    3 Pin Relay Wiring?

    Actually the "coil" section of the relay goes in series with the run winding and monitors the current there during start. A common (one terminal of the relay coil) then switches the start circuit either in or out depending on the aforementioned current via the remaining terminal. Determining...

    That's what the contrast does. Doesn't mean the data is displayed from the LCD scan mechanism.

    Typewriter LCD display repair

    It's an LCD fault. If you look at the display photo in the first photo you'll see the same scan lines are missing in all. Anyhow, I'll leave you to it.

    Tantalum capacitors

    Show a photo of what you have...clear and close up showing all markings is the best. Note that it is uncommon for a tantalum to swell, they usually blow their top. The main check would be 475 for 4.7uF and the voltage at 10v or higher. Either way, Aliexpress have both...

    How to test this 24v 13" Worx Mower

    The Worx mowers use brushless motors with 2 x 40v batteries, most likely lithium or LiPo. So therefore brushless motor controller and not much point poking around trying to measure resistance with a multimeter.
