| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Sony | KV32SR10 ANU-2 | raster | KV32SR10 Unit has dark raster with flaring across the picture. | Measuring the G2 voltage at 1000 vdc source for the G2 only finds 62 volts. R519 is open. Replacing R519 a 2.2K resistor & D501. | Muller |
| Sony | KP41EXR96 ANU-1 | dead | Sony ANU-1 chassis. Unit has defective horizontal output transistor | Apparently nothing else is damaged with this chassis. However if the horizontal output is shorted after several hours of operation. Unit has defective horizontal driver transformer and driver transistor. Leads on driver transformer show signs of oxidation | Muller |
| Sony | KV27HSR10 ANU1 | RASTER | Unit has intermittent raster. Bringing up the G2 voltage stops the intermittent action of the CRT | REMOVE THE FOLLOWING PARTS ON THE C-BOARD. R754 RESISTOR, 10K OHM, C719 CAPACITOR, ELECTROLYTIC 22NF/25V, R755 RESISTOR, 5MM JUMPER, 330 OHM. CONFIRM AND READJUST THE G2 FOR CORRECT WHITE BALANCE. | Muller |
| Sony | KV32XBR50 ANU1 | No Highvoltage | Sony KV32XBR50 . No high voltage,. Has sound. Tech claims all B+'s are normal from power supply however no high voltage. | B+ OK on Horizontal output but not OK on Horizontal Driver. No B+ on driver. Tech found small connection loose on primary connection of driver transformer. Resoldered and restored normal operation. | Muller |
| Sony | KV32XBR10 ANU1 | no audio | KV32XBR10 Unit has no audio | Product has a defective MTS audio controller part # 8-741592-2 (8-741-100-56) original number SBX1592-02 corrected the symptom | Muller |
| Sony | KV32XBR51 ANU1 | intermittent raster | KV32XBR51Unit has intermittent symptom of no raster. Has sound and high voltage. | Further visual checks in the television discover the filaments become dim intermittently. More visual inspection reveals many small ""ring"" fractures around the heater pins of the flyback transformer. "" | Muller |
| Sony | KV27XBR15 ANU1 | dead | Sony KV27XBR15 ANU-1 chassis Unit is dead. Unit had all 3 regulators loose. All had ring fractures. Once resoldered the set still did not turn on because of a short to ground on the 135 vdc line. | Horizontal output is also shorted. ?This unit requires a modification to the horizontal output section KIT # T-998-56641. This Kit consists of a 2SC4927 and a .68 ohm resistor that must be used in the emitter of the horizontal output transistor. | Muller |
| Sony | KV32XBR10 ANU1 | AUDIO | Unit has no audio | 8-741-592-2 (8-741-100-56) original number SBX1592-02 corrected the symptom | Muller |
| Sony | KV27TS20 ANU | vertical | KV27TS20 Unit has highly intermittent vertical foldover mostly at the top of the screen | Unit had small ring fractures around the vertical deflection yoke connector pins on the chassis. Resoldering the connections corrected the symptom | Muller |
| Sony | KV32V26 AA3 | green retrace lines | Sony KV32V26 serial 8012582 Goes to green retrace lines and then shuts down. When it comes back on again the unit will be in the video input mode. | The CRT # is A80JYV51X . The cathode voltages at red and blue cathodes are 156 but the green cathode is 22. When the socket is disconnected the green cathode supply jumps to 153 vdc. The CRT is defective. | Muller |
| Sony | KV36XBR250 AA-2W | GEOMETRY | KV36XBR250 This television has as symptom on the screen where a small area has a non linear horizontal area that causes the image to expand when the image passes through this area. The area about 1/2 inch wide and effect the entire frame of the picture. It can be seen if characters are scrolling through the screen. | Tech needs to change the value of C553 from .33 @ 200 vdc to .47 @ 250 vdc part number 1-117-667-71. This improve the linearity in that are of the screen | Muller |
| Sony | KV36XBR250 AA-2W | 16X9 mode | Customers DVD player always plays back in 16X9 mode. Customer has JVC DVD player. Disc plays back in 16:9 customer selects 4X3 mode on their DVD player but TV stills displays 16X9. The JVC DVD player puts out ID signal even when no 16X9 is available. When the Sony TV detects this special ID signal it automatically puts the TV in to the 16X9 mode. Compression Mode. Customer must now select modes manually on their DVD player. | This auto feature can be turned off but only in the Service Mode. Change ID7 from 9 to 8. This is the No Auto V. Customer must now select modes manually on their DVD player. | Muller |
| Sony | KV36XBR200 AA-2H | VERTICAL SWEEP | KV36XBR200 serial 9015396. Unit has insufficient vertical sweep. Also has top vertical foldover. Tech can get into the menu and effectively move the vertical height and centering but it will not illuminate the foldover condition | Tech needs to replace IC561, D561, & C565 | Muller |
| Sony | KV36XBR20 0 AA-2H | vertical | Unit has insufficient vertical sweep. Also has top vertical foldover. Tech can get into the menu and effectively move the vertical height and centering but it will not eliminate the foldover condition. | Tech needs to replace IC561, D561, & C565. Unit had defective Pump up capacitor. C565 | Muller |
| Sony | KV36XBR200 AA-2H | SCREEN TEMPERATURE | KV36XBR200 serial 9016329. On the far extreme left and right side of the screen the picture has a yellow color temperature where it should be white. | When looking at a blue raster at 60 IRE the blue does not have uniform brightness across the screen. The light output is not the same level at the area of the screen where we see the yellow with a 60 IRE white screen. We are not able to adjust the Blue to make it equal in brightness in all areas of the screen.. This is a defective CRT. Customer does not want the set requesting a replacement. Under 30 day | Muller |
