Scared Stiff crate sound effect stuck in a loop on boot
My Bally Scared Stiff has developed a bizarre sound issue. When I power up the game, the crate/coffin banging sound effect starts playing and just loops endlessly. It never stops — it just keeps playing the same banging sound over and over. The background music doesn't start, no other sounds play, just this one looping sound effect.
The game boots up visually on the DMD and seems to go through its normal startup sequence. If I start a game, it plays but with this constant banging sound drowning everything out. No voice callouts from Elvira, no music — just the endless looping bang.
I've tried turning the game off and on multiple times. Sometimes it boots normally and everything is fine, but about 7 out of 10 power-ups result in this looping sound issue. When it does boot correctly, the sound works perfectly for the entire session.

This intermittent sound loop on boot is a classic symptom of failing hardware on the DCS (Digital Compressed Sound) board used in Scared Stiff and other mid-90s Bally/Williams games. The DCS board uses DRAM chips to load and decompress audio data from the sound ROMs during power-up. If one of the DRAM chips has an intermittent failure, the audio data loads incorrectly and the sound processor gets stuck in a loop playing corrupted data.
The first thing to try is reseating the DRAM chips and sound ROMs on the DCS board. Power down the game, locate the DCS sound board in the backbox, and carefully remove and reseat each socketed IC chip, paying special attention to the four DRAM chips (typically 4164 or 41464 type). Corrosion on the IC legs or in the sockets causes intermittent contact, which explains why it sometimes boots fine and sometimes doesn't. Clean the IC legs with DeoxIT and a soft eraser. If any of the IC sockets look corroded or have loose contacts, replace the sockets entirely — machine-pin IC sockets are available at Marco Specialties.
If reseating doesn't resolve the issue, one or more of the DRAM chips may need replacement. You can test by swapping DRAM chips between positions to see if the fault follows a specific chip. Replacement DRAM chips and DCS board components are available at Pinball Life. As a last resort, you may also want to check the sound ROM chips themselves — burn a fresh set from verified ROM images and see if the problem persists. Some owners have had success with aftermarket DCS sound board replacements that use modern components and eliminate the aging DRAM reliability issues.
