Hi Dray, Thank you for sharing your review. Your TV Works With Alexa, meaning you’ll need to connect a standalone Alexa device such as an Echo speaker, to control compatible smart home devices and some experiences on your TV. Here are the steps: 1. Download both the Amazon Alexa and Samsung SmartThings apps, if you don't already have them. Both are available for iOS or Android devices. 2. Make sure your Alexa device and TV are both connected to the same Wi-Fi network. 3. Your TV must be enabled within the SmartThings app. If not, make sure you are signed in with your Samsung account on the TV: Settings > All Settings > Samsung Account 4. Log in to the SmartThings app with the same Samsung account. Tap Devices, and if your TV isn’t already shown, tap + to add it to the app. 5. In the Alexa app, enable the SmartThings skill and sign into your Samsung account. This will automatically connect your Samsung TV to Alexa and let you use voice commands to control your television.

Hi Bonbon, Thank you for sharing your experience with Samsung’s U7900F. If your TV is displaying lines 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.
