Philips Odyssey 2100 board layout (CS43618)
Philips's board layout for the Odyssey 2100 (service manual CS43618, p. 3). C1 is drawn in dashed outline beside IC1 and the RIGHT and LEFT connectors; C2 and C5 are at the top, near IC4 and TS1.

The Philips Odyssey 2100 (type G7513) has three aluminium electrolytic capacitors, C1, C2 and C5, all on the main board. Philips's service manual CS43618 gives the value, voltage rating and 12NC number of each in its parts list, shows them on the schematic and marks their positions on the board layout.[1] For the general signs of a failed capacitor see Capacitor Failure Symptoms.

Before replacing anything

[edit | edit source]

The console runs from a plug-in mains adaptor, so there is no mains voltage inside it; the highest voltage on the board is the adaptor's output across C1.[1] Philips's manual names no capacitor as a known fault. Measure the supplies first, with the meter's black lead on circuit ground (for example IC1 pin 12): -12 V on line B and at IC3 pin 5, and -8 V at IC1 pin 7.[1] If both are right and steady, C1 and C2 are working. C5 sits on IC1 pin 22 and does not show in these readings.

Electrolytic capacitors

[edit | edit source]
Odyssey 2100 (G7513) electrolytic capacitors
Ref Value Rating Philips 12NC Circuit (schematic) Position (board layout)
C1 1000 µF 25 V 5322 124 24067 Across the adaptor input at BU1, terminals A and B, ahead of the regulator IC4 Beside IC1, next to the RIGHT and LEFT connectors
C2 10 µF 16 V 5322 124 14066 Across the regulated supply, line B (-12 V) to ground, at IC4 Near IC4, to the right of IC2
C5 1 µF 25 V 5322 124 14096 IC1 pin 22 to ground, with R3 (68 kΩ) from -12 V Near TS1 and R3, at the top of the board

  • C1 is the only smoothing for the adaptor's output. The schematic shows U1 as a transformer and bridge rectifier with no capacitor of its own, and marks 24 V across BU1.[1] A C1 that has lost capacitance leaves 100 Hz ripple on the regulator's input.
  • C1 is rated 25 V against the 24 V on the schematic. The adaptor in the owner's photographs is rated 18.6 V at 120 mA; measure your own adaptor's output with the console connected. A 35 V part of the same capacitance gives more margin if it fits the space.[1][2]
  • The board photographed has a blue Nichicon 1000 µF 25 V 85 °C part in the C1 position, lying on its side, and two small blue electrolytics near the regulator IC-4.[3]

Other capacitors

[edit | edit source]

The other 24 capacitors, C3, C4 and C6 to C27 (C13 is a trimmer), are ceramic and polyester parts between 4.7 pF and 100 nF; the schematic's symbols mark which is which.[1] Several are part of tuned circuits and must be replaced with the same value and type, followed by the matching adjustment on Philips Odyssey 2100 General Maintenance:

Capacitors in the tuned circuits (schematic and adjustments)
Ref Value Circuit Adjustment after replacement
C11 100 pF 5.5 MHz sound tank with S1 5.5 MHz oscillator (S1)
C13 2–22 pF trimmer 4.43 MHz oscillator with KT1 4.43 MHz oscillator (C13)
C14, C15 47 pF 4.43 MHz oscillator network at IC3 pins 18 and 1 4.43 MHz oscillator (C13)
C17 82 pF Channel E4 oscillator coil S2 Channel E4 (S2)
C19 100 pF Channel E3 oscillator coil S3 Channel E3 (S3)

[1][4]

C17 on the board photographed is a ceramic disc marked 82, 10 % and NPO.[3]

Procedure

[edit | edit source]
  1. Unplug the adaptor. Turn the console over, turn the central screw to the left and lift off the bottom case.[5]
  2. The board is screwed into a corner of the top case, with the regulator on a metal bracket. Note where the controller, aerial and adaptor-socket wires go before freeing the board.[6]
  3. Find C1, C2 and C5 on the service manual's board layout. The board's own silkscreen uses different designators in places (for example Q1 for TS1), so go by position.[1][3]
  4. Note the polarity marking on the board for each capacitor. C2 sits on the negative supply: its positive lead goes to circuit ground, not to the -12 V line.[1]
  5. Desolder one capacitor at a time and fit the new one the same way round.
  6. Refit the board, reconnect the adaptor and measure -12 V on line B and -8 V at IC1 pin 7 before playing.[1]

Parts

[edit | edit source]
  • C1: 1000 µF, 25 V or higher.
  • C2: 10 µF, 16 V or higher.
  • C5: 1 µF, 25 V or higher.

Use radial aluminium electrolytics rated for 105 °C. For tools, see Recommended Tools.

Post-recap checks

[edit | edit source]
Supply readings after a recap (schematic, relative to circuit ground)
Point Expected
BU1, A to B 24 V
Line B, IC3 pin 5, IC1 pin 14 -12 V
IC1 pin 7, IC1 pin 4 -8 V
IC3 pin 13 -8 V
