Need help with my Haibi 30 slot machine

[Turbocharge]

When I first got the machine, it worked fine. Then a week later as I'm trying to sell it, the buyer put a quarter through the back of the door since the coin slot has been sealed and now when i go to turn it on it wont work correctly. The reels dont light up and the "payment setting" light on the main board is flickering. I tried to do a reset but the lever to spin the reels is the reset button and it wont work. I've gotten it to work one round at a time, but after one round I have to turn it off and back on or else it just shuts off. I dont know what to do or how to fix it
