True arcade monitor burn-in on a CRT is usually permanent phosphor wear, not a setting problem you can erase. You can sometimes make it less obvious, but in most cases you cannot fully fix it in place without replacing the tube or the whole monitor assembly. If your cabinet has been converted to an LCD or OLED panel, the issue may be image retention instead, which has a different set of fixes.

That distinction matters because a lot of advice gets mixed together. The fastest safe checks are simple: identify the display type, lower brightness, test with varied content, and decide whether you are dealing with something you can live with, something you can hide, or a screen that needs real repair. If you’re restoring older cabinets like Galaga vs Galaxian, knowing what kind of display you actually have saves a lot of wasted effort.

For modern panels, Sony’s support guidance on image retention is a useful reminder that pixel shift and panel-maintenance features can help with temporary retention, but they do not repair worn CRT phosphor: image retention guidance.

What arcade monitor burn-in actually is

On a CRT arcade monitor, burn-in happens when the same parts of the screen are driven harder for long periods. Bright score areas, life counters, health bars, and attract-mode logos can wear the phosphor unevenly. Players often notice it most on dark screens, where the old image is still visible as a faint outline.

That is different from temporary image retention on LCD or OLED panels. Retention can fade, especially after the display is turned off or after varied content has been shown. CRT burn-in is physical wear, so the rules are different.

Community reports from arcade restorers also point to the same pattern: static HUD elements and long-running attract screens tend to leave the worst marks, especially on cabinets that were run at high brightness for years. That is why a worn score box can show up long after the game itself looks fine.

Quick checks before you replace anything

Confirm the display type. If it is a CRT tube, treat burn-in as wear. If it is LCD or OLED, you may be dealing with retention instead.
Look at a black screen. A permanent ghost image that stays visible usually points to burn-in. If the mark fades after the cabinet sits off for a while, that leans more toward temporary retention.
Check for color blotches. If the problem is more about weird color patches, magnetization or purity issues may be involved. That is not the same as burn-in.
Watch overall brightness. A very dim or uneven tube may be worn out in more ways than one, which changes whether repair is worth it.

One important note: degaussing can help with magnetic discoloration on a CRT, but it does not repair burn-in. It fixes a different problem.

Fastest safe fixes to try first

Lower brightness and contrast. This will not restore a worn tube, but it can make burn-in less distracting and reduce further wear.
Use varied content. If the cabinet is a multi-game build or has a PC-based setup, looping full-screen colorful content can help temporary retention on LCD or OLED panels. On a true CRT, it may make the image easier to judge, but it will not reverse phosphor wear.
Turn the display off normally. For modern LCD/OLED conversions, leaving the panel off overnight or longer can help retention fade. That is not a cure for CRT burn-in, but it is a good way to see whether you are dealing with a temporary issue.
Use the panel’s built-in maintenance tools if it has them. Pixel shift and panel-refresh features can help some modern displays. They are useful on LCD/OLED conversions, not on a CRT tube.
Check the cabinet glass or bezel. Sometimes what looks like burn-in is just dirt, haze, or a scratched overlay making the image look worse than it really is.

If you have a custom cabinet that can run videos, a colorful moving test pattern is a better check than a static white screen. The old white-screen trick is not a real burn-in repair for CRTs, and running a tube at maximum brightness for long periods can shorten its life.

What actually changes the outcome

What you see	Likely cause	Best next step
Faint ghost image only visible on dark screens	Mild CRT burn-in	Lower brightness, live with it, or hide it with tinted glass
Image fades after the cabinet is turned off	Temporary retention on LCD/OLED	Use normal panel maintenance features, pixel shift, and varied content
Blotchy color or uneven purity	Magnetization or convergence issue	Try degaussing or proper CRT service; do not treat it like burn-in
Heavy ghosting, dim picture, or obvious wear in gameplay	Severe CRT phosphor wear	Consider tube replacement or a full monitor swap
Burn is visible but not distracting	Old but usable tube	Leave it alone if the cabinet still plays well

Low-risk ways to make burn-in less noticeable

Reduce brightness first. This is the simplest way to make worn areas stand out less.
Use smoked glass or tinted plexi. Many collectors use tint to soften the look of an old tube. It does not fix the burn, but it can keep the cabinet looking cleaner when it is off and reduce how obvious the wear is when it is on.
Keep the screen moving. Static attract-mode screens and long pause menus are rough on old displays. A moving image distributes wear better than a fixed HUD.
Separate CRT advice from modern-panel advice. If your arcade build has been converted, Sony’s retention and panel-refresh guidance applies to the LCD/OLED part of the system, not to a worn CRT tube.

On community forums, the usual advice for mild burn-in is not “repair” so much as “hide or live with it.” That is often the practical answer when the cabinet still plays well and the wear is only noticeable on black screens.

When tube replacement or a full monitor swap makes sense

If the burn-in is deep, the tube is dim, or the cabinet has other display problems at the same time, replacement often makes more sense than chasing cosmetic fixes. That is especially true if the monitor is already unstable, has geometry issues, or needs more work than the cabinet is worth.

iFixit’s CRT troubleshooting notes make the same basic point: older CRTs wear out, and sometimes the sensible answer is repair only if the tube is otherwise worth saving: CRT display troubleshooting.

A good rule of thumb is this: if the burn is mild and gameplay is still enjoyable, you can probably keep using the monitor. If the tube is heavily worn or the picture is collapsing in more than one way, replacement starts looking better than repair.

Tube-swap safety and compatibility caveats

A donor tube swap can solve burn-in, but it is not a casual plug-and-play repair. The chassis, yoke, rings, and tube all have to be compatible, and the setup often needs careful alignment after the swap. Arcade restorers also warn that you should mark the yoke ring positions before moving anything, because small adjustments can change the picture a lot.

This is also where safety matters. CRT monitors carry high voltage even after they are turned off. If you are not comfortable working around that, or you do not already know how to discharge and service a CRT safely, this is a job for an experienced technician.

If you are already deep into a cabinet restoration, that same caution applies to other classic machines too, including a Galaga and Galaxian differences style repair where parts matching matters more than people expect.

What not to do

Do not assume degaussing will fix burn-in. It will not.
Do not run a full white screen at max brightness for hours. That is not a real cure for CRT burn-in and can shorten tube life.
Do not confuse LCD/OLED retention with CRT wear. The fix depends on the display type.
Do not force a tube swap without matching the right parts. Compatibility is model-specific and mistakes can create new problems.

How to prevent burn-in on future arcade setups

Keep brightness only as high as you need it.
Avoid leaving static score screens or pause menus up for long stretches.
Use attract modes that move around instead of freezing one image in place.
Turn off the cabinet when it is not being used.
If you are building a multi-game cabinet, use screen savers and any pixel-shift or panel-maintenance features available on the display.

If you are starting a fresh restore, think in terms of display preservation from day one. That matters on classics like Galaga vs Galaxian, where the cabinet can still be enjoyable even if the monitor is old, as long as the wear is kept under control.

For a lot of arcade cabinets, the real goal is not to make every mark disappear. It is to decide whether the picture is still good enough to enjoy, whether it can be hidden well enough to live with, or whether the tube has reached the point where replacement is the honest fix.

Frequently asked questions

Can arcade monitor burn-in be fully fixed?

On a CRT, usually no. True burn-in is phosphor wear, so you can reduce how noticeable it is, but you normally cannot reverse it without replacing the tube or the whole monitor.

Does degaussing fix burn-in?

No. Degaussing is for magnetic discoloration and purity issues. It does not restore worn phosphor.

Will pixel shift help my arcade monitor?

Only if the cabinet uses an LCD or OLED panel that supports that feature. Pixel shift can help reduce retention or uneven wear on modern displays, but it does not repair a CRT.

Is a white screen a good burn-in fix?

Not for CRT burn-in. It is a myth that gets repeated a lot, but it will not restore worn phosphor and may make wear worse if you push the brightness too hard.

When should I replace the monitor instead of trying to fix it?

If the burn is severe, the tube is dim, or the picture has other major problems like geometry or color issues, replacement is usually the better move.
