Sony | KV32XBR10 | HIGH PITCHED OSCILLATING SOUND, REPLACED R-527 | High pitched oscillating sound from the set and poor interlacei.e., looks like horizontal line pairing. Waveform at pin 1, A-84 connec-tor was 25Vpp, horizontal amp waveform at pin 11, T-500 FBT was 225Vpphorizontal. Inspection of R-527 revealed it was | ||
Sony | KV32XBR10 | SHUT DOWN, REPLACED R-608 ("F" BOARD) | Unit would go into shutdown immediately at power on. Foundthat Q-603 was turning on causing the unit to go into B+ Over VoltageProtection. The B+ was only a slight bit high. The emitter of Q-603measured approximately 1 volt higher than the base. | ||
Sony | KV32XBR10 | HORIZONTAL CENTERING, USES TAP SEE SERVICE BULLETIN # 102 | The Horizontal Centering Adjustment on page 30 of the ServiceManual omits the fact that a Horizontal Centering tap exists as shown onpage 36, the F board. If the remote commander adjustment is made withthe tap in the wrong place, some sets will exhibit | ||
Sony | KV32XBR10 | ANODE CONNECTOR MISSING, 1-540-006-32 | When replacing the A board, the Anode wire from the flyback ismissing. Is there a part number for it? -HQ COMMENTS: Please order part number 1-540-006-32 which is the AnodeCable. Future boards will come with the cable. | ||
