| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Sony | CCDF30 | DISTORTED PLAYBACK (NO SYNC) UNTIL UNIT WARMS UP/C-380 | When power is first applied, the video would lose sync forabout a minute. Video signal was good out of IC-360 pin 47, but thethe sync was clipped after it passed through C-380. | ||
| Sony | CCDF30 | NO RECORD VIDEO, PRERECORD PLAYBACK GOOD/REPLACE C-505 | The unit did not have any record playback due to missingrecord Y. Good record Y out of IC-362 pin 4, Q-405 base and emitter,but not on pin 1 of IC-365. | ||
| Sony | CCDF301 | INOPERATIVE/REPLACE Q-904 | The unit was completely inoperative. All the fuses and PS501were good. See page 105. | ||
| Sony | CCDF301 | SPOT IN PICTURE FROM CCD | There was a spot in the picture which was mostly noticeablewhen shooting a light or white surface. | ||
| Sony | CCDF30 | DISTORTED PICTURE ON PLAYBACK/REPLACE C330, C353, SS-86 BRD | The unit produced a distorted picture with pre-recorded tapesand would not record. The RF envelope appeared distorted and looked somewhat like a sinewave. The input to the ATF IC250 pin 40 was a perfectsinewave also. I traced the signal back to the he | ||
| Sony | CCDF30 | PLAY BACK COLOR IS OFF/4.2MHZ ADJUST/RV-364 | When playing back WR59NS color bar tape, there was no magentacolor. | ||
| Sony | CCDF301 | INOPERATIVE STOP COMMAND/R523, FU100 | The unit would intermittently not accept the stop command fromthe Stop switch/S-504 on the VK-14 board. Remote Stop worked fine. Theproblem was traced to R-523 on the FU-100 board. This is a pull upresistor on the K IN 4 line. The resistor had been i | ||
| Sony | CCDF30 | PLAYING LP MODE - BAD PICTURE | Symptoms seem to vary depending on which capacitor is bad andhow severe its failure. Symptom could be what looks to be a very dirtyhead, sometimes loss of color only, sometimes picture is ok but appears tobe in LP mode. Failures are on various models u | ||
| Sony | CCDF301 | MECHANISM LOADS, GOES INTO PLAY AND RECORD WITHOUT A TAPE | Unit would load without a tape and go into Play and Record.Had several units with the same problem. Technician had changed reelsensors and end sensors without correcting the problem. I repaired theunit by changing the mode control CPU on the FU-100 board | ||
| Sony | CCDF30 | DISTORTED VIDEO - COMES BACK IN BW WHEN BATT. VOLTAGE IS LOW | Video was distorted. Measured VCC at IC-362. Found 6.5instead of 5. battery down did not work. Turned power supply to 5.4 voltsand picture came back in black and white. Also observed IC-360 wasgetting very hot. | ||
| Sony | CCDF301 | DISTORTED VIDEO IN PAUSE/SLOW MOTION AFTER CHANGING BOARD | After changing the SS-136 board, there was distorted videoon special effects due to IC-501 (SYS CON) on the SS-136 board outputinga 5 volt square wave (RF SWP) on the HCHG (pin 10) line. There should beno output on this pin for this model or for the F-4 | ||
| Sony | CCDF30 | NO LUMINANCE FROM CAMERA | Unit displayed no luminance on monitor, color was correct butlooked like severe line separation like G1, G2, RB or RB2 was misadjusted.MX-2 board was previously changed. There was no signal at the G1 or G2test points. | ||
| Sony | CCDF30 | NO CAPSTAN ROTATION | No capstan rotaion. PWM jumps high out of micro at pin sixthen immediately stops. By rotating the capstan manually we could get thePWM signal to come up for a few seconds. This enabled us to trace theproblem to a specific area. We found that PWM goes | ||
| Sony | CCDF30 | CAPACITOR DRIES OUT | Varying symptom and intermittent. Picture is fuzzy like bador dirty V. head. Playback in slow mode (LP), like servo (ATF) problem.Sometimes when unit is cold, there is no picture. I've encountered thisproblem at least three times with PCB replacement. | ||
| Sony | CCDF301 | NO PICTURE IN VIEWFINDER | Viewfinder picture initially is normal. Abruptly changed toexcessive brightness with complete loss of video. Found apparent internalheater cathode short in CRT. |
