I bought this dummy battery https/www.amazon.com/dp/B07JJ2KCWT/ref=cm_sw_r_cp_apa_i_8pCwCbCH17P3V for my Nikon D5300 camera. I plugged into the wall power using a DC coupler and a 9V DC power supply. It was working and I was quickly testing out taking pictures for 2 minutes tops. I turned it off manually and then tried to turn it on again but it wouldn't. It's been almost a day since that now and it still won't turn on even with the battery that came with the camera. Is my camera broken? If so what are my options?
