| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Sony | STRGX80ES | UNIT INOPERABLE AND VIDEO MONITOR LED ONLY IS ON | Unit is inoperable with no display, no sound and only videomonitor orange LED is on. | ||
| Sony | TCFX410R | NO AUDIO | No audio. | ||
| 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 | TCW235 | UNIT WILL NOT GO TO SYNCRO DUBBING MODE | 1. Play on A deck, sound is muted. 2. Play on B deck, soundis ok. 3. Syncro dubbing mode, high or normal speed mode, B deck will notrun. IC-701, 702 and 703 had been replaced by SSC technician. | ||
| Sony | SLHF550 | L-CH WILL NOT WORK PROPERLY ON BETA-HIFI | 1. No L-CH on pre-recorded tape. 2. Distorted L-CH on self-recorded tape (and low level). This seems to be easy because you can com-pare with L-CH and R-CH. IC-1 had been changed by SSC technician. Check-ed DC voltage and waveform is same on L and R. | ||
| Sony | EVC3 | WILL ONLY PLAY IN B/W | Barely perceptible signal on Playback of known good tape.Determine normal RF, normal video at input to CC-24 board. Essentiallyno output, indicates no bias pins 4 and 10 IC-001. | ||
| Sony | CCDF77 | SNOWY PICTURE | One field is extremely low and noisy on all tapes. Tracedproblem to defective RP-77 board. After replacing RP-77 board itstill had some snow. Replaced upper drum assembly A-7049-306-A. | ||
| Sony | CCDF401 | PICTURE IS BLURRY | One field is missing. No improvement with head cleaning andabsolutely no RF envelope on missing field. IC-101 pin 29 does not passnoies input, RF SWP is present. Determine problem in RP-77 board. | ||
| Sony | CCDF34 | WILL NOT EJECT TAPE | RM-95 indicates loading fault. Manually released tray andfound that the back tension arm was causing the mechanism to jam. It wascaught on the wrong side of the guide pin in the left loading track. | ||
| Sony | CCDTR6 | NO PICTURE IN CAMERA MODE | No camera picture, iris failing to open and all other func-tions are normal. Confirm iris cannot be opened manually. Disassembleiris and determine substantial lubricant on lower tip of iris blade. | ||
| Sony | CCDTR5 | CAUTION LIGHT COMES ON DURING REWIND | Noisy erratic rewind because the tape became slack in the tapepath. The RM95 displayed 00.03 service mode error. No error was shownduring unthreading. Determine multiple damaged teeth on arm assemblygear. Installed No. 256, 264, 207 and 206. This re | ||
| Sony | CCDF56 | NOT SHARP VIEW OR FOCUS | Chroma only, little or no luminance, playback normal. CameraY appeared normal entering IC-401, but no output. Determined IC-401 isdefective. | ||
| Sony | CCDF401 | NO IMAGE IN VIEWFINDER | Camera picture is normal, distorted viewfinder raster on videoand found incorrect drive frequencies which indicated a defective IC-901. | ||
| 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. | ||
| Sony | SLV353UC | SHUTS DOWN IN PLAY AND WON'T ACCEPT TAPE | Unit would shut down, traced problem to defective cam gear. |
