I wont get into how I came to purchase this but,..... with suspicions, I ordered this tool to comfirm and to otherwise learn more otherwise on many LED applications. Look at the good price of it, besides replacement LED. I now have an almost new TV lol it works it works it works, great probes but wish the box module was a little more sturdy.I do recommend otherwise ### ⭐⭐⭐⭐⭐ Works as described *by A***N on June 2, 2021* I used this to test the blue light circuits on a tv that I took apart. It did the job. I discovered that the lights were working and that another part of the tv needed replaced. Unfortunately, this is all I can use it for, but at least I know my lights work. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/173309938-led-tester-multipurpose-tester-for-led-lamp-tv-backlight-constant](https://www.desertcart.co.uk/products/173309938-led-tester-multipurpose-tester-for-led-lamp-tv-backlight-constant) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-19*
