---|---|---|---|---|---|
Sony | KV27HSR10 | PICTURE STRETCHED - TOO MUCH VERTICAL SIZE , REPLACED IC-500 | Picture looked ok except that channel display is above topedge of picture. When set is put in service mode, adjusting VSIZ lineand VPOS made picture ok. Customer had a second set and these settingswere quite a ways off. For example, V LIN setting is n | ||
Sony | KV27HSR10 | HORIZONTAL OUTPUT TRANSISTOR SHORTS OUT, REPLACE C-522 | Q-503 (horizontal output transistor) shorts out after beingreplaced (instantly). Disconnecting Q-503 collector restores 137V line.With the transistor in circuit the line goes to 0VDC. | ||
Sony | KV27HSR10 | WIGGLY PICTURE, REPLACED IC-301 ("A" BOARD) | Wiggly picture as if horizontal interlacing scan lines wereslightly off time. Horizontal output sine wave looked clean on oscilos-cope, DC sources had no ripple. When scoping (applying color bar genera-tor with chroma removed), IC-301 pins 3 and 5 luma | ||
Sony | KV27HSR10 | HORIZONTAL CENTERING: SERVICE MANUAL PROCEDURE, SEE SB 102 | The horizontal centering adjustment on page 30 of the servicemanual omits the fact that a horizontal centering tap exists as shown onpage 36, the F board. If the remote commander adjustment is made withthe tap in the wrong place, some sets will exhibit | ||
Sony | KV27HSR10 | ANODE CONNECTOR MISSING, REPLACE FLYBACK | When replacing the A board, the anode wire from the flybackis missing. Is there a part number for it? -HQ COMMENTS: Please disregard the flyback that might come on the re-placement board. Reinstall either a new flyback or the one from the oldboard. | ||
Sony | KV27HSR10 | NO HORIZONTAL PINCUSHION CORRECTION, CRACK NEAR FBT/PIN 11 | Pincushion adjustment inoperative L-501, R-571, Q-505, etc.checked ok. DC voltages on IC-531 ok. Replacement of IC-531 did notchange condition. | ||
Sony | KV27HSR10 | SET GOES INTO OVP INTERMITTENTLY ON TURN ON, Q0651 OPEN | Set goes into OVP intermittently on turn on (every 4 or 5times). When unit works, all voltages are correct. | ||
Sony | KV27HSR10 | LOUD HIGH PITCHED NOISE FROM SET, GLUED SHIELD ON T-602 | Loud, high pitched noise from set and is not in audio circuit.Sounds similar to yoke with singing problem. Before replacing yoke pleaseread. | ||
Sony | KV27HSR10 | HORIZONTAL RGB LINES IN TOP PORTION OF PIX., REPLACED R-517 | Unit looks normal but, displays red, green and blue horizontallines on the top portion of the picture. Normally, adjusting the REFfunction in the service mode will shift the lines out of the picture area.However, in this case the shift was not enough. | ||
Sony | KV27HSR10 | PINCUSHION DISTORTION, COLD SOLDER JOINT AT DAMPER CIRCUIT | No horizontal pincushion correction occurring. As received,set had overheated and open L-501, open R-571 and shorted Q-505. Afterreplacing these, set would work normally for about 30 seconds. Q-505would short, R-571 would open sometimes L-501 would op | ||
Sony | KV27HSR10 | "X" BOARD PART NUMBER, 8-752-035-54 | People order part number 1-629-624-11 ( X board) when theyreally need part number 8-752-035-54 (IC-251). This generates customercomplaints because 1-629-624-11 is a blank board. since this is not wantthe servicer needs the servicer has to reorder the c | ||
Sony | KV27HSR10 | DEAD, REPLACED FBT, R-571 AND Q-505 | The unit came in with a shorted HDT. A new replacement wasimmediately burnt out. | ||
Sony | KV27HSR10 | IK BLANKS RGB OUTPUT FROM IC-301, REPLACED CRT | There was no picture or characters displayed. Sound was okand the remote appeared to function. We found that there was no RGBoutput from the jungle IC (IC-301). Pin 27 of the jungle (IC-301) was0.V. We suspected the problem to be caused by the IK (ca | ||
Sony | KV27HSR10 | NO CONTROL OF SOUND VOLUME, REPLACE IC-251 MTS DECODER | Unit displayed multiple audio problems. Volume on screendisplay operated normally but, the actual sound level was stuck atapprox. half volume. When the audio level was changed nothing would occuruntil the channels were changed. | ||
Sony | KV27HSR10 | SINGING YOKE, REPLACED YOKE. SEE SERVICE BULLETIN 114 | Replaced singing yoke. -HQ COMMENTS: Please refer to TVP Service Bulletin number 114. NewYoke Part Number is 1-451-275-41. |
