Panasonic FZ-10 General Maintenance

From RetroTechCollection
Panasonic FZ-10

The Panasonic FZ-10 comes apart in a fixed order: top case, traverse unit, power board, then main board. The order, the service notes and the part numbers below are from Panasonic's U.K. service manual, IMD9504003C2.[1]

Safety

[edit | edit source]
  • Warning: the power board runs from the mains, with its reservoir at about 130 V (120 V boards) or about 310 V (230–240 V boards). The power switch acts on the control side, so the primary is live whenever the lead is plugged in.[2][3] Unplug the console and let the board discharge.
  • Fit the power board cover while working on the main board, and keep clear of the metal parts of the power section.[1]
  • Replace the mains fuse only with the same type, 2 A, 250 V.[1]

Disassembly

[edit | edit source]

Before starting, remove any disc, switch off, unplug the mains lead and remove any optional units. Panasonic warns against interchanging screws between parts of the console.[1]

Top case

[edit | edit source]
  1. Turn the console upside down.
  2. Remove the seven screws A.
  3. Turn it back over and lift the top case off.

Traverse unit

[edit | edit source]
  1. Push the two pins B out from underneath.
  2. Remove the traverse cover.
  3. Raise the traverse unit and unplug its five connectors, including CN760 and CN762, then lift it out.

Power board

[edit | edit source]
  1. Remove the power board cover.
  2. Release the four hooks C and remove the AC inlet and the power switch.
  3. Remove the two screws D.
  4. Unplug CN101 and lift the power board out.

Main board

[edit | edit source]
  1. With the top case and traverse unit off, remove the LED guide panel.
  2. Remove the five screws E and the upper shield plate.
  3. Remove the FMV cover on the right side.
  4. Remove the two screws F.
  5. Unplug CN420 and lift the main board out.

Lid

[edit | edit source]

The CD panel comes off after releasing its two hooks G and removing the lid's hop-up spring and oil damper. The part Panasonic calls the DC latch comes off after releasing two hooks H.[1]

Reassemble in the reverse order.[1]

Service notes

[edit | edit source]
  • To play a disc with the lid open, tape down the lid switch SW720.[1]
  • When measuring the waveforms Panasonic marks on its schematics, measure from the underside of the assembled unit.[1]
  • Panasonic's service tools for the FZ-10 were an extension flat cable for the power supply (DFWV95C0103), an FZ-10 checker with manual (DFWV95C0104) and its cable (DFWV95C0105), a traverse platform for working under the traverse (DFWV95C0106) and a set of extension cables (DFWV95C0107 to DFWV95C0111).[1]

Laser and drive

[edit | edit source]

The laser diode is sensitive to static. Wear an anti-static wrist strap, work on a conductive sheet, keep clothing away from the pickup and leave its shorting point bridged while it is out. Do not touch the lens or turn the laser power preset.[1] The 3DO Development Repo notes that a dirty lens can be cleaned but a fogged or scratched one needs a new pickup, and that setting the laser current needs an oscilloscope.[4] The laser is the Sanyo SF-92.5 in its short-wire version.[5] A printed replacement for a CD-ROM pin of the FZ-10 is published on Thingiverse, and a printed AV expansion door is published on Printables.[6][7]

Back-up cell

[edit | edit source]

Saved games are held in 32 KB of SRAM backed by a 3 V lithium cell, BT400, which the U.K. parts list gives as a CR2032.[1] Check it and the board around it for corrosion whenever the console is open; see Battery Explosion, Capacitor or Corrosion Damage.

Checks while the console is open

[edit | edit source]
  • Look for leaking or bulging electrolytics on both boards. Values for each board are on the Panasonic FZ-10 Capacitor Replacement Guide.
  • Check the joints on the video and audio sockets; cracked joints give a picture on some outputs only.[4]
  • Clean the expansion port contacts; a dirty port causes failures with an XPort optical drive emulator.[4]
  • With the power board refitted and the main board unplugged, check +9 V on CN101 pins 1–3 and +5 V on pins 13–17.[2][3]
