My Android LG phone won't turn on or charge?

I have an LG q7 plus that has a non removable battery. I had it on the charger and I took it off and set it on the counter. It was like 63% charged. I went to get it and turn it back on and it wouldn't turn on and won't charge. I tried to soft/hard reset and nothing worked . How can I fix this? I even tried doctor fone or whatever that recover thing is but it only does galaxy phones. I can't do the debugging on the phone because it will not turn back on. What can I do to fix it or is it just done for?
