Just dead

So 2 days ago my Shield TV 2017 model died it seems. Day before I plugged it into LG CX and Shield started as usual but UI was so tiny. Changed resolution to 4k 60hz and it immediately shut down... and never came back. It was nice 5+ years... Seems so weird it would crash just because I changed something in OS. Maybe power adapter also failed? Do not know. Oh well.

Anyone knows if there is anything I can do? Apart from soldering some USBC adapter etc.
