When my Jungle Lord sits in attract mode for a while it eventually freezes up, all displays go blank, only general illumination works and it keeps keeps playing the elephant sound over and over again.
Power cycling the game and removing the batteries does not help. The only way I've found to get the game to boot correctly is to remove and replace a ROM chip on the CPU board.
So far I've removed and cleaned IC14 and IC17 but the game will still lock up after sitting in attract mode for a while.
The game works perfect when it's not frozen. What would cause this problem?
