Not Happy
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I really like the TV to a point I tried to work through it because some channels through the apps do well however, I'm highly disappointed with some of the functions such as a very slow response time and it lags; sound don't match the character's lips, and some channels don't come in as clear as others. I'm wondering if I got one with some sort of cliche

Dissatisfied
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Don’t make the same mistake of thinking you can get a tv with no issues on the cheap.. I decided to go against my instincts and see if I get a good 75 inch tv for under $500 .. Problem after problem ensued so unless you’re very tech savvy, pay the extra $200-300 to buy the better tv !!

Posted .Hi OdellL,
We’re sorry to hear you’re not fully satisfied with the picture quality on your Samsung U7900 TV. If the image appears too dark, we suggest disabling certain energy-saving features, which can automatically adjust brightness and affect how the screen looks.
Go to: Settings > All Settings > General & Privacy > Power and Energy Saving, then turn off Brightness Optimization, Energy Saving Solution, Motion Lighting, and/or Contrast Enhancer.
You can also adjust the Picture Mode to better suit your environment: Settings > All Settings > Picture > Picture Mode
• Standard – Default mode for general viewing
• Dynamic – Brighter and clearer, ideal for well-lit rooms
• Movie – Best for dark room viewing
• Eco – Energy-saving mode
• Filmmaker Mode – Preserves content as intended by creators
To fine-tune brightness, go to: Home > left directional key > Settings > All Settings > Picture > Expert Settings, then adjust the Brightness level (0–50) to your preference.
Lastly, please make sure your TV is running the latest firmware: Home > Home > left directional key > Settings > Support > Software Update > Update Now

We’re sorry to hear about the crack that developed on your screen. While we understand this is frustrating, it’s important to note that screen cracks do not occur spontaneously.

As this type of damage is not the result of a manufacturing defect, it is not covered under warranty. Our warranty applies only to defects in materials or workmanship encountered during normal, noncommercial use.

Posted .Hi DominicB,
We're very sorry to hear about your experience. If your TV is displaying a red tint on the screen, we recommend the following steps to help isolate the issue:
1. Check all input cable connections for any external devices (e.g., HDMI, streaming boxes, Blu-ray players)
2. Switch channels or inputs to see if the issue appears across all sources
3. Run a Picture Test to check for panel-related issues: Settings > Support > Device Care > Self Diagnosis > Picture Test
4. Perform a cold boot by holding the power button on your remote for about 10 seconds
5. Ensure your TV has the latest software installed: Settings > Support > Software Update
If the issue continues after these steps, the TV may require service. For further assistance, please contact Samsung Support at 1-800-SAMSUNG, 8AM – 12AM EST, 7 days a week. LiveChat and additional support resources are also available through the Support link on our website.

Posted .Hi PatrickM,
Thank you for sharing your experience. Buffering during streaming is typically related to internet speed or signal strength. This can happen when your connection isn’t able to deliver data quickly enough for smooth playback.
We recommend the following steps to help improve streaming performance:
1. Use a 5GHz Wi-Fi connection, if available
2. Try a wired LAN connection for more stability
3. Reposition your router to minimize obstacles between it and the TV
4. Make sure your TV is running the latest firmware (Settings > Support > Software Update)
5. Run Device Care to optimize performance: Home > left directional key > Settings > Support > Device Care > Start Device Care
If buffering continues, you may want to contact your internet service provider to check your current speed or explore upgrade options.
If we can assist further, please call us at 1-800-SAMSUNG (8AM – 12AM EST, 7 days a week), or connect with a LiveChat agent by selecting ‘Support’ on our website.
