Re: GNR TS700 2 seconds to black
The one that doesnt work goes out of range.
I have attached a couple of pics of the working one measure for capacitance and resistance. I would imagine swapping them both at the same time would make sense. |

Re: GNR TS700 2 seconds to black
That will be good way to go. I always test those tuning caps, a must, when I work on the inverter section. Resistance reading should be infinite since cap is an open circuit device. If the meter which runs on 9V batteries can show the resistance reading, just imagine what happen when the cap is exposed to a couple hundred volts of pulses.

Re: GNR TS700 2 seconds to black
Ordered some new tuning caps and transistors for this one. Looks like i'm going to spend more more money on this than its worth but im keen to get it up and running. Bit should be here tomorrow so I will keep you posted.

Re: GNR TS700 2 seconds to black
Tuning caps arrived today and new Transistors.
All cleaned up and then fitted. Just tried it for an hour and its working fine. Cheers for the tip Budm... |

Re: GNR TS700 2 seconds to black
No Probs,
Another lesson learnt there! It's not all good news though unfortunately as I have now ran out of things to fix! Well apart from the Barco. |

Re: GNR TS700 2 seconds to black
But once its fixed it will be even more satisfying!
Only got to get the 18v line up and running then it will become easier. I am off next week so I will have lots of time to look at it. |

Re: GNR TS700 2 seconds to black
I have repaired many Dell and ACER with these bad tuning caps used in the Royer oscillator setup in the inverter output circuits, most of the new monitors do not use the Royer Osc any more.
