| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Sony | KV27SXR10 | BRIGHTNESS FLUCTUATION,REPLACED CONNECTOR WIRE ASS'Y A16-C3 | When the connector A16-C3 was wiggled at the A16 end,brightness would change. Reversing the cable (6 pin) showed no problem atthe C3 end but confirmed the problem was with the cable. | ||
| Sony | KV27SXR10 | VERY BRIGHT PICTURE/ REPLACED IC201 | External video signal makes picture too bright. | ||
| Sony | KV27SXR10 | PICTURE WOULD GO DARK, RESOLDERED RELAY PINS | Picture would go dark tap on set and it would come backfound ring crack on delay modual. | ||
| Sony | KV27SXR10 | VERTICAL JITTER VCR PLAYBACK, REPLACE C-203 | Unit had vertical jitter on video input. With off the air TVsignal everything was ok. Traced problem to leaky C-203, couplingcapacitor to input of IC-201 pin 2. | ||
| Sony | KV27SXR10 | PINCUSHION DISTORTION, REPLACE C-1510 | Set in ASC shop several times for pincushion distortion.L-1507 always found open. No reason found. Finally confirmed C-1510intermittently opening. | ||
| Sony | KV27SXR10 | UNIT COMES ON INTERMITTENTLY, RESOLDER T-651 | Unit would not come on intermittently i.e. no sound, noraster. Moving set slightly it will come on/go off by itself. Noted no135Vdc whenever problem occurred. Checked power supply on G bd., sawthere was no DC voltage at collector of Q-651. Resistance | ||
| Sony | KV27SXR10 | INSUFFICIENT V SWEEP/SEVERE FOLDOVER ACROSS SCREEN, C-1548 | Insufficient vertical sweep and severe foldover across thecenter of the screen. Most waveforms displayed distortion. By bridgingthis capacitor with another capacitor, the problem cleared. This C-1548was neither shorted or open. | ||
| Sony | KV27SXR10 | CLOCK LOSES MEMORY, AC LINE FAILURE RELATED | Intermittently, clock will zero out time will reset to :00.Also occured on serial number 7271746. The sample at servicer's will soonbe ready for examination by Zone or Technical Department. -HQ COMMENTS: Pin 27/IC-101 is reset pin also for clock operat | ||
| Sony | KV27SXR10 | NO ON SCREEN DISPLAY, REPLACE IC-107 | Unit had no on screen display. All other functions normal.IC-107 (5 volt regulator) output was 7 volts. | ||
| Sony | KV27SXR10 | HIGH PITCH SOUNDS, REPLACED YOKE SEE SB #0114 | High pitch squeal. | ||
| Sony | KV27SXR10 | TIME CLOCK TOO FAST, SEE SB TVP0087R1 | The time clock advances 12 minutes every hour. This indicates the microprocessor IC-101 is set to 50Hz. -HQ COMMENTS: This problem is caused by 50/60Hz misdetection. Please add a 0.1uf/50v cap between the base of Q105 and grou | ||
| Sony | KV27SXR10 | VERTICAL JUMP USING VCR, LEAKY C-1734 | There was a vertical jump in the picture using VCR playback. | ||
| Sony | KV27SXR10 | LINE ACROSS TOP OF SCREEN, AG HOLDER, NO SOLUTION | The outside tech in Costa Mesa informed me of customerscomplaining about the three band that hold the aperture grille fromoscillating. The problem is the customer can see the top line from adistance of 7 to 8 feet. The tech has been out to four custome | ||
| Sony | KV27SXR10 | CONVERGENCE PROBLEM, MAGNETS ADDED | When using cross-hatch pattern from NTSC generator, thebottom line looks like this plus top line is like this. | ||
| Sony | KV27SXR10 | NO POWER, REPLACE HDT | Set would not come on. Traced Hor. OSC to base of drivetransistor, found no B+ on transistor collector. Primary side of drivetrnasformer opened. |
