KV2726R
|
Set in sleep mode at turn-on, replace ic-101 controller | When set was turned on, it was in the sleep mode per non-authorized servicer. after several checks, found pin 15 of ic-102(memory) to read zero volts. isolated pin 15 and 5 volts would appear onthe 5 volt line. all other readings were good. with pin | ||

FD2A
|
Picture looks out of focus, replaced c555 | Picture appears as raster only, out of focus. in reality, thesweep is displaced far above the top of the tube due to dc level upsetcaused by shorted c-555. | ||
| SONY |
FD10A
|
No horizontal sync, replaced c506 | No horizontal sync. ov at pins 17 and 18 of ic-501 causingphase detector inoperation due to shorted c-506 (pin 15, also 0 volts). | ||

TAM50
|
Unit dead, does not respond to any button - all lights off | Unit is dead. does not respond to any button. none of thelights turn on and no beep is heard.the micro ic-3 had all the right voltages, except for ic-3/pin 8 which waslow instead of high. found that the time stamp ic-10 had no supplyvoltage. | ||

KV2780R
|
No pincushion, replace r-1514 | Unit had no pincushion correction. collector of q-1501 had dcbut, no waveshape. there was signal present at pin 3 of ic-1502 and atone side of r-1514. | ||
| SONY |
KV27HFR
|
Vertical rolling of picture, replace r-527 | Checked the signal of ic-301 pins 47 and 48 found the synclevel at pin 48 was rounded off. checked surounding components and foundr-527 had increased in value. i also checked c-520. | ||

Wrong part numbers in manual for motors | The service manual has the wrong part numbers for the twomotors m-471 and m-481. the correct number for m-471 (deck b motor) hasbeen verified, but not for m-481 (deck a). the error seems to be only inthe later service manual which contains the aep mode | ||

STRAV910
|
Error in schematic and parts list for q-721 | The schematic and the parts list show this transistor as apnp, 2sa1841. in reality this is a npn, 2sc-1841 in the set. please explain is this an error and should a correction be made? -hq comments: the service manual has a misprint. if you reference | ||

KV27TS22
|
Intermittent video blanking, replace reg ic-601 | As the ac line voltage would fluctualte, the video wouldbecome blanked out in an area that would vary in size and shape. the135vdc line never increased over 117vdc. note: the blanked portions ofthe video would take weird sizes and shapes. | ||

KPR4600B
|
No last channel memory at turn on, replaced q-308 and d-339 | No last channel memory at turn on. also the set wouldintermittently come on with a de-tuned picture or possibly a weirdcombination of numbers in the channel display area. we noted the resetvoltage to pin 7, ic-001 on m board never got over 1.5vdc and a | ||
