| 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 | PSX45 | IC CX193 FAILS | This unit has repeated failure of the servo IC, CX193. Alloutboard parts have been carefully checked and the unit operatescorrectly when a new IC is installed. All D.C. and waveform measurementsare within 5%. I am puzzled as to why these chips only wo | ||
| Sony | PSX6 | LEAKY D410 | After 5 minutes the repeat led would partially come on andthe repeat function would not work. We found D410 in the repeat flip flopckt leaky. | ||
| Sony | PCMF1 | LEAKY L519 AND DEFECTIVE IC505 | Recording section worked fine but the playback section didnot function. | ||
| Sony | CDP101 | DEFECTIVE LASER | Unit will not read TOC (ejects after attempting to focus3 times). Defective laser diode - all voltages to TOP correct - LD ONsignal good. | ||
| Sony | CDP101 | DEFECTIVE Q601 | Initially there was no system control function due todefective crystal. After replacing crystal unit worked OK for a fewminutes but shut down when jarred. Traced problem to defective Q601 whichshorted because of misaligned rubber insulator. I think th | ||
