|---|---|---|---|---|---|
| Sony | SPP85 | NO HANDSET TRANSMIT - REPLACE D-551, P/N 8-719-949-46 | The handset would not transmit. I checked IC651 (PLL) and itwas operating properly. I checked pin 1 of IC551 and found no frequency.In addition, D551 was open. | ||
| Sony | SPP75 | NO POWER LED - REFLOW R-260 | No power LED. Unit worked fine, but the power LED did notlight. I found R260 cold soldered. | ||
| Sony | SPP85 | NO POWER LED - REFLOW R-260 | There was no power LED, the unit worked fine but the power LEDdid not light. I found R260 cold soldered. | ||
| Sony | SPP95 | NO POWER LED - REFLOW R-260 | No power LED, the unit worked fine, but the power LED did notlight. I found R260 cold solered. | ||
| Sony | SPPA60 | UNIT REPEATEDLY SEIZED AND RELEASED LINE - REPLACE C-46. | The unit would repeatedly seize and release the line. I foundC46 was leaking. | ||
| Sony | SPP95 | NO HANDSET TRANSMIT - L553 POPPED THROUGH BOARD | Handset was not putting out any transmit signal. L553 waspopped through the board and did not allow for oscillation. | ||
| Sony | SPP85 | NO HANDSET TRANSMIT - L-553 POPPED THROUGH BOARD | The handset was not putting out any transmit signal. As itturns out, L553 was popped through the board wich did not allow foroscillation. | ||
| Sony | SPPA20 | HANDSET TRANSMIT FREQUENCY IS LOW - REPLACE X501 (157976811) | X501 is defective because it prevents IC501 (PLL) fromoperating properly. X501 is producing a low amplitude which is notsufficient to correctly run IC501 (PLL). In addition, it prevents the TXfrequency from being adjusted to the correct frequency. | ||
| Sony | SPP95 | NO BASE TRANSMIT - REPLACE IC-151, P/N 8-759-824-20 | I found the base unable to transmit. I checked the Q253collector and found 1v. I lifted pin 17 of IC151 (VCC) and checked Q253again and found voltage to return to 3v. | ||
| Sony | SPP95 | NO HANDSET TRANSMIT OR TX FREQUENCY HIGH OR LOW - IC-651 | I found the handset unable to transmit. I checked thevoltage at pin 4 of IC652 and found 1v. Then I lifted pin 17 of IC651(VCC) and checked pin 4 of IC652 again and found voltage returned to 3v.Also in other units, I found IC-651 defective, which preven | ||
| Sony | SPP95 | HANDSET TRANSMIT FREQUENCY HIGH OR LOW - REPLACE X-651 | X651 is defective preventing the adjustment of the handsettransmit frequency. The TX frequency can be either high or low. I haveseen many of both circumstances. | ||
| Sony | SPPA40 | HANDSET TRANSMIT FREQUENCY IS LOW - REPLACE X501 (157976811) | X501 is defective, preventing IC501 (PLL) from operatingproperly. X501 is producing a low amplitude which is not sufficient tocorrectly run IC501 (PLL). This also prevents the TX frequency from beingadjusted to the correct frequency. | ||
| Sony | MDP333 | NOISY VID/AUD AT END OF DISC: FOP FLEX CABLE 157464811 (168) | On the twelve inch disc, the unit will skip and exhibit bothvideo and audio noise only at the end of the disc. | ||
| Sony | STRAV1020 | WITH POWER ON, DISPLAY SHOWS DRLC, L501 FAULTY, 1-410-521-11 | This is the second time the unit has been in with the sameproblem. Last time, I replaced the system control IC502 and it came backafter a month. After the power is on, nothing works except the DRLCdisplay. | ||
| Sony | KV27TS25 | NO PICTURE, REPLACED L-516 | There is no picture, nor is there any raster. Also, the soundsometimes goes out. |
