Panasonic Q General Maintenance
The Panasonic Q (SL-GC10) is a GameCube mainboard inside a Panasonic DVD player, so its upkeep is the GameCube's plus the Q's own parts: the DVD drive with its plastic rails and tray belt, an internal mains supply, a fan, an LCD panel, a large number of ribbon cables and a backup battery. For the GameCube board itself (cooling, thermal pads, chips, controller ports) use the Nintendo GameCube Maintenance Guide. That guide's optical drive sections cover Nintendo's 8 cm drive, which the Q does not have.[1][2]
Panasonic's operating instructions are on the Internet Archive and with Panasonic Japan; no service manual for the SL-GC10 is among the Internet Archive's holdings. Board-level details come from Console5's capacitor lists, RetroSix's bench notes and owners' repair reports.[3][4][5]
Safety
[edit | edit source]- Panasonic rates the Q for AC 100 V, 50/60 Hz and for use in Japan only, because mains voltages differ elsewhere.[3] Where the mains is higher, run it from a step-down transformer of adequate rating.
- Unplug the Q before opening it. The AC power board runs the standby supply and is live whenever the plug is in; the POWER button only switches a relay on that board.[5]
- The main power supply board carries a 150 µF, 200 V primary reservoir capacitor, C903.[4] Measure across it before touching that board after unplugging.
Cleaning
[edit | edit source]Panasonic's care instructions (operating instructions, p. 58):[3]
- Wipe the case with a soft cloth. For heavy dirt use a cloth dampened with diluted neutral kitchen detergent, then wipe dry. Do not use alcohol or thinners; follow the instructions of any chemically treated cloth.
- Clean the lens periodically with a lens-cleaning disc. Panasonic names its CD lens cleaner RP-CL510.
- Wipe a dirty disc with a soft cloth dampened with water, from the centre outwards, and dry it.
- Wipe off condensation with a dry, soft cloth. After bringing the Q from a cold place into a warm room, leave it for one to two hours before playing a disc, since dew can form on the lens.
- Store it away from direct sun, damp and dust, and heater outlets.
Opening the case
[edit | edit source]BEEP's repair report gives the order: take off the left and right side covers, then lift off the top with the LCD. Several cables join the top to the rest of the machine, so lift it carefully and unplug them before moving it away. The drive is then exposed.[6] RetroSix's photographs and connector letters for every ribbon are summarised below; note each connector before unplugging it.[7]
Ribbon cables and connectors
[edit | edit source]| Connector | From | To |
|---|---|---|
| A | Top lid | Side board |
| P | Top lid | AC power board |
| O | Top lid | Optical decoder board (power) |
| R | Top lid | Optical decoder board (data) |
| S | Top lid | Front board |
| F | Front board | GameCube board (controller ports) |
| B, C, E | Side board | AV decoder board |
| H | AV decoder board | Optical decoder board below it |
| Q | Optical decoder board | Laser trim settings |
| V | Optical decoder board | Laser assembly |
| D | Optical decoder board | GameCube board |
| G | GameCube board | AV port ribbon |
| T | GameCube board | Side board (composite video and audio) |
| L, J | GameCube power board | GameCube board (L) and side board (J) |
| M | DC power board | GameCube power board (12 V) |
| N | DC power board | Side board (12 V, −12 V, 5 V, 2.5 V) |
[7][5] Connector Q holds the trim settings for the laser; leave it plugged into the board it came from.[7]
Disc drive
[edit | edit source]Tray rails and drive mounts
[edit | edit source]The left and right tray rails are moulded plastic and break. Hitman's Museum found the left rail of one Q in pieces; glued, it worked, and it was later replaced with 3D-printed rails.[8] A GC-Forever member had the rails of a Q break in the post, glued them, and had them smashed again on a second journey along with the lens. The donor drive bought to replace it had broken rails too.[2] BEEP opened a Q that rattled and found pieces of the plastic that holds the drive in place, with other cracks nearby, and on further reading found that a high proportion of Q drives are damaged, some with the plastic in pieces and past repair.[6]
Printable rails and a printable tray are published on Thingiverse, and printed rails are also sold.[9][10] The GC-Forever member's printed rails were mirror images of each other, but the tray's running slots are slightly narrower on the side with the opening gears, so the rails needed about fifteen minutes with a file to fit.[2] Check the fit of both rails in their slots before fitting the tray.
Tray belt
[edit | edit source]A perished belt stops the tray opening or closing. The belt is just inside the front of the drive when the tray is open, but it cannot be changed from there. Take off the drive's lid, pull the tray fully out, and remove the gear above the belt to fit the new one.[6] RetroSix gives the replacement as a "50mm half-diameter" belt.[11] BEEP found an excess of old grease on the gears, cleaned it off before taking them out, and greased them again on reassembly.[6] Hitman's Museum found a deformed belt alongside the broken rail on its Q, and the GC-Forever member's belt had also failed.[8][2]
Pickup
[edit | edit source]The pickup is a Panasonic RAF3011A, moved by a motor (MDN2BL3CRQ). Switch S1 is closed when the pickup is at the spindle end of its travel and open when it is out over the disc.[12] The laser's trim settings are held on the board on connector Q.[7] After moving a donor drive into a Q, one owner had to adjust the laser potentiometers to match the original drive before DVDs and GameCube discs played.[2] The drive wiring is shown in File:Panasonic Q SL-GC10 drive mechanism wiring diagram.png.
Fan
[edit | edit source]The fan is on the left side and runs only in GameCube mode.[1] The original is a two-wire fan. RetroSix has a report, which it has not yet repeated itself, of a three-wire replacement fan causing the F76 shutdown until its third wire was tied to the supply wire.[13] Check the fan with a game running, since it stays still in DVD mode.
Backup battery
[edit | edit source]If the GameCube side reports at every power-on that its settings have been lost and the date and time reset, Panasonic's instructions say the internal battery may be exhausted.[3] Panasonic does not give the cell type or its position. In the retail GameCube the clock cell is a tabbed CR2032 on the controller port board;[14] the Q's controller ports are on its own front board,[7] so read the cell off the board in your Q before ordering. Check the area round it for corrosion; see Battery Explosion, Capacitor or Corrosion Damage.
Capacitors
[edit | edit source]Console5 lists electrolytic capacitors on the DVD, AV, LCD and both power boards, as well as the GameCube boards. The full list is on the Panasonic Q Capacitor Replacement Guide.[4] Hitman's Museum recapped the GameCube board of its Q while fitting an optical drive emulator.[8]
Spare parts
[edit | edit source]Panasonic kept repair parts for the SL-GC10 for eight years after production ended.[3] Parts now come from donor Qs, from printed replacements and, for the drive, from the Panasonic DVD players that GC-Forever reports share it.[2] Console5 sells a replacement tray belt for the Q alongside its capacitor kit.[15]
