|---|---|---|---|---|---|
| Sony | XR6180 | TAPE DECK WILL NOT FUNCTION OR WILL FUNCTION INCORRECTLY | Have seen several units so far where both Q-405 and the AMSplunger were defective. The plunger was actually melted. I am unsurewhether the plunger or the drive transistor originally caused theproblem. | ||
| Sony | SLHFT7 | POPPING IN BETA HIFI | Popping sound in beta hifi. | ||
| Sony | SLHF1000 | NO BETA HI-FI RECORD | No Beta Hi-Fi Record. Playback or pre-recorded material ok.All voltages ok on IC-004. Missing switching voltages at pin 44 IC-003.Found open foil between Q-610 and D-606. Simulated shorted transistor. | ||
| Sony | KPR46DX10 | SNOWY PICTURE ON MAIN SCREEN WHEN IN AUX, CUSTOMERS FAULT | Customer was complaining that when they hit Aux they only hadpicture on the child screen, with snow on the parent screen. -HQ COMMENTS: Found that they were using a VCR, and cable box in linewith the Converter and Aux. terminals. With the VCR connecte | ||
| Sony | DTC75ES | TEST TAPE TY7252 | Recommended test equipment list for DAT specifies a TY7251test tape for tracking. DTC-75ES manual calls for a TY7252. Are theyinterchangeable? -HQ COMMENTS: I will have to check with Tokyo. I suspect that there isa typo in the DTC-75ES service manual | ||
| Sony | SPP320 | INTERMITTENT RINGING | The Handset would only ring sometimes. In addition, theHandset would intermittently not beep when keys were pressed. Flexing theHandset Main PCB would cause the ringer to function. | ||
| Sony | CCDF70 | INCORRECT SLOW MOTION OPERATION | Slow motion operation erratic. | ||
| Sony | KV2726R | SET IN SLEEP MODE AT TURN-ON, REPLACE IC-101 CONTROLLER | When set was turned on, it was in the sleep mode per non-authorized servicer. After several checks, found pin 15 of IC-102(memory) to read zero volts. Isolated pin 15 and 5 volts would appear onthe 5 volt line. All other readings were good. With pin | ||
| Sony | FD2A | PICTURE LOOKS OUT OF FOCUS, REPLACED C555 | Picture appears as raster only, out of focus. In reality, thesweep is displaced far above the top of the tube due to DC level upsetcaused by shorted C-555. | ||
| Sony | FD10A | NO HORIZONTAL SYNC, REPLACED C506 | No horizontal sync. OV at pins 17 and 18 of IC-501 causingphase detector inoperation due to shorted C-506 (pin 15, also 0 volts). | ||
| Sony | TAM50 | UNIT DEAD, DOES NOT RESPOND TO ANY BUTTON - ALL LIGHTS OFF | Unit is dead. Does not respond to any button. None of thelights turn on and no beep is heard.The micro IC-3 had all the right voltages, except for IC-3/pin 8 which waslow instead of high. Found that the TIME STAMP IC-10 had no supplyvoltage. | ||
| Sony | CCDTR5 | DEW AND REC (VTR) LIGHT STAYS ON, CAMERA VIDEO FLICKERS | Dew light and VTR REC light stays on and camera videoflickers. DEW and VTR REC light do not affect VTR functions. | ||
| Sony | KV2780R | NO PINCUSHION, REPLACE R-1514 | Unit had no pincushion correction. Collector of Q-1501 had DCbut, no waveshape. There was signal present at pin 3 of IC-1502 and atone side of R-1514. | ||
| Sony | KV27HFR | VERTICAL ROLLING OF PICTURE, REPLACE R-527 | Checked the signal of IC-301 pins 47 and 48 found the synclevel at pin 48 was rounded off. Checked surounding components and foundR-527 had increased in value. I also checked C-520. | ||
| Sony | CFSW303 | WRONG PART NUMBERS IN MANUAL FOR MOTORS | The service manual has the wrong part numbers for the twomotors M-471 and M-481. The correct number for M-471 (deck B motor) hasbeen verified, but not for M-481 (deck A). The error seems to be only inthe later service manual which contains the AEP mode |
