Sony | KV2680R | NO PIX, NO SOUND, LEAKY C-104 REPLACED | Unit when turned on would come up with high voltage but nosound, no picture and no control from front panel of any function. FoundC104 reading 150 Ohms on Pin 15 of IC105. This capacitor caused no Mclock on Pin 25 of IC103. | ||
Sony | KV2680R | SET COMES ON BUT NO OTHER FUNCTIONS, SNOWY SCREEN, OPEN D031 | Set could be turned on or off. Raster with snow was presentand no other functions would respond other than on/off. Inspectionrevealed no clock pulses at Pin 16, IC031. Voltage check showed no DCvoltage at Pin 1 or 41 of this IC. I found D039 to be op | ||
Sony | KV2680R | NO CHANNEL CHANGE, IC-1302 ON "A" BOARD | Unit would not change channels. If channel up/down waspressed, screen would blank for a moment, and return to the same channel. | ||
Sony | KV2680R | NO PICTURE AND NO SOUND, C-140 ON "A" BOARD | Problem was no picture and no sound. ASC hooked up thisKV-2680R P3 chassis to his RCA test jig model 10J106A using Telematicadaptor 10J733 (Color TV S/B #212). | ||
Sony | KV2680R | NO SOUND/PIX, COLD SOLDER ON 12V RECTIFIER D-506 | This unit had no sound or picture. | ||
Sony | KV2680R | NO AUDIO, REPLACE IC1107 AND ADD CAPACITORS/DIODE | The customer informed me that just before the sound went bad,they heard a loud snapping noise. I feel when the set is new and thetube snaps during its breaks in period, causes the IC1107 to become defec-tive. -HQ COMMENTS: To protect IC1107 from static | ||
Sony | KV2680R | NO FUNCTIONS WHEN HOT, REPLACED LEAKY D-041 ON "X" BOARD | After turn on, all remote control functions were inoperative,plus manual controls. Also the problem would occur about 2 min afterturn on. Heat and cold had no bearing on this unit. | ||
Sony | KV2680R | RASTER BUT NO AUDIO/VIDEO, IC1109 SHORTED ON "X" BOARD | Unit had raster out, no video nor audio, and R1247 wouldshort out at turn on. | ||
Sony | KV2680R | AUDIO EXISTS AT VOL ZERO, REPLACE IC-1107 | When the audio level is turned all the way down, you canstill hear audio. | ||
Sony | KV2680R | NO FUNCTIONS EXCEPT POWER ON, IC-103 | No remote control functions, no channel change, volume change,color change or any control available at the receiver manually exceptpower on. | ||
Sony | KV2680R | NO AUDIO/VIDEO, REPLACE 15V REG DRIVE Q-1128 | Unit had raster out no video or audio. | ||
Sony | KV2680R | INTERMITTENT SHUT OFF, COLD SOLDER ON C-1182 | Power relay would intermittently begin to chatter and setwould lose raster and audio. The 18.9 volt line would drop to approx.14 volts when this happens. Found one leg of filter C1182 had a coldsolder connection. | ||
Sony | KV2680R | NO VIP OR TIMER FUNCTION, V SIZE ADJ CURED VIP | Intermittent VIP, sometimes no VIP function at all. | ||
Sony | KV2680R | DEAD SET, DEF H DRIVE T-501 CAUSING DAMAGES | The unit came in with a shorted horiz. output transistor anddefective B+ regulator package. We found the problem to be caused by adefective horiz. drive transformer. The primary was shorted. | ||
Sony | KV2680R | P/N INQUIRY FOR CRT, 8-735-453-05 SUB TO 8-735-453-05 | P/N for KV-2681 CRT is incorrect. -HQ COMMENTS: The part # in S/M 8-735-453-05 is correct and correspondsto A67JHG01X type CRT. In the near future, it will be supplied as areplacement part in sets specifying this CRT.PART NUMBER LANDIN |
