| Sony | TCFX310 | CIRCUIT CORRECTION IN SERVICE MANUAL | Circuit from Pin 15 of IC502 is improperly routed to theerase prevention switch (S711). Pin 15 should connect to circuit betweenS711 and S701 (control switch board). -HQ COMMENTS: Your analysis of the problem is correct. We will issue aservice bulleti | ||
| Sony | TCFX310 | DESIGN CHANGE IN REMOTE CIRCUIT | Unit would switch and stay in record mode when remote cablewas connected. Found IC502 bad and also a shorted diode which is notshown in service manual. This diode is connected to Pin 16 of IC502 andground. I would like to know the P/N of this diode AS | ||

| Sony | XR40 | NO AUDIO OUTPUT | No sound on radio or tape, unit has power. Front panel LEDsindicate normal operations. Signal tracing showed audio getting to inputsof IC302 but not coming out, voltage measurements on IC302 were wrong dueto broken ground path (Pins 5 and 9 read 3.7V i | ||
| Sony | KV1997R | INCORRECT RESISTOR VALUE, R561 SHOULD BE 6.8 KOHMS | Schematic (P25) and parts list (P38) both indicate R561resistor (in the collector circuit of Q501, horizontal drive transistor)should be 6.8 ohms. In fact, in the unit this is 6.8 kohms, which agreeswith other models in the P3 chassis series. -HQ COMME | ||
| Sony | STRVX5 | PART NUMBER FOR FRONT PANEL ASSY IS NOT IN S/M | Part number for front panel assy is not in S/M but is listedon parts microfische. -HQ COMMENTS: Part number is X-4877-106-1. We will issue a S/B. | ||
| Sony | XR65 | NO AUDIO OUTPUT | No output to speakers. Signal was getting to output IC butnot coming out. DC voltages on IC were wrong, so I changed the IC, stillno output. Resistance measurements on IC revealed short from Pin 3 toground, found shorted capacitor C339. | ||
| Sony | KV1966 | DOES NOT TURN ON, REPLACE HDT T501 | No high voltage, horizontal oscillator is working but verysmall pulse will reach the base of the horizontal output. | ||
| Sony | SL5000 | INTERMITTENT SPEED ON BIII PLAYBACK | Tape speed intermittently changes on BIII playback. Unitrecords fine on BIII, BII and playback is good on BII. | ||
