| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Sony | KV32XBR55 | COULD NOT GET COLOR IN TV MODE, REPLACE IC-102 | Could not adjust color in TV mode but could in video mode. Ifyou hit menu, then return TV would shut off for two seconds and then comeback on. | ||
| Sony | KV27XBR65 | NO COLOR FOR FIRST FEW MINUTES, REPLACED X-301 | Parent picture had no color for first few minutes and thenwould normalize. Child picture normal with color. Osciloscope showedgood chroma signal at IC-301/pin 5 (Chroma-In). When scoping 3.58 os-cillator (X-301), found it to be intermittent. | ||
| Sony | KV19TS20 | NO PICTURE/NO SOUND, LEAKY C-501 | At turn on relay would click but no picture and no sound.135VDC B+ is ok. Scope indicated no horizontal drive on IC-301 pin 11, no3.50 osc. at pin 8 IC-301. 10.5VDC (VCC) at pin 4 IC-301 was very low,measured about 3VDC. Found leaky capacitor C-501. | ||
| Sony | CCDF40 | NO RECORD OR PLAYBACK (PAGE 107) | No Record or Playback. | ||
| Sony | CCDF40 | DISTORTION IN PICTURE (PAGE 115) | Distortion in picture. In Playback picture looks like tapeentrance out of adjustment also sound was distorted. | ||
| Sony | CDPC305 | SCRAPING SOUND WHILE DISC IS PLAYING | The chucking yoke scrapes against chucking arm while playingdisc. Pushing on left front side of disc table corrects this problem. | ||
| Sony | TCDD10 | LOW BATTERY INDICATOR ALWAYS ON, UNIT WON'T PLAY, FF OR REW | Unit indicates low battery, loads the tape, but does not play,REW or FF. However, the SCAN and search functions work ok. After sometroubleshooting, I found IC-507 pin 34 (low battery detect input) voltagewas correct as indicated in the schematic. | ||
| Sony | KV32XBR10 | BLANKED PICTURE, RESOLDER IC-500, IC-581, AND IC-582 | Have seen several ANU-1 sets with components mounted to theheatsink that have poor solder connections. | ||
| Sony | CPD1304 | PINCUSHION PROBLEM | Unit displayed pincushion problem. Vertical rays were presentat the base of Q-315 but DC voltages were wrong. Instead of 29 volts onthe base voltage was 2.11 volts. Waveforms at IC-303 were incorrect. | ||
| Sony | D202 | ELEC. ADJUSTMENTS DIFFICULT DUE TO LACK OF EXTENSION CABLES | Adjustment of this unit is difficult due to mounting of themain board and optical block. Are any extension cables available for FOPmain board connections or should we just build our own? -HQ COMMENTS: Extension cables would make the D202 one of the eas | ||
| Sony | CCDV220 | ERROR IN BLOCK DIAGRAM | Block diagram on pp. 42-43 shows DT-62: SH1, 2 and 3 signalsgoing to SP1, 2 and 3 respectively on IC-251. This is incorrect. Theschematic on page 107 is correct. It refers to SH1, 2 and 3 as Gate 3, 1and 2 on CP-21 bd (HIC251). The actual connections | ||
| Sony | CCDV220 | YELLOW PICTURE/NO BLUE IN EE PICTURE | Unit had yellow picture on EE and self-recorded tapes. Noblue was getting through. We checked R-Y and B-Y at W-201. Pin 28 and29, noticing that the B-Y signal was about 5 times greater in amplitudeand did not look like the R-Y. We then checked the SH | ||
| Sony | CCDV220 | VERTICAL (JAIL) BARS IN EE MODE | Unit manifested evenly spaced black vertical bars in EE pic-ture or self-recorded tape. | ||
| Sony | CCDF35 | TAPE IS STUCK INSIDE | Tape is stuck inside unit. | ||
| Sony | MDP510 | DIFFERENCES IN "SV-33" BOARD | This has a different SV-33 board in it. The maindifference, aside from some extra coils in the 5 volt bus is the additionof 0 resistor from pin 1 of IC-102* to C-127 in the focus Yvil circuits.The part number on the board itself is 1-630-095-14.
