is a good budget-friend

[This review was collected as part of a promotion.] The Samsung UN55U7900FFXZA is a good budget-friendly 55-inch 4K smart TV that works well for everyday viewing. It offers a sharp 4K picture, easy access to popular streaming apps through Samsung's smart TV platform, and decent performance for casual gaming. The TV provides good value for its price,

Decent for the price

[This review was collected as part of a promotion.] Beautiful picture, easy to set up and pair with Amazon fire cube and remote. Sound quality is poor. We had to turn it up to 56 dcb for standard volume that most TV's would be at 12-16 dcb. We added an old sound bar which has helped. The back of the unit is rather fragile. We mounted this new TV to an existing wall mount and noticed how much the material flexed while attaching the brackets. We were afraid it may crack. Got it put up and beside the sound issues, it is a decent TV for the price.

Hi Lores, Thank you for purchasing Samsung’s U7900F TV and for sharing your feedback regarding low volume. To start, we recommend making sure your TV is running the latest firmware, as updates can include improvements to sound performance: Home > left directional key > Settings > Support > Software Update If volume levels still seem too low, you can improve sound performance by adjusting a few key settings: Sound Mode: Navigate to: Settings > All Settings > Sound > Sound Mode Auto Volume: This feature helps maintain consistent volume levels across content and input sources. Turn it on under: Settings > All Settings > Sound > Expert Settings > Auto Volume = On You can also explore Expert Settings to fine-tune sound output with adjustments for Balance, Equalizer, and more. If you’re considering enhancing your setup, Samsung’s Q- and S-Series Soundbars feature Q-Symphony, which syncs your TV and soundbar speakers for a fuller, more immersive sound experience. For personalized support with these settings or selecting a soundbar to complement your setup, contact Samsung Support at 1-800-SAMSUNG (8AM – 9PM EST Mon – Fri, 8AM – 6PM Sat – Sun) or use LiveChat via the ‘Support’ link on our website. ~ Samsung Advisor

Samsung 75 inch

[This review was collected as part of a promotion.] Easy to use layout of apps can connect my laptop or phone very easily. Great picture quality and can’t beat the price. Definitely needs a soundbar though although I think almost all large flst screens do now a days.

Every thing except the remote

[This review was collected as part of a promotion.] I love the picture in the Samsung television. The only thing that I do not like is the remote that came with it. I don’t like the volume controls. It’s hard to mute. Especially if you’re on live television.
