Repair: Toshiba PB-7534 (Konami Windy 2)¶
The Toshiba PB-7534 (-1) chassis is the factory monitor of the Konami Windy 2 (and other cabs). It is a tri-sync 15 / 24 / 31 kHz (low / medium / high resolution). Standard CRT repair: HV discharge, recap (mind the bipolars and the 4 filters outside the kit), reflow, HOT/flyback.
Identification¶
| Field | Value |
|---|---|
| Manufacturer | Toshiba |
| Chassis | PB-7534 / PB-7534-1 |
| Type | colour tri-sync CRT |
| Frequencies | 15 / 24 / 31 kHz (auto — low/medium/high res) |
| Cabinet | Konami Windy 2 (factory), others |
Safety (read first)¶
High voltage — discharge the tube
Lethal high voltage held while unplugged → discharge the anode. See CRT safety & HV discharge. Isolation transformer for powered measurements.
Common faults¶
| Symptom | Likely cause | Lead |
|---|---|---|
| No picture / no HV | HOT, flyback, +B supply | Check HOT / flyback / +B |
| Unstable image / flicker | dried electrolytics (recap) | Recap |
| Intermittent dropouts | cold solder joints | Reflow |
| Won't lock at 31 kHz | tri-sync switching / sync | Check sync + detect stage |
| Blur / washed-out colours | flyback focus / neck board | Adjust focus, diagnose neck board |
Repair (method)¶
- HV discharge → CRT safety.
- Recap (method) — the PB-7534 kit has 51 capacitors including 3 bipolars (C413, C442, C445). ⚠️ 4 filters are NOT included in the kits, order separately: 3 × 470 µF/250 V + 1 × 1000 µF/200 V.
- Reflow the joints (neck, flyback, deflection connectors).
- HOT / flyback = wear; focus / screen (G2), geometry adjustments.
- Tri-sync: if 31 kHz won't lock, check the sync type and the frequency-detect stage.
Cap kits & parts¶
- arcadepartsandrepair — Toshiba PB-7534-1 (Nichicon 105 °C, 51 caps incl. 3 bipolars) · ⚠️ 3×470 µF/250 V + 1×1000 µF/200 V filters separately; cross-check against your board.

Review & corrections
How this space is used
Spotted a wrong value, an outdated procedure, a chip reference that does not match your board? Say so here, with what you observed (model, board revision, serial number, measurement). Every report is cross-checked against a source before anything changes — an unverifiable correction is published as “reported by …, not cross-checked” rather than silently applied.
Reading is open to everyone; posting requires signing in with Discord. Reports from the wiki's declared reviewers are handled first; anyone else's are read too, but go through a human before anything is changed.
