|---|---|---|---|---|---|
| Sony | CCDV8AFU | BREAKS TAPES ON EJECT | The unit breaks or streaks the tape on eject. We found theproblem to be caused by guide number 8. The guide was severely pinchingthe tape. This of course lead to excessive take up torque. Surprisinglythe unit worked fine in PB and REC. Readjustment | ||
| Sony | CCDV8 | VIDEO DROPOUTS DURING PLAYBACK | Replaced drum assy and AR-1 board, no help. -HQ COMMENTS: Check IC101 (dropout det. circuit), IC102 (dropoutcompensator), and DL101 (1H delay) on the VI-6 board. Please informresults. | ||
| Sony | CCDV8 | NO CAMERA POWER | Camera DC-DC converter (DR902) goes dead when AW-1 board isconnected to it via CN702. -HQ COMMENTS: Lift each wire from CN702 (one at a time) until you canisolate which voltage is being pulled down. Check for shorted 2V or 3Vregulator circuit on AW-1 b | ||
| Sony | CCDV8AFU | FOUR VERT. LINES IN PICTURE DURING E-E OR CAMERA RECORDING | Four evenly spaced vertical lines appeared in pix during E-Eor camera recording. Also appears during self recorded playback. | ||
| Sony | CCDV8AFU | UNIT SHUTS DOWN IN FF OR REW | Will FF or REW for about 100 on counter, then unit shuts off. | ||
| Sony | CCDV8 | NO COLOR RECORDING | No color in E-E or recording. Playback of pre-recorded tapesOK. | ||
| Sony | CCDV8AFU | INTMT WHITE CLOUD IN BOTTOM RIGHT OF PICTURE | A white cloud would intermittently appear in lower right edgeof picture. Would slowly change in size until entire picture becamewhite. | ||
| Sony | CCDV8AFU | PICTURE DISTORTION DURING PLAYBACK | 1) Capstan servo would not lock during playback. ATF errorvoltage (IC106, Pin 25, VI-6 bd) at 4VDC. No output at IC106, Pins 11 &12. 2) Capstan also stopped intermittently during playback. Pin 8 ofCN511, SV-13 bd, not fully extended. | ||
| Sony | CCDV8AFU | TAPE INTERMITTENTLY EJECTS WHILE THREADED WHEN PB IS ENTERED | 1) Tape intermittently ejects while threaded when PB button ispushed (causing tape damage). 1) Intermittent capstan rotation during PB. | ||
| Sony | CCDV8AFU | CASSETTE DOOR WON | Locked mechanism using mode selector jig. During loading unitwould intermittently thread fully, then unthread slightly causing pinchroller to repeatedly engage and disengage. | ||
| Sony | CCDV8AFU | UNIT SHUTS DOWN AFTER CAM POWER IS TURNED ON | When cam power only or cam + VTR power is turned on, unitshuts down after a few seconds of playback or recording. Playback offunction tape indicated no drum lock. Self recorded tape appeared locked. | ||
| Sony | CCDV8AFU | INTERMITTENT NO POWER ON | Sys. 5V was present, but mode control CPU, IC601, SK-7 bd,would not issue VTR on signal (Pin 19). | ||
| Sony | CCDV8AFU | DISTORTED CAMERA OUTPUT | Sample crystal changed oscillator frequency from 28.6MHz to5MHz after 10 minutes. | ||
| Sony | CCDV8AFU | TAPE JAMS AROUND DRUM DURING THREADING | When a new tape is inserted, and tape starts to thread, itjams around the drum assy. This happens because there is no excess tapewhich can be pulled out from take up reel. -HQ COMMENTS: Under normal operation, the tape is fast forwarded for afew second | ||
| Sony | CCDV8AFU | NO DRUM LOCK | Unit would not drum lock, sound distorted. Intermittent shut-down due to overheating of IC501, Q501 and L502 (too hot to touch). Usingscope checked outputs at IC501 Pins 3, 22, 24 and Pins - no output.Traced back to Q508 TF4 amp. |
