What causes burn-in on arcade CRT monitors?

Burn-in occurs when static images are displayed for extended periods, causing the phosphor coating inside the CRT to wear unevenly. High-contrast elements like score displays, health bars, and static logos are most likely to cause permanent ghosting on vintage arcade monitors.

How long can I safely leave my arcade machine on?

For cabinets with original CRT monitors, limit continuous use to 4-6 hours with breaks in between. If you need to step away for more than 15 minutes, either engage a screen saver, switch to a burn-in prevention demo mode, or power down the monitor to protect the phosphors from uneven wear.

Can screen burn-in on an arcade CRT be reversed?

Minor burn-in can sometimes be reduced by displaying a pure white screen for short periods or using specialized burn-in reversal videos, but severe cases are usually permanent. Prevention is always the best strategy—use screen savers, rotate games, and avoid displaying static images for extended periods.

Prevent Burn-In: Screen Saver Tips for Classic Arcade CRT Monitors

CRT burn-in can destroy a classic arcade monitor's value and playability in months. This guide covers proven screen saver techniques — from built-in settings to aftermarket hardware — that keep phosphor screens healthy without sacrificing authentic gameplay.

What causes CRT burn-in on arcade monitors?

Burn-in happens when static images linger too long, etching ghost patterns into the phosphor coating. Score displays, health bars, and attract mode screens are repeat offenders. The damage is permanent — once burned, the screen shows faint shadows even when powered off. That said, not all arcade tubes are equally vulnerable. Older vector monitors (think Asteroids or Battlezone) resist burn-in better than raster tubes, though neither is immune.

Do original arcade PCBs have burn-in protection?

Most do — but the effectiveness varies wildly by manufacturer and era. Here's how major manufacturers handled screen protection:

Manufacturer	Protection Type	Reliability
Atari (classic era)	Attract mode cycling	Moderate — static elements remain
Capcom (CPS series)	Demo mode + screen dimming	Good — frequent scene changes
Namco (System 1/2)	Attract loop with motion	Moderate — logo screens linger
Sega (Model 2/3)	Full demo attract sequences	Excellent — minimal static time

The catch? Even "good" protection assumes the machine gets powered off periodically. A Street Fighter II cabinet running 18 hours daily in a pizza shop will develop burn-in regardless of Capcom's best intentions.

What screen saver hardware works for arcade CRTs?

Aftermarket solutions fill the gaps where PCB software falls short. The Arcade SD multi-game board includes configurable attract mode timers that force screen blanking after idle periods. For purists keeping original hardware, the Twisted Quarter Screen Saver Board offers a simpler fix — it cuts video signal entirely when no button presses occur for a set interval.

Worth noting: some collectors use Ultimarc's Video DAC solutions with Raspberry Pi setups to cycle randomized attract sequences. It's not authentic — but it saves irreplaceable tubes. You'll want to balance preservation goals with your cabinet's historical integrity.

Set the timer conservatively. Five minutes of inactivity triggers blanking on most commercial units — your home collection can afford the same caution. Rotate games periodically if you own multiple boards. A Pac-Man machine showing the same maze layout for six months straight? That's asking for trouble — even if the ghosts keep moving.
