In this set-up, the GND | ||
| Sony | TCFX510R | MALFUNCTIONING IC601 | This unit would intermittently go into reverse and the counterwas inoperative. We found IC601/System Control IC to be defective. | ||
| Sony | TCFX600 | RELAY NOT TOGGLING PROPERLY | In playback, when going from Dolby off to Dolby C, unitbreaks into oscillation in both channels. When going from Dolby B, toDolby C, no problem. Unsoldering either Pin 2 or 8 of IC001 cures theopposite channel. | ||
| Sony | TCFX7 | INCOMPLETE INSTRUCTIONS IN MANUAL | Page 22 of S/M, instructions for servo adjustment areincomplete. Step 7 should refer to Pin 21 of IC902 for pulse adjustment. -HQ COMMENTS: As you pointed out, the TP (silk-screened as SPEED) isnot shown for the #7 in the adjustment procedures. The Pi | ||
| Sony | TCFX505R | MALFUNCTIONING AMS MODE | No music scan or FWD AMS operation. Found that head chassiswas not staying up in AMS position, thus the RP head was not reading anyaudio off the tape. | ||
| Sony | TCFX30 | ERROR IN S/M | In the schematic section (Pages 24B, 25 of both manuals)R321 and R322 are mislabelled as R332, R321 respectively. Also a missingconnection line exists in both service manuals. It is located to theleft of the mislabelled resistors. -HQ COMMENTS: The sc | ||
| Sony | TCFX77 | MANUAL CORRECTIONS | The hardwire diagrams for both the TC-FX77 and TC-FX600 haveerrors. The schematic diagrams appear correct. Q504, Q506 are shown asNPN transistors incorrectly, they are PNP. | ||
| Sony | TCFX505R | WORN THRUST BEARING | The unit would intermittently produce large amount of wow &flutter in the reverse direction. We traced the problem to the capstanthrust bearing. The plastic had lost its SPRING and was permittingexcessive thrust play. | ||
| Sony | TCFX500 | WORN CAPSTAN BEARING | The customer complained of an intermittent pop in bothchannels when playing the tape in the reverse direction. We found thecapstan bearing (reverse direction) to be providing a poor ground. | ||
| Sony | TCFX45 | WORN THRUST RETAINER | This unit skewed TDK SA and MAXELL UDX tapes at the verybeginning. We found that there was too much play in the capstan. Thiswas caused by the plastic thrust retainer becoming slightly distorted. | ||
| Sony | TCFX7 | EXCESSIVE WOW AND FLUTTER PLUS MOTOR NOISE | Motor comes with plastic clutch, which in time will comeflush against motor bearing, causing a grinding noise and wow and flutter.One solution is to put a small plastic washer at clutch shaft assy tostop it from going inwards against motor bearing. -HQ | ||
| Sony | TCFX44 | DEFECTIVE RY301 | This unit would play back fine. However when recording therewere intermittent passages with MOTORBOATING. We found RY301 (whichswitches the head between PB and REC) to be defective. This caused a poorground connection on the head. | ||
| Sony | TCFX77 | MISSING PART # IN MANUAL | There is no P/N for the capacitor C134, 234 (56pF/500V),which are connected to the R/P head, in the service manual. | ||
| Sony | TCFX44 | DEFECTIVE RELAY | Erratic system control operation. When record button isdepressed, unit will intermittently enter rewind mode after 2-3 sec(record deactivates). Results from high resistance of relay contacts. | ||
| Sony | TCFX44 | DEFECTIVE C505 | With the cassette door open and power applied, this deckwould go into play mode, although the play led was not lighted. |
