CAUSE ACTION Various components. If Q702 immediately goes short circuit when the set is turned on, check that D716 has not gone short circuit or that T700 (chopper transformer) is not short circuit across pins 7 and 2. Note that D716 is connected across Q702 emitter earth return resistor, as this is only 0.22, D716 needs to be removed before testing. If the power supply works, but fails after being run on soak test, replace D708 and D709, also check that the main smoothing block (C705) has not got loose rivets. In some cases it is possible for the HT to rise significantly during standby, the normal value of the HT in standby is anywhere between 120VDC and 130VDC ( this rise is due to the line output load being removed). If this increases above 130VDC, there is a problem. Check the feedback circuit around the opto coupler and D751. Note that it is important that Q702 is replaced with the correct type or long term reliability problems will ensue (MJF18006). The HT voltage should be set to 113VDC on a blue screen (pull out the aerial and wait a few minutes - the screen will turn blue due to lack of line sync).

The above faults are normally caused by R751 and R777 going high in resistance. Both of these resistors are 0.33 and go high by a few hundred milliohms, as most multimeters are unable to resolve resistances less than 1 it is advised to check by subsitution. In some cases, intermittent start up has been traced to D700 (HT rectifier), D751 (prefive volt rectifier) or C756 (smoothing capacitor). Once agian it is best to replace these components if in doubt. R612 is the supply feed resistor to the vertical stage. All sets should be modified so that a 1.2, 0.5W resistor is fitted in series with R612. To do this, replace wire link J13 with the resistor. Note that the HT supply should be 113VDC on a blue screen (pull the aerial out and wait a few minutes - the blue screen will appear due to lack of line sync).
