Hi I know everyone tells me not to use a switching power supplies on these type of games because they cause a hum in audio. I have four games know that these have stoped working all together or are what I think is causing me sound problems.
1. satans hollow- not showing any sign of life at all boards tested in another good power supply and working.
2. Demolition derby- was working with a loud hum now also dead no sigs of life tested with another power supply and working.
3. Tron- was working then went to garbage on the screen tested with good power supply and working fine.
4. Root beer Tapper- plays fine but audio not working. I have not tested with different power supply yet.
So does anybody rebuild these old MCR or what is my best option?
