| SONY | SL20 | Sub part for ic201 | S/m lists ic201 as m54543l (8-759-600-24). the ic that isinstalled in the four units i have inspected is lb1640 (8-759-801-60).the lb1640 ic is a 10 pin ic, and the m54543l is a 9 pin ic. are theseic -hq comments: either one may be used. when using t | ||
| SONY | XR747R | Part no problem in manual | Above part number not in system. looking at fiche i foundpart number a-3217-255-a as correct number for filter assy in xr-747r. -hq comments: the number from the microfiche is correct (a-3217-255-a).a service bulletin will be issued. | ||
| SONY | CCDV8AFU | Distorted camera output | Sample crystal changed oscillator frequency from 28.6mhz to5mhz after 10 minutes. | ||
| SONY | VTX1100R | Dc to dc converter runs extremely hot | Dc to dc converter runs extremely hot. this is the secondunit at same dealer location within 30 days. -hq comments: q112 failure is rather accidental and its replacementshould be sufficient. we can protect q112 by adding 33Ω 1/6w(1-247-795-00) resi | ||
| SONY | TAAX5 | Intermittent engagement of the speaker protection circuit | Intermittently the speaker protection circuit would engagewithout any apparent reason. we found that intermittently there would beapprox. 1v on pin 4 of ic401/protector. we traced the problem back toconductive glue found in the area of ry301. | ||
| SONY | HVC2800 | Horiz jitter/pulling | The picture would jitter horiz and pull in from the leftside. we found the output waveforms to be distorted around ic4/horiz out. | ||
| SONY | CCDV8AFU | Tape jams around drum during threading | When a new tape is inserted, and tape starts to thread, itjams around the drum assy. this happens because there is no excess tapewhich can be pulled out from take up reel. -hq comments: under normal operation, the tape is fast forwarded for afew second | ||

| SONY | KV1957R | Horiz. output transistor would get very hot, r522 replaced | Horizontal output transistor would get very hot and eventuallyfail. inspection revealed that r522 had increased in value. | ||
| SONY | KV1975R | Dead, replace q501, t501 and r522 | The unit would not power up. we found the problem to becaused by a shorted horiz. drive transistor. the horiz. drive transformerand collector resistor were also defective. while this is not an unusualproblem, it is interesting to note that these compo | ||
| SONY | CDP70 | Hiss in left and right channels | There was a hiss in both channels which was present in betweentracks and with the audio. we found the problem to be a dead x103 on thed/a converter -ic109. i was surprised that any audio at all was processedthrough the ic under this condition. this ap | ||
