Hi Sn,<br /><br />We appreciate your review of Samsung&#39;s QN70FD. To best assist with parts missing from your TV&#39;s stand, we suggest reaching out to Sam&#39;s Club for assistance with this.<br /><br />Regarding your TV&#39;s language - it sounds like the initial language selection may have been bypassed during setup. To change it, go to: Home &gt; left directional key &gt; Settings &gt; All Settings &gt; General &amp; Privacy &gt; Language, and select your preferred language from the available options.<br /><br />For optimal performance, please ensure your TV is running the latest firmware. You can check this by going to: Home &gt; left directional key &gt; Settings &gt; Support &gt; Software Update<br /><br />To further optimize performance, try running Device Care, which checks memory, clears unused cached data, and closes background apps: Home &gt; left directional key &gt; Settings &gt; Support &gt; Device Care &gt; Start Device Care<br /><br />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 &gt; All Settings &gt; General &amp; Privacy &gt; Power and Energy Saving, then turn off Brightness Optimization, Energy Saving Solution, Motion Lighting, and/or Contrast Enhancer.<br /><br />If the image still isn’t meeting your expectations, select a Picture Mode that best fits your environment: Home &gt; Home &gt; left directional key &gt; Settings &gt; All Settings &gt; Picture &gt; Picture Mode<br />1. Standard – Default mode for general viewing<br />2. Dynamic – Brighter and clearer in well-lit rooms<br />3. Eco – Optimized for energy saving<br />4. Movie – Best for watching in dark environments<br />5.
