AC Question

I was in a rush and my phone was completely dead. i saw my brother using this method to charge his phone because his port was broken. i tried it but then my tv turned off. ( i used my TV as an adapter) i stopped trying to use it because it got really hot. when i got to work and used my coworkers charger it was the normal battery charging sign but it had a yellow lightening bolt. i don't know what this means or what i did to my phone but its not charging. what do i do?
when it was plugged up it turned on then died in like a sec. it said i didnt have an sims card. did i damage my sims card too? but i dont know what to do. please help
