The #SEGA #MultiMega repair log of SN: Y001983. This poor unit has been with me for quite some time due to a lack of references or working systems to compare against until this year.
Also it has been previously professionally repaired by another party. So, it turns on and play games; where's the issue?

Operation is somewhat haphazard at best. We're missing some audio effects, 6 button controllers do not work in 2P and are erratic for 1P, noise during operation in audio & video and CD games work intermittently after ten minutes

This is a poor #PCEngine DUO that was sent to me for the possibility of undoing the death knell that had already been sounded. It had been previously looked at by other people who solder.

No short detected, powers up ok but no video output via composite video.
Let's have a look. Jesus Christ.
