Help: CreatiVision not working after cartridge polarity reversal
Posted: Tue Apr 28, 2026 7:23 am
Hello everyone. Due to a series of lapses in attention, I inserted the multiROM cartridge into the CreatiVision the wrong way around 
. Of course, now there’s a problem! Has anyone had similar experiences? So far, I’ve found the 7805 burned out. There’s a short circuit on the GND line of the 7805, where a capacitor is connected (but when removed from the board, it tests as good).
