Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
---|---|---|---|---|---|
Sony | UP811 | MULTIPLE PICTURE (REPEATS HORIZONTALLY) | The unit prints about the first 1/3 of the picture insuccession from left to right - creating a tripple image effect. | ||
Sony | D15 | NO CHARGE OF BATTERY | Battery would not charge. Charging circuit inoperative.Found R-403 incorrectly located on the board and soldered to the collectorof Q-433. | ||
Sony | CPD1303 | VERTICAL FOLD AT TOP OF SCREEN | Vertical fold at top of screen. 80 volt measured on 15 volts.T-654 secondary open. | ||
Sony | CPD1302 | VERTICAL FOLD AT TOP OF SCREEN | Vertical fold at top of screen. 80 volt measured on 15 volts.T-654 secondary open. | ||
Sony | CCDV220 | INTERMITTENT VIDEO DROPOUT | Intermittent dropout in playback picture. | ||
Sony | TAAX520 | MALFUNCTIONING VOLUME CONTROL | Volume control operation was erratic. LEDs did not operatesmoothly - audio was choppy. Replaced IC-202 w/ new IC, but when poweredup all but 1 LED was on and volume controls (+ and -) had no effect. | ||
Sony | TAAX335 | PART NUMBER CORRECTION | Part number is not listed in Kansas City. | ||
Sony | CCDF40 | NO POWER | No power, no LED display and no functions. (Ever 5V) measured1.3VDC. Lift IC-191/2 and +5VDC restored. | ||
Sony | CCDF40 | NO PICTURE IN CAMERA MODE | Camera has no picture display. | ||
Sony | KV1510 | HORIZONTAL OSCILLATOR NOT RUNNING | Dead set. Minimal current being drawn from regulated powersupply. Vcc present at horizontal output transistor, but horizontaloscillator not running. Externally power horizontal oscillator, and bringset up on variac set works ok. | ||
Sony | KV2657R | POOR TUNING ACTION - TUNING DRIFTS AFTER TIME, IC602 | Critical tuning and drift after time. Voltages at TP02 andTP03 on the (M) board were very high, about 49V. 33V supply read 43.0V.Q-604 on the (F) board not operating. Measured voltages and found IC-602inoperative ..... open device. | ||
Sony | KV1926R | WEAK AFT LOCK, REPLACED PRESCALER | Weak AFT lock when changing channels. Intermittent and notaffected by heat, cold or vibration. Unit would also detune after playingfor sometime. Data signal at prescaler would change with drift. | ||
Sony | STRAV1000 | INTERMITTENT AUDIO LOSS - INTERMITTENT PROTECT ACTIVATION | If protect mode activates, approximately 3 VDC present atoutput of one or both power amps. Intermittent loss of audio, usuallyleft channel. Intermittent activation of protect circuit. These symptomsare independent of each other. Intermittent connecto | ||
Sony | STRAV900 | INTERMITTENT AUDIO LOSS - INTERMITTENT PROTECT ACTIVATION | If protect mode activates, approximately 3 VDC present atoutput of one or both power amps. Intermittent loss of audio, usuallyleft channel. Intermittent activation of protect circuit. These symptomsare independent of each other. Intermittent connecto | ||
Sony | TCV7 | CHATTERING SOUND FROM MECHANISM | Chattering sound from mechanism, primarily in pause mode. |
