Sony | KV32XBR15 | SET GOES INTO OVP INTERMITTENTLY ON TURN ON, REPLACED Q-651 | Set goes into OVP intermittently on turn on (every 4 or 5times). When unit works, all voltages are correct. | ||
Sony | KV32XBR15 | "F" BOARD CIRCUIT CORRECTION, SEE SERVICE BULLETIN 66R1 | There is a discrepancy in the F board schematic diagram.When the board is ordered, it comes with a softstart circuit consisting ofQ-604, R-610, R-616 and C-613. This circuit is not in the service manual. -HQ COMMENTS: There was a production change when | ||
Sony | KV32XBR15 | NO PICTURE AFTER REPLACING IC-102 (MEMORY CHIP) | After replacing IC-102 picture would blank. The same wouldoccur in the service mode. Thus, how do we adjust the unit if we can't seethe adjustments ? -HQ COMMENTS: Follow these simple steps: (Also see SB #99)1. Before replacing IC-102, chart down the ad | ||
Sony | KV32XBR15 | IC-101 DOES NOT MATCH PART NUMBER IN MANUAL, SEE SB # 92 | Above part number does not match with the part called for inthe service manual. -HQ COMMENTS: During production, the microprocessor was changed. Thesetwo ICs are not interchangeable. Please check to see what micro is beingused before ordering from KCP | ||
Sony | KV32XBR15 | AUDIO BALANCE WAS COMPLETELY TO THE RIGHT, REPLACED IC-102 | When set turned on, audio balance always was completely to theright. Reset balance and set was ok until power was turned off. Thenbalance was always to right on turn on. | ||
Sony | KV32XBR15 | LOUD HIGH PITCHED NOISE FROM SET, PUT SILICONE AROUND 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 | KV32XBR15 | 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 | KV32XBR15 | NO PICTURE SLEEP LIGHT ON, REPLACED C-500 | Set has high voltage. Sleep light is on, but set has nopicture. Found .7Vpp on pin 31 of IC-301 (should be 2 volts). Foundshorted C-500. -HQ COMMENTS: When C-500 (on pin 1 of IC-500) shorts, vertical drivesignal will be lost. With the loss of output s | ||
Sony | KV32XBR15 | PINCUSHION DISTORTION, REPLACED R571,L501,D512 COLD SOLDERED | 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 | KV32XBR15 | NO PIX, OR SOUND, COLD SOLDER JOINT ON T-501 HDT, | Bad solder around T-501 HDT, caused the loss of Hor sweep andno raster resulted | ||
Sony | KV32XBR15 | NO VERTICAL SWEEP MICRO LOCKED UP, P-14/PIN 1&2 SOLDER SHORT | No vertical sweep or any control over functions. There was novertical drive, pin 31, IC-301. The DC voltages on data and clock lines,pins 47 and 48, IC-301, were present. Date and clock pulses were alsopresent. A resistance check between pins 47 and | ||
Sony | KV32XBR15 | RGB VERTICAL LINES IN PIX, ADJ. "REF" IN THE SERVICE MODE | Three to four retrace lines are visible at the top of thescreen. They do not look like ordinary retrace lines, but are of solidred, blue, or green colors. | ||
Sony | KV32XBR15 | H BOARD AND IC-51 HAVE BEEN CHANGED, REFER SUPPLEMENT # 4 | H Board and IC-51 has been change. -HQ COMMENTS: H Board has been changed to the H1 Board (1-629-621-23).There has also been a change in the sensor IC, it has been changed to P/N8-741-100-62 (CBX1618-51).
