Philips N4510
Dear Sir, I´m from Portugal and my father gave me a Philips n4510 wich has lots of memory to me.
But... As soon as I turn it on, it stars FFW, RRW and Start at same time. I tryed to substitute the transistors on the Flip Flop PCV, but it is in the same mode. Could you be so kind to give me tip about this matter? |

Re: Philips N4510
Hello Paulo,
I do not know the N4510 or similar and not familiar with these Flip Flop PCBs, so forgive me if I ask a silly question. How do you know that FFW, RRW & Start are active at the same time, is it because the respective indicators on the tape transport touch buttons light up ? Do you have any control of the tape transport ? David |

Re: Philips N4510
Dear Sir, I just know that the buttons are light up and the three motors plus the solenois are active. I´ve tryed the substitution of the transistors but it keeps the same

Re: Philips N4510
Well, here I am begging for some help again. I can´t solve my N4510 problem.
It keeps in the same satatus. The three motors keep on working at the same time and the solenoid is activated as soon as I turn on, and I do not have any control of the tape transport. Please, could you be so kind to help me |

Re: Philips N4510
Have you checked the supply voltages, in particular the +2V (or so) at pin 13 of the flip-flop modules?
