| Sony | CDP701ES | PLL ADJ | In 1986, Kirk Vistain wrote a quicker and much easier way ofsetting PLL freq., but it is not listed in SDIS: #1 Short junction of R142 and C132 to ground. #2 Put unit into test mode, test SW701 to VS. #3 Power on. #4 Adjust L201 for 4.3218Mhz and RV2 | ||
| Sony | CDP707ESD | INTERMITTENT PLAYBACK | Customer said unit would intermittently skip and stop playing.Unit had been at authorized shop two times (FOP changed once). Testedunit with no evidence of problems. Upon pressing on IC-101 (RF IC) RFpattern distorted and dropped out. As only pressing | ||
| Sony | CDP701ES | APC ADJUSTMENT PROCEDURE | The attached FPR from 10/23/85 (not in computer) indicatesthat it would be issued on how to adjust the laser output but I cannotfind any such Service Bulletin or Supplement etc. Was this ever issued?What is the adjustment procedure? -HQ COMMENTS: When | ||
| Sony | CDP701 | REPLACEMENT OF IC-602 | New IC does not work. | ||
| Sony | CDP707ESD | MISSING PART NUMBER | The part number for the rotor assembly which sits above Ref.No. 926 is not listed in the service manual. -HQ COMMENTS: The part number is the same as listed in the CDP-X7ESDmanual. It is A-4675-324-A. | ||
| Sony | CDP707ESD | DOES NOT READ DISC | Unit will not read disc. After loading, the disc will spinforward for a second then spins backwards and shuts down-then (Disc Memo)appears on the display. | ||
| Sony | CDP701ES | HIGH FREQUENCY WHISTLE IN ONE CHANNEL | High freq. whistle in one channel. Found cold solder joint onLPF ground tab. This problem could occur on LPF401 effecting other side. | ||
| Sony | CDP70 | SKIPPING DUE TO RESTRICTION OF SLED MOTOR MOVEMENT | When replacing sled motor, room must be made in housing formotor to track properly. | ||
| Sony | CDP707ESD | NO PLAY (KEEP TURNING THE DISC) | 1) FOP sled lock lever was out of position and prevented FOPfrom getting into inner position. 2) No part number for this lock lever. | ||
| Sony | CDP70 | UNIT WOULD NOT READ TOC | Unit had been severely misadjusted, including laser power onFOP. Adjusted unit and it appeared to be spinning disc at correct CLVspeed, but TOC would not be read and GFS was low. | ||
| Sony | CDP70 | NO OPERATION AND NO DISPLAY | When unit was powered on, there was no display and unitwould not operate. | ||
| Sony | CDP70 | INTERMITTENT SKIPPING | I found that it would require a higher DC voltage to drivesled motor at or around the first track. | ||
| Sony | CDP701ES | NOISE DURING SCAN | Clicking noise is heard when scanning to the next selection.All power supply filter capacitors have been changed, also the regulatorICs (+/-12V, +/-5V). No change. Found out that this noise did not appearuntil the STK6922 were replaced with BX1201. | ||
| Sony | CDP70 | INTERMITTENT SKIPPING | Unit would skip tracks intermittently at random. Tracedproblem to cold solder on M701 minus terminal. Have seen several unitswith either + or - terminals cold soldered. Since motor is assembled intoboard, this could be a problem on similar models also | ||
| Sony | CDP70 | UNIT WOULD NOT PLAY THE DISC | Unit would focus but would not read TOC. TE test point showederratic wave form but grounding IC102 Pin 13 showed good traverse waveform. Pressing on PCB near IC102 would cause proper operation. |
