|---|---|---|---|---|---|
| Sony | CCDV8AFU | ALIGNMENT METHOD INCORRECT | On page 205 of S/M, adjustments in AF section 1-34-3 areincorrect. Test point for 5.5V adj. should be collector of Q022, notemitter. VCF adj. is unclear. D001 cathode must be shorted to 1.7V line.Also, in offset adj., it specifies shorting 1.7V line t | ||
| Sony | CCDV8AFU | NO CAPSTAN PHASE LOCK | Noise bar at 5 sec rate. Observed RF envelope expand to maxand diminish. By substituting ATF servo with power supply could stabilizepicture. All signals at ATF servo/IC106 appeared OK, but replacementsolved problem. Hint: wait for RF envelope to dimi | ||
| Sony | CCDV8AFU | VIDEO WAS GOOD BUT EVERYTHING WAS PINK | Video was good but everything was pink. Traced problem toME-1 board. Good signal TP703. No signal TP704. Signal OK Pin 48 butDC voltage 4.8V. Trace to leaky chip cap C711. | ||
| Sony | CCDV8AFU | NO POWER | No power, all voltages normal out of DR901, VDD normal toIC601. Found no clock at IC601. | ||
| Sony | CCDV8AFU | TAPE HESITATES | Intermittent tape hesitation during tape run record or PB.Momentary tape stoppage at random intervals progressing to emergency stopalthough normal immediately after reset, continue operation finallyobtaining complete failure of tape movement in all modes | ||
| Sony | CCDV8AFU | WON'T RECORD | Won't record, unable to enter any mode except eject, drum runfollowed by emergency stop. Found no RF SW pulse Pin 24 IC601/MC-4 board.No output Pin 7 IC501 on MC-4 board, incorrect DC level Pin 6 IC501. | ||

During playback any tape including self-recordedpicture would break-up with white streaks and speed would change back andforth between SP/LP modes. Troubleshooted ATF circuit to no avail.Changed UI-6 board with known good board, same thing. | ||
| 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 | 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. | ||
