Fixing Samsung UE40D5720RS Boot Loop with a Simple Ice Cube Hack

If you have a Samsung Smart TV (model UE40D5720RS) stuck in an endless boot loop — showing HDMI or the Smart TV logo and then restarting — you're not alone. This issue is often caused by NAND flash memory degradation, which prevents the firmware from being read correctly at boot.

Quick Fix That Actually Works

Place an ice cube wrapped in cling film directly over the main NAND flash chip (labeled IC1300) on the TV’s mainboard before powering it on. Cooling the chip stabilizes its read operations just enough to let the TV boot normally.

	Generate Image Sitemap for a Single HTML Page

	This script reads an HTML file, extracts all the image URLs from the <img> tags, and generates an XML sitemap compliant with Google's image sitemap protocol. The generated sitemap can help improve the visibility of images in search engines.

	Usage:
	- Ensure you have the 'beautifulsoup4' package installed: `pip install beautifulsoup4`
	- Set the `html_file` variable to the path of your HTML file.
	- Set the `page_url` variable to the URL of the page where the images are located.
	- Run the script to generate 'sitemap.xml' containing the image sitemap.
