LCD tvs from 2012 and 2022 just went kaput for no reason.
Most likely bad capacitors. The https://en.wikipedia.org/wiki/Capacitor_plague https://en.wikipedia.org/wiki/Capacitor_plague may have passed, but electrolytic capacitors are still the major life-limiting component in electronics.
- londons_explore 11mo agoMLCC's look ready to take over nearly all uses of electrolytics. They still degrade with time, but in a very predictable way. That makes it possible to build a version of your design with all capacitors '50 year aged' and check it still works. Sadly no engineering firm I know does this, despite it being very cheap and easy to do.
- DoesntMatter22 11mo agoLooks like that plague stopped in 2007? I have a 8 year old LCD that died out of nowhere as well, So I'm guessing wouldn't be affected by this. Could still be a capacitor issue though
