The most frustrating thing when you are trying to repair something is not knowing how to get it open. I do a lot of TV repairs and this one can be quite frustrating if you don't know this simple trick as no matter which tool you use you just can't pry it open, at least not without causing damage. After searching on the internet for this particular model I stumbled upon a lot of people asking for help on how to open it, when I finally found a service manual for a similar model and successfully opened it I decided to record this quick video which I believe will be useful for many technicians/hobbyists out there.

Tools that make TV repair much easier/safer/faster:
*******************************************************

LCD lifting tools + magnetic supports (watch the video on the listing to understand how these tools are used, these make the repairs much safer and easier, I recommend the option "RST2 with Supports")

High voltage LED tester (great to test entire LED strips or just single LEDs as it automatically adjusts the voltage/current, also useful to test zener diodes)

Hot plate (makes replacing LEDs much faster and safer than using the hot air station. Because it uses a PTC element it automatically regulates the temperature)

Assortment of TV backlight LEDs (useful to get started)

Lenses (from time to time I get a TV that has previously been "repaired" by another shop that instead of replacing the faulty LEDs just removed the lenses and jumped the LED pads with a solder blob, this means I can't properly repair if I don't have replacement lenses)
