Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
---|---|---|---|---|---|
Sony | STRVX6 | POOR CONNECTIONS ON Q414 | This unit had a dim display and erratic tuning Q414 was foundto be poorly soldered on the base and emitter leads. | ||
Sony | PSX75 | ARM NEEDED ADJUSTMENT | Cantilever of cartridge was being pulled to one side, bendingit eventually also mistracking in one channel, poor dynamic range, etc. | ||
Sony | ICF2001 | ERROR IN PCB DIAGRAM | When RD amp fails, technician replaces Q52 as labeled on PCB,diagram is incorrect. | ||
Sony | CFS10 | END OF TAPE SENSOR NOT ALIGNED | As tape moves in play mode - end of tape sensor is not alignedfully with width of tape causing uneven pressure and wrinkling of tape. -HQ COMMENTS: The crease in the tape is indeed caused by excessivepressure as well as uneven placement of the PU lever | ||
Sony | AUDIO GEN | T/N #8467 | T/N #8467 list IC CX807-F1 and CX807-F3 as applicable to WM-2.However WM-2 uses CX808 on first and second type board an CX887 on thirdtype board. Is CX807-F1 and CX807-F3 replacement for CX808 or CX887? -HQ COMMENTS: CX-807 and CX-808 ICs are identical | ||
Sony | XR70 | TAB ADJUSTMENT NEEDED | It will not accept tape. Cause: Eject lever (#387) fails toengage the pin on (#385) when tape is inserted. | ||
Sony | XO5 | DEFECTIVE SWITCH | This unit had a bad hum in the phono mode (unless the switchwas pushed in and held in hard). The small switch (muting) along side S2would not make contact unless switch was held in. | ||
Sony | WMD6 | FOIL MISSING | No FF and REWIND. Motor started about 2-3 seconds after theplay switch is pressed. | ||
Sony | TCM5 | MISSING PARTS IN S/M | The mechanical layout on page 15 of the S/M is missing parts. | ||
Sony | TCFX1010 | BROKEN ERASE HEAD WIRE | This unit had a distorted output at the P/B head(non-symetrical sine wave). This of course prevented the auto calibrationcircuit from functioning. We found a broken wire at the erase head to bethe problem. | ||
Sony | TC530 | REPLACEMENT MOTOR IS LARGER | IC624-SI motor substituted by P/N 8-832-627-00, type IC624HI. Servicer states motor sub is physically larger and mounting holesare different. -HQ COMMENTS: Motors are direct replacement.IC624-SI Motor (8-832-624-09/02) = IC624-HI Motor (8-832-627-00) | ||
Sony | TC250 | REPLACEMENT PART DIFFERENT | X-346-011-0 is too small in diameter. The other idler part #X-027-003-0 looks more like correct diameter. -HQ COMMENTS: TC-250 unit is approx. 15 years old. Similar model isTC-350 and TC-102. P/N for its idler is X-002-701-92 and currentlyavailable. | ||
Sony | STRVX6 | DEFECTIVE IC503 | This unit erratically displayed two or three LED segments.We found the drive IC to be defective. | ||
Sony | STRVX6 | REPEATED INVERTER FAILURE | Unit had been serviced twice before for inverter transistorfailure. First time, it was modified by moving Q801 regulator transistor.Second time, unit was cooked 2 weeks. Before being sent back to customer,where it failed again after 3 hours of operatio | ||
Sony | SPP11 | DIALING PULSE DOES NOT GO THROUGH | Intermittently when dialing out gets a busy signal and thenumber being called rings only once and then dead line. -HQ COMMENTS: Although no history of such a problem, there are twothings I can think of for an incomplete call. 1) The dialing pulse width |
