Message: [QUOTE="RETRO-VETRO, post: 342688, member: 95464"] That oscillation is normal to an extent. The original DMG screen uses a passive-matrix reflective LCD that refreshes line by line, which can cause flicker or rolling bars when filmed, similar to what happens with CRTs but for different reasons. However, if you’re seeing that effect clearly with your eyes (not just through a camera), it could indicate aging components or voltage instability. Old capacitors are a common culprit. If both of your units show the same behavior, it might just be how your lighting interacts with the screen, especially under fluorescent or LED lights that flicker at 50/60 Hz. But if the effect is persistent and distracting during normal play, a recap could help. It’s also worth checking the contrast wheel and making sure the LCD ribbon cable is seated properly. TL;DR: A little flicker is expected. Noticeable oscillation in person might mean it’s time for maintenance. [/QUOTE]
