Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
---|---|---|---|---|---|
Sony | CDP70 | NO DISC ROTATION - PART MISSING | Part missing on chucking arm assy. Nowhere to be found inunit, with part missing chucking arm puts too much pressure on disccausing no rotation. | ||
Sony | CDP70 | NO SLED OPERATION | Sled motor would not run. | ||
Sony | CDP70 | UNIT WOULD NOT PLAY ENTIRE DISC | Unit will not track through disc. | ||
Sony | CDP701ES | NOISE IN R CH | R-ch sounded very noisy. Sounded like Ju-Ju. | ||
Sony | KP7220 | ERRATIC TUNING AND DISTORTED PICTURE, REPLACED R547, R546 | Picture is dark and shrunken in on sides, will not staytuned on channel selected. Tuning is erratic. | ||
Sony | STP7J | MALFUNCTIONING MEMORY CHIP | This unit worked fine except it was not possible to enter astation into memory. All inputs to the memory appeared to be correct.Replacing IC601 (CX761) resolved the problem. | ||
Sony | CDP701ES | REMOVAL OF SHORTING CLIP | Even though new OPB was installed, unit did not operate. | ||
Sony | CDP701ES | CHUCKING MOTOR SWITCH NOT ENGAGED | The unit rejected the disc intermittently. Opened the unitand found the chucking operation was not done, when we closed the disctable. | ||
Sony | TAP7F | REPLACEMENT XSISTOR LEADS TOO SHORT | National Parts Center is substituting 2SA1141 for 2SA1097and 2SC2681 for 2SC2571. The substitute transistors have leads that aretoo short. | ||
Sony | CDP701ES | RF PLL AND CLV PLL OUT OF ADJUSTMENT | Unit will not track discs with visible defect in program area.Some discs track on CDP-101 and CDP-200 with no problem. Possible causeof this could be the AUTO ANTISKATE circuit in the CDP-400 and CDP-701ES. -HQ COMMENTS: Careful electrical alignment, p | ||
Sony | STP75 | DEFECTIVE CONTROL UPC - IC603 | This unit did not light any display segments and there wasno tuning. A check of - control uPC - IC603 revealed that the IC wasinoperative. | ||
Sony | CDP701ES | DEAD UNIT | The dead unit had IC108, IC109, IC110, IC801 - shorted.IC108 was physically melted, with a hole in the chip. We can duplicatethe problem by shooting C218, C214, C138 to ground for a fraction ofa second. | ||
Sony | KP7220 | NO BLUE, REPLACED CRT AND D5320 | The stopper diode associated with the blue CRT was shortingout about every 30-60 days. We found the problem to be caused by adefective CRT. The CRT was intermittently shorting. Evidently when alarge enough arc occurred the associated transient would d | ||
Sony | KP7220 | FAINT CROSS HATCH ON THE SCREEN, REPLACED D303 | This unit had a faint cross hatch superimposed on picture. | ||
Sony | KP7225 | UNABLE BLUE HORIZONTAL CONVERGENCE, REPLACED Q5353 | Blue horizontal convergence control inoperative. |
