| Sony | KV32TS46 AA-1 | dead | Unit was dead. has shorted horizontal output and shorted Q601, & Q602 components in power supply replaced. After replacement unit will turn on but still has no secondary voltage output of power transformer. All relays click but no high voltage. Has sound. | Tech needs to check the condition or RY602. RY602 is the switching relay that turn on and off the set. The relay is ""HOT"" switched. In other words one side of the relay is connected to power oscillator output that runs nearly 350 vac Peak to Peak at 90Khz. Once the relay is closed this energy is placed across the power output transformer and provides the drive necessary to produce the B+.Measuring the input voltage of the relay to ""HOT' ground found it to be 150 volts DC mode. But on the other side of relay we has 3 volts DC mode. Unit has defective RY602 relay. "" | Muller |
