When buying a pinball machine, ask the seller to power it on, enter diagnostics, show you the battery area, and point out every missing or nonworking part before you talk price. Those four checks reveal most of the expensive problems buyers miss.
The right questions also depend on what kind of machine you want. A project game, a player-ready used game, and a brand-new machine all carry different trade-offs, and a table that looks fine from across the room can still hide board damage, water exposure, or playfield wear that changes the deal completely. If you want a rough sense of how asking prices are usually framed, compare the listing to current pinball machine prices and, if needed, check broader pinball machine values before you commit.
This article keeps the focus on the questions that matter most: what to inspect, what to ask the seller, which wear is normal, which damage is expensive, and when it makes more sense to walk away.
The most important questions to ask first
If you only have a few minutes with the machine, start with the checks that tell you whether it is healthy enough to buy at all.
| Question | Why it matters | Red flag |
|---|---|---|
| Does it boot and enter attract mode? | Proves the game powers up and is at least basically alive. | No boot, reboot loop, dead displays, or constant resets. |
| Are there error messages or a credit dot? | Diagnostics often point to failing switches, switches stuck open/closed, or board issues. | The seller refuses to open diagnostics or says errors are “normal” without explaining them. |
| Is the battery area clean? | Old batteries can leak and damage the CPU board and nearby connectors. | White crust, green residue, burnt traces, or a repaired area that looks rushed. |
| What parts are missing or broken? | Missing ramps, plastics, toys, and backglass parts can be expensive or hard to replace. | “Just cosmetic” claims when the missing parts affect gameplay or are no longer easy to source. |
| How will it be moved? | Transport prep is part of the real cost and risk. | No plan for legs, head, stairs, narrow doors, or safe loading. |
Electrical faults are where many first-time buyers get burned. A machine can look clean and still have board damage, hacked wiring, bad connectors, or a battery leak that spread farther than it first appears.
Ask about the battery and board history
Older solid-state and DMD-era machines may have battery-backed boards, so ask these questions directly:
- Has the battery ever leaked?
- Has the CPU board been repaired or replaced?
- Were the connectors ever repinned or reflowed?
- Has anything been hacked or bypassed to keep the game running?
A clean battery compartment is good news. A machine with obvious leakage is not automatically a hard no, but it should be priced like a repair project unless the seller can prove the damage was properly cleaned and the boards tested afterward. Community experience consistently treats battery corrosion as one of the biggest hidden cost risks.
Ask to see diagnostics, not just gameplay
Gameplay alone does not tell you enough. Ask the seller to open test menus and confirm that switches, coils, lamps, display functions, and sound all work. Experienced buyers often use this moment to look for stuck switches, weak flippers, dead coils, and problems that only appear after the machine warms up.
If you are comparing an older machine to a modern one, remember that newer games often feel easier to verify but can be harder to source parts for if the exact title has niche components. In that situation, title-specific parts research matters just as much as the cabinet condition.
Questions about playfield wear and missing parts
Cosmetic wear is not the same thing as structural damage. A scratched cabinet can be annoying, but it usually matters less than playfield wear, wood damage, or water exposure.
What wear is acceptable?
Normal wear items include rubbers, flippers, bulbs, coils, drop-target faces, switches, and general dirt. Those are common maintenance items on most machines, especially older ones. A game can still be a good buy if the seller has already accounted for those replacement costs.
What damage is expensive?
The bigger problems are the ones that affect the playfield structure or electronics:
- Wood wear or planking in high-impact areas
- Insert lifting or cracked inserts
- Water damage, mold, or swelling in the cabinet
- Burnt connectors or heat-damaged wiring
- Corroded boards or battery damage
- Missing ramps, toys, plastics, translites, or backglasses that are hard to replace
Community reports from buyers and techs consistently point to playfield wear around inserts, scoop holes, ramp exits, shooter lanes, and other high-traffic spots. If the wear has gone through the artwork and into the wood, the value drops fast.
For a deeper look at how condition changes what a game is worth, the breakdown in what my pinball machine is worth is useful when you are comparing a clean example to a project machine.
Questions about service history and what has already been repaired
A seller’s repair history tells you a lot about what you are really buying. Ask these questions in plain language:
- When was the last time the machine was serviced or shopped?
- What parts were replaced recently?
- Has the game had board work, connector work, or a battery-area repair?
- Are there any known intermittent problems?
- Which parts are missing from the game, even if it still plays?
This is also where exact title research helps. Some machines have known board weaknesses, unobtainable plastics, difficult-to-find ramps, or scarce backglass parts. If the seller cannot tell you what has already been repaired, you should assume there may be more hidden work ahead.
Questions about transport, stairs, and setup
Transport is part of the buying decision, not an afterthought. A machine that seems like a bargain can become a hassle if it has to go up narrow stairs, through a tight door, or down a basement turn that barely fits the cabinet.
Ask these transport questions before you agree to buy
- Does the head fold down?
- Do the legs need to come off for transport?
- Can the seller help prep the game safely?
- Will the balls be removed before moving?
- Are photos available before any cables or parts are disconnected?
Older or larger machines can be awkward and heavy, and the head box is often the part that causes the most trouble in a move. If you have a choice between shipping and local pickup, local pickup is usually easier for a first-time buyer because you can test the game and avoid shipping damage.
If you are deciding between a real machine and a cabinet-style alternative because space is tight, virtual pinball vs real pinball is worth comparing before you commit to a heavy pickup you may regret later.
When the seller’s answers should make you walk away
Some problems are negotiable. Others are red flags.
Walk away or reduce your offer sharply if you find any of these:
- Obvious battery leakage with board damage
- Water damage, mold, or cabinet swelling
- Hacked wiring that the seller cannot explain
- Burnt connectors or overheated power-supply areas
- Major playfield wear into bare wood without a proper discount
- Missing parts that are known to be scarce or expensive
- A seller who will not power the game on or refuses diagnostics
Battery corrosion cleanup is sometimes fixable, but it is a repair path, not a free pass. If the machine is already cheap and you are comfortable with electronics work, a damaged game can still make sense. If you want a reliable player with minimal hassle, it usually does not.
Questions to ask based on the type of machine
For a home buyer
Ask how much upkeep you are realistically willing to handle. If you want a low-stress machine, a cleaner used game or a newer machine is often easier than a project pin. If you enjoy tinkering, an older solid-state or EM game can be satisfying, but it will reward owners who like maintenance.
For a route or commercial setup
If the game is going into a public location, ask more about uptime, parts availability, service access, and how often the machine has needed repairs. A commercial setting is much harder on flippers, switches, rubbers, and coils than a home game room. A new machine can make sense here because downtime is more expensive than the purchase price alone.
For EM, solid-state, and DMD-era games
EM machines are simpler in some ways but can demand more mechanical attention. Solid-state games add electronics and board concerns. DMD-era machines sit in the middle ground for many buyers, but they can still have aging power supplies, display issues, and battery-related damage. The best choice is not the fanciest one; it is the one you can inspect, maintain, and source parts for.
First-time buyer checklist
- Power it on and watch the full startup cycle.
- Open diagnostics and check for errors.
- Inspect the battery area for leakage or corrosion.
- Look closely at shooter lanes, ramps, inserts, and scoop areas.
- Check for missing plastics, toys, and backbox parts.
- Ask what has already been repaired and who did the work.
- Confirm how the machine will be moved, loaded, and set up.
- Compare the asking price with similar current listings and the machine’s overall condition.
FAQ
What are the first questions I should ask when buying a pinball machine?
Ask whether it boots, whether diagnostics show any errors, whether the battery area is clean, what parts are missing, and how the game will be transported. Those questions catch most of the expensive problems before you hand over money.
Is battery corrosion always a deal-breaker?
No, but it is a serious warning sign. Light corrosion may be repairable, but heavy leakage can damage boards and connectors. If the seller cannot explain the repair clearly, assume there may be more hidden work.
What matters more: cabinet scratches or playfield wear?
Playfield wear usually matters more because it affects gameplay and value. Cabinet scratches are often cosmetic, while wood damage, insert lifting, or wear through the artwork can become expensive quickly.
Should I buy a new pinball machine or a used one?
Buy new if you want the least uncertainty and are willing to pay more. Buy used if you want a wider selection and are comfortable evaluating wear, repairs, and parts availability. For many first-time buyers, a clean used machine from a local seller is the best balance.
In the end, the smartest questions are the ones that tell you how the machine plays, how it was treated, and what it will cost to keep running. If the seller can answer those clearly, you are in much better shape than if you only judge the game by the artwork and the lights.
