Home Delivery Nightmare
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.On Black Friday, I ordered a 70" Samsung TV. On 12/2/25, the TV was delivered to my home with a broken screen. I loaded the TV into my truck and returned it to our local Best Buy. The manager at Best Buy said that this order was still showing a status of "out for delivery" so that can't take the TV back. So, I had to load this TV back into my truck and return home. Then, I called Customer Service and scheduled an exchange to happen on 12/24/25. Then Best Buy rescheduled this delivery to 1/8/26. On 1/7/26, I received a notice that the delivery needs to be rescheduled for a fourth time! Now, it's 5+ weeks and counting.

Marginal service
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Bought a 70 inch a 50 inch and a 32 inch, voice wouldn’t sync on news broadcast and the TV did a few other weird things too like going back to the homepage in the middle of a hockey game. Supposed to get a call within 12 hours so they can come out and replace it three days and still waiting. That was after a trip to town to the store who said I had to call the 800 number. The 800 number sent me back to the website and then spent 40 minutes on chat to get it accomplished. Chat sent it back to the local store to coordinate and schedule the replacement.

Don't buy

Posted .Hi DebraR,
Thank you for sharing your experience with the internet connection on your Samsung U7900 TV. Whether you're using Wi-Fi or a wired (LAN) connection, there are a few steps you can take to help resolve the issue:
1. Power Cycle Your Equipment. Unplug both your TV and router/modem from the wall outlet. Wait at least 30 seconds, then plug them back in and allow both devices to fully restart.
2. Check the Network Status. On your TV, go to: Home > left directional key > Settings > All Settings > Connection > Network > Network Status. This will help determine if the issue lies with the network or the TV.
3. Try a Different Connection Type. If you're using Wi-Fi, try connecting an Ethernet (LAN) cable directly from your router to the TV to test the connection. If you're using a wired connection, try switching to Wi-Fi to see if the issue persists.
4. Reestablish the Network Connection. Go to: Settings > All Settings > Connection > Network > Open Network Settings, and follow the prompts to reconnect to your Wi-Fi or wired network.
5. Update Firmware. Software updates can often resolve network bugs. To check for the latest version: Settings > Support > Software Update > Update Now
If these steps don't resolve the issue, we’d be happy to provide further assistance. Please call Samsung Support at 1-800-SAMSUNG, 8AM - 12AM EST, 7 days a week. LiveChat is also available at the ‘Support’ link on our website.

Samsung U7900F 70"
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I would never buy a model of this type again. It only came with two HDMI ports and had no headphone jack. Also, the volume control is limited to high or low, but no in-between.
No, I would not recommend this to a friendBrand response from Samsung
Posted .Hi JimK,
We appreciate your feedback on the available inputs on the U7900 TV. If a headphone jack is important to your setup, this input is found exclusively on our S90F OLED series.
If the volume on your Samsung U7900 TV seems too low, we recommend checking for firmware updates: Settings > Support > Software Update > Update Now.
Then, go to: Settings > All Settings > Sound > Sound Mode and try Amplify to boost dialogue and upper tones.
To maintain consistent volume across channels and apps, enable Auto Volume under: Settings > All Settings > Sound > Expert Settings > Auto Volume = On
Samsung Q- and S-Series Soundbars with Q-Symphony can also enhance your sound experience. For further help, please contact Samsung Support at 1-800-SAMSUNG (8AM – 12AM EST, 7 days a week) or use LiveChat via the ‘Support’ link on our website.

70 in samsung
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Bought this at the store and after installing it at home it worked great for about 9 hours and then quit working completely would not even power on. I returned to store but the unfortunately did not have another in stock so I wound up downsizing to a smaller model so far it has performed very well. I wanted the larger one but wasn't able to wait a week for another one.

New TV unlocked!
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I love my new TV! It's bright and exciting. My grandson thinks the game app is fun. There was a little trouble to set up due to me not remembering my Samsung Account, but we figured it out. I'm very happy with all of the viewing options available.

Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.For the value, this is a great tv. It isn't the top of the line, but for our use it works perfectly.
I would recommend this to a friendToo few ports
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Ordered this TV in the middle of December. Took about two months to come into the store. Went to set it up only to realize it doesn't have an optical input for my soundbar. Only has one regular HDMI and one earc HDMI. Plugged soundbar into the earc port only to find out the sounbar isn't compatible. So had to use Have a Blu-ray player to go into the second earcHDMI port. Now this leaves no port available or my ROKU(which technically I don't need on a smart TV) and no port for a game console. I can't imagine it would have cost Samsung more than a few dollars to at least include an optical port and a third HDMI. My fault for not checking all the specs, but I've never had a TV with only two ports. I've only owned Samsung TV's.
