Adding value to your pinball machine: the simple repairs that raise its worth

Which repairs really drive up the value of an old pinball machine? The short answer: the ones that make it start up and play reliably. A dead machine gets sold off cheap; the same machine that lights up, keeps score and strings games together simply moves into another category. After that come a handful of low-cost cosmetic and mechanical touch-ups that improve the first impression — provided you don't fall into over-restoration, which can actually lower the value.

This guide runs through nine classic weak points of a vintage pinball machine (Bally, Gottlieb, Williams, Stern from 1977-1989). For each one: the symptom, several options from budget DIY to professional work, an estimated cost and an honest assessment of the added value. All prices were recorded in July 2026; dollar amounts are converted at the 22 July 2026 rate (1 $ ≈ 0.88 €, source at the end of the article) and remain indicative, excluding shipping and any import duties.

Full disclosure: Pinballs Store designs and sells replacement electronic boards (FPGA) and offers board repair. We sell neither LEDs, nor legs, nor stencils, nor backglasses, nor displays: for those items, we point you towards genuine specialist suppliers. A board fixes the electronics, not the mechanics or the looks.

1. Dead electronics / leaked battery

The weak point: this is the number-one value killer. On most solid-state pinball machines, a 3.6 V battery or three AA cells are mounted on the MPU board to save the settings. As it leaks, the battery eats away at the traces and components: the machine no longer starts. A buyer who reads "won't power on" or sees corrosion immediately halves their offer — when they don't walk away altogether. Our article Leaking battery on a pinball machine details the damage.

The options:

• Have the original board repaired — battery replacement, neutralising the corrosion, rebuilding the traces, changing the burnt-out components. Our repair rates: 20 € flat handling fee + 50 €/h of labour + components. Economical when the damage is limited and you want to keep the original electronics.
• A new, battery-free replacement board (our FPGA boards, plug & play — never a leaking battery again). Depending on the machine:
  • Gottlieb System 80/80A/80B: the GottFA80_Plus all-in-one (MPU + driver + sound) at 349 €, or the V2 Full version with integrated sound board at 399 €. To replace just one block: Godri80 driver board at 99 €, Gosof sound board at 129 €, or the Lisy80 (199 €) to diagnose and drive the machine.
  • Williams System 3 to 7: WillFA7 (MPU + driver) at 349 €.
  • Bally / Stern 1977-1985: BallyFA (CPU) at 299 €, BallyDri (power + driver) at 199 €, BallyLa_60 (lamp driver) at 149 €.
  All our boards: 6-month warranty (parts and labour) + 30-day satisfied-or-refunded. To choose between the two routes, see repair or replace a board.

Estimated cost: 20-150 € for a one-off repair; 99-399 € for a new board depending on scope.

Added value: this is THE decisive item, and the strongest argument in this whole guide. A machine that goes from "dead" to "starts up and plays reliably" moves into another price bracket. We can't promise an exact figure — it depends on the model — but the gap between a working pinball machine and a dead one is by far the largest. In the classifieds and on Pinside, a "fully working" game sells faster and is haggled down less than a "won't power on" project. If you do only one thing, do this one. See also the electronics of a pinball machine explained and the repair price guide.

2. Damaged backglass (flaking, peeling)

The weak point: the screen printing of the backglass flaking, blistering or crumbling to dust. It's the first thing the eye lands on; a backglass in tatters weighs down the overall impression and worries the buyer, because the phenomenon is progressive and irreversible if it isn't stopped.

The options:

• Stabilise early flaking yourself. Krylon Triple Thick varnish is the go-to community technique for locking down paint that is starting to lift (careful application, ideally between 13 and 24 °C, sometimes under a smoothed plastic film for 24 h). Two limits to be aware of: it stabilises, it doesn't "repair"; and if the art is already coming off in large patches, it's often too late. Clean very cautiously beforehand, because one wrong move makes everything worse. Cost: ~15-25 € a can.
• A new reproduction backglass. Several serious manufacturers are still active in 2026: Classic Playfield Reproductions (CPR, Canada), repro backglass ~289-315 $ (≈ 255-280 €) — the company is reorganising in 2026 (Mike Purcell stepping down from the presidency, taken over by Kevin Wayte) but is continuing pre-orders across its three lines of playfields / backglasses / plastics; in Europe, you can find them through resellers such as Ministry of Pinball (Netherlands). Shay Arcade Group (United States), a recognised specialist in repro backglasses and plastics for over twenty years. BGResto (United States), backglass restoration/repair and reproductions, on quotation.
• Localised touch-up kits for small missing areas, if you are patient and meticulous.

Estimated cost: 15-25 € (home stabilisation); 255-320 € + shipping for a reproduction backglass.

Added value: high on the visual side — the backglass "makes" the advert photo. A clean backglass puts the machine back into a saleable presentation. An honest caveat: on a common model, the price of a new backglass can represent a large share of the game's value; the operation pays off on sought-after models (or for your own pleasure), less so on a low-value game. In many cases, stabilising an original that is still presentable offers the best value for money.

3. Tired cabinet / paint

The weak point: a scratched, stained, dulled cabinet with worn corners. Nothing "ages" a machine more in photos.

The options:

• The most cost-effective first: a deep clean, a magic eraser on the marks, then localised touch-ups with a marker or paint. Under 20 €, and often striking.
• Stencils to redo the artwork identically: for example Pinball Pimp (United States), premium sets at ~139-189 $ (≈ 122-166 €) + ~80 $ international shipping (~70 €), i.e. about 190-235 € delivered in Europe. This assumes careful sanding, priming and painting.
• A full repaint + decals: a major job, to be reserved for genuinely damaged cabinets.

Estimated cost: 10-20 € (cleaning/touch-ups) to 200-400 €+ (stencils or repaint).

Added value: variable, and this is the item where you need to be careful. A thorough clean always improves the sale. On the other hand, a botched or "too new" repaint can scare off collectors, for whom originality comes first: an honest original cabinet beats an approximate repaint. Only repaint if the cabinet is genuinely degraded and if you are aiming for a clean result.

4. Weak lighting

The weak point: yellowed or burnt-out incandescent bulbs, a dull playfield and backglass that lack punch.

The options:

• Replace a few strategic bulbs with LEDs. At Comet Pinball (United States), the benchmark 2SMD bulb costs 0.69 $ each (≈ 0.60 €); Titan Pinball and PinballBulbs also offer wide ranges.
• A full LED kit per game. PinballBulbs offers game-specific kits (from ~79.99 $, ≈ 70 €); in France, FlipperLED sells complete per-machine kits at around 160 € (free shipping from 50 €).

Tips: on a vintage pinball machine, warm white respects the original atmosphere better than clinical cool white — save the latter for the inserts that need to pop. Watch out for "ghosting" (LEDs that stay faintly lit) on some older matrices: choose non-ghosting LEDs, or add an anti-ghosting board (OCD) if needed.

Estimated cost: 10-30 € (a few key LEDs) to 70-160 € (full kit).

Added value: excellent effect-to-price ratio. Lighting transforms the perception of a machine, in photos as in the flesh, for a few dozen euros. It isn't a "technical" criterion, but a bright advert and a demo that pops sell better.

5. Rubbers and balls

The weak point: hardened, cracked, grey rubbers; pitted or magnetised balls that scratch the playfield and play badly.

The options:

• New balls: a few euros each (standard carbon steel). Change them systematically — a pitted ball damages the playfield every game.
• A complete rubber kit matched to the machine: ~15-50 € depending on the model (Titan, Comet or Pinball Life in the United States; pinball.center in Germany, PU-parts in Europe). Colour choice: original black, white, clear, or premium silicone.

Estimated cost: 5-50 €.

Added value: the best feel-to-price ratio. New rubbers and a new ball immediately restore a game that "responds", noticeable from the very first demo game. It's inexpensive and expected by any knowledgeable buyer. Our maintenance guide details the replacement.

6. Rusty legs / seized levelers

The weak point: legs pitted with rust, seized levelers, damaged bolts. A detail that gives away a machine "left in the cellar".

The options:

• The cheapest: replace the levelers and the bolts. At Marco Specialties (United States): LL2 (2") leveler 1.29 $, LL3 (3") 1.25 $, Williams leg reinforcement plate 8.99 $, bolts ~0.50-1 $ each, protective cups ~10-22 $.
• A set of 4 new legs: 28.5" chrome leg A-19514 at 17.99 $ each (≈ 16 €); grey Bally leg P-4052-8 at 28.99 $ (≈ 26 €, sometimes out of stock — check availability). In Europe, alternatives (pinball.center, etc.) avoid shipping and customs.

Tip: the right leg size depends on the machine — see our complete guide to leg sizes.

Estimated cost: 5-15 € (levelers/bolts) to 65-120 € (set of 4 legs + bolts).

Added value: a good first impression and a machine that stands level. It's a detail, but clean details — tidy legs, a level machine — reassure the buyer about the overall upkeep. Moderate impact, low cost.

7. Worn / dull playfield

The weak point: a grimy, dull playfield with worn clear areas and marked inserts. It's the heart of the game: its condition carries a lot of weight.

The options:

• Cleaning + polishing + protection: Novus 2 (cleaner and fine polish, ~8-9 $ i.e. ≈ 8 € a bottle) then Novus 1 for upkeep, and a protective wax. The result is often spectacular on a merely grimy playfield.
• Mylar removal / touch-ups + clearcoat: a delicate operation. Removing old mylar can tear off the paint; touch-ups and clearcoat are professional work (several hundred euros — an indicative order of magnitude, not a quote). To be reserved for genuinely worn playfields.
• A reproduction playfield (repro playfield): the heavy option. CPR produces repro playfields at around 650-850 $ (≈ 570-745 €, often 600-950 € delivered in Europe including VAT depending on the title). It's a full rebuild.

Estimated cost: ~15 € (Novus + wax) to 600-950 €+ (repro playfield, excluding rebuild).

Added value: cleaning/polishing is one of the very best value-for-money moves there is. Conversely, a repro playfield only pays off on sought-after models: on a common game, the cost of the part plus the rebuild quickly exceeds the machine's value. The "pro" figures above are orders of magnitude, not quotes.

8. Weak displays

The weak point: displays with weak segments, missing digits, a tired plasma. An unreadable score tells the buyer "end-of-life machine".

The options:

• A reconditioned original display: from ~50-65 € for a tested Gottlieb System 1/80 display (reconditioned second-hand).
• LED replacement displays: long supplied by XPin, Pinscore, Rottendog… To flag honestly: XPin announced the closure of its shop in July 2026 (support for existing products and authorised resellers continues); Pinscore displays are still offered by PB Resource, but availability varies by reference. Supply has tightened: check stock before counting on it.

Estimated cost: ~50-65 € (reconditioned) to ~80-150 € (new LED display, subject to availability).

Added value: a readable score reassures immediately, and it's a point the buyer always tests. Medium but real impact. Given the current pressure on LED displays, a working reconditioned original is often the right compromise.

9. Small details that sell

The weak point: a thousand little nothings that, added up, say "neglected" — scratched glass, a dull lockdown bar, yellowed buttons, a dusty cabinet interior, and above all poor advert photos.

The options (almost free):

• A new playfield glass (~30-60 €) or, at the very least, cleaned on both sides.
• Lockdown bar and rails polished (metal polish, a few €).
• New flipper buttons (a few € a pair).
• Cabinet interior vacuumed and cleaned, loom tidied.
• Careful advert photos: machine switched on, clean playfield, decent light, neutral background.

Estimated cost: 0-60 €.

Added value: disproportionate at the point of sale. These moves cost almost nothing and radically change the perception. An advert with fine photos of a machine that is switched on and clean gets more enquiries and is haggled down less — that's market logic, not a numbered promise.

Where to start?

Spend first where every euro invested returns the most. Value/effort order of priority:

1. Make it start up and play reliably (electronics) — absolute priority.
2. New balls + rubbers — a few euros, immediate feel.
3. Full clean (cabinet, playfield with Novus, glass) — free or nearly so.
4. LED lighting of the key areas — big visual effect, small budget.
5. Small details (buttons, legs/levelers, lockdown, photos) — the finishing touch.
6. Only then, and only if the model justifies it: repro backglass, stencils, repro playfield.

Golden rule: function > cleanliness > heavy cosmetics. And never over-restore a common game. To place your machine's value before investing, see how much is my pinball machine worth and the guide restoring a vintage pinball machine.

FAQ

Which repair increases the value of a pinball machine the most?

Making it start up and play reliably. A working machine is worth far more than a dead one: it's the number-one lever, well ahead of the looks. Always start with the electronics.

Does repainting the cabinet increase the value?

Not always. A clean, yes; but a botched or "too new" repaint can lower the value in the eyes of collectors, who are attached to originality. Only repaint if the cabinet is genuinely damaged, and do it cleanly.

Should you repair the original board or replace it?

Repair if the damage is limited and you value originality (our rates: 20 € flat fee + 50 €/h + components). Replace with a battery-free board (from 99 € for one block, 349-399 € for a Gottlieb all-in-one) to make it reliable and remove the leaking-battery risk.

How much does a reproduction backglass cost?

About 255-320 € + shipping at CPR or Shay Arcade Group (prices recorded in July 2026). Stabilising an original that is starting to flake with Triple Thick costs ~15-25 € and preserves the original part.

Are LED kits worth it?

Yes, an excellent effect-to-price ratio: from a few LEDs at 0.60 € each up to a full kit at 70-160 €. Prefer warm white for the vintage atmosphere and non-ghosting LEDs on matrix machines.

Does Pinballs Store do all this?

No. We design and sell FPGA replacement boards and we repair boards (electronics). For LEDs, legs, stencils, backglasses and displays, we point you towards the specialist suppliers cited here. A board fixes the electronics, not the mechanics.
