Sony | EVS7000 | NO DISPLAY - REPLCE OPEN R208/100K ON FM16 BOARD | No display. | ||
Sony | EVS5000 | CLOCK GAINED SEVERAL SECS A DAY - ADJUST CLOCK FREQUENCY | The clock gained several seconds a day. | ||
Sony | KV32XBR45 | NO VIDEO ON MAIN PICTURE, RESOLDER Q421 ON UA BOARD | No vidoe on main display but PIP video was ok. Check videoat pin 47 IC402 it was ok. Pin 40 video out of IC402 has no video,replaced IC but, still no video. Check followed this line to Q421and found collector has not enough solder to PC board. | ||
Sony | KV32XBR45 | NO VERTICAL DUE TO NO 5V DC SUPPLY TO MICRO, REPLACE D613 | Unit came in with no picture or sound. Discovered that itdid not have vertical deflection. All data lines were low. Between 3and 3.6V p-p. Nothing was loading them down. Found shorted diode D613on open resistors R623, 624 and 625 in 5V set line. | ||
Sony | KV32XBR37 | NO PICTURE, R701 | Customer complain of no picture, dark screen. Voltage checkon C board showed low G2 voltage on pin 5 of CRt socket. CN702 pin 1measured 1000v, resistance test of R701 showed open resistor. | ||
Sony | KV32XBR100 | INCOMPLETE MENU SCREEN, X BOARD | No channel display in screen and missing icons in left handside menu. Found X board popped out from PCB support clip and is causingpoor connection between CN5002 (X board) and CN7001 (A board).See servicee manual page 76 component side matrix A:1. S/N | ||
Sony | KV27XBR29 | POOR FOCUS ON EDGES, REMOVED SOLDER SPLASH | Unit had poor focus on edges. Was not possible to getuniform focus. Problem caused by a solder splash shorting quadrapoleoutput Q908 between collector and emitter. This also overheated L902. Itappears that the problem was present from the factory, n | ||
Sony | KV27V55 | NO PICTURE NO SOUND BUT HIGH VOLTAGE, IC301 | TV turns on but no picture and no sound, but has highvoltage. When increasing screen voltage (G2) you can see horizontal line. Vertical drive pulses missing from IC301 M Board. | ||
Sony | KV27S10 | INSUFFICIENT VERTICAL, YOKE | Picture pulled up about one inch from bottom. Adjustingcontrols allowed picture to fill out but centering was off. Whencentering was adjusted picture folded over. Replacement of yoke resolvedproblem. | ||
Sony | KP61XBR48 | CAN'T SWAP PIP AND MAIN PICTURE, CUSTOMER SETUP IN MENU | Customer complaint was he could not swap his PIP and mainpictures. Otherwise the PIP worked normally. | ||
Sony | KP46S55 | POOR CONVERGENCE, CRACKED CONNECTION "D" BOARD | Customer complained of poor blue registrations, notadjustable with customer control. | ||
Sony | KP41T15 | DEAD, SHORTED AUDIO OUTPUT IC | No power. Found power supply dead and shorted Audio output IC. Reported by Ted Kim, Kim's Electronics | ||
Sony | KP41T15 | DEAD, REPLACED D803 C808 AND R854 ON E BOARD | The unit has no power, check the power supply and high voltage. I found unit lost 200V. Reported by Ted Kim, Kim's Electronics. | ||
Sony | SPP2000 | ALTERNATE SOLUTION TO BATTERY CONTACT SPRING PROBLEM | Battery springs collapse causing intermittent operation. | ||
Sony | SPP1000 | MYSTERIOUS FAILURE, AC ADAPTER DEAD, NO OPERATION | Unknown case of multiple component failure. Samplesforwarded, AC adapter blown. -HQ COMMENTS: I examined the sample and noticed that D404 was eitherremoved or missing. Without this diode there is about 100 volts ofcounteremf generated by the line rel |
