hey everyone extremely new to the hobby here and am picking up my very first cabinet for 25 bucks thursday april 8th 2021 as you can probably tell from the title of the post it is a atari battlezone i dont have a picture right now but it appears to be in pretty good condition so im fairly confident i can get it to work what im wondering is what should i look for in terms of bringing it back to life? the seller thinks its the power supply and possibly the monitor? how easy is it to switch out the power supply also thinking i should maybe check the fuses i do not have a multimeter or any sort of tools is any of that required before i go poking around all willy nilly? any help is appreciated as i am a huge noob and dont wanna kill myself over something silly
