TV repair training and tools

@kristopherw depends how deep into you want to go with these repairs. For the beginning I’d stick with just the basic tools. Couple of good multimeters, LED backlight testers are a must. Oscilloscope is optional but nice to have. Of course good screwdrivers, soldering stations etc.,irons always come in handy. As for the “education” part stick with AC/DC circuitry, boost circuitry, power supply technology, backlight technology (CCFL, LED, OLED, QLED etc.) and of course the LCD display itself. Again, all of this depends how deep into you want to go into it and what your long term plan is.

Main issue you are going to run into is the lack of support from the manufacturers. Service manuals that are needed will not be made available to you. Stay away from brands like VIZIO (hodgepodge of parts from all over. Inconsistent quality and poor support), TOSHIBA ( black helicopter company that will hunt you down with their attorneys and force you into submission if you even try to service one of their TV’s. That company should have been gone long time ago). Hisense, TCL etc have poor support and are difficult to repair since once more service manuals are almost non-existent for the normal service person.

The independent repair industry has been dealing with this for a long time. Some light reading on here https://www.ifixit.com/Right-to-Repair/I... and I strongly recommend you looking into this https://repair.org/electronics

Just my 2 cents from my experiences as a hobbyist.
