ok I see that as taken as the starting point the agc pin of the turner that is good so we understand better as a routine it measures pins 3 (scl) and 4 (sda) should have approx 5v, the other voltages are correct
hello friend, if the volt condos They are very well look at the contacts that tuner has where you connect the signal cable that is closed and the signal cable is not making contact if they are open, close them. If this does not improve, you have to change the tuner to another one of the same number. regards
Good afternoon, brother, Thank you for your information, Yes, I'm going to check the Tuner's Internal Welds, Thank you for your information, Thankful.
Good evening RATONELECT63, you are greeted, I did the proper maintenance of internal welding and others that looked cold welds, more other touches and if, yes, it was the solution, it worked well, ... Thankful for your guidance, Thank you, Regards.
Good afternoon brother, I will check the points you just indicated, The Tuner will check the Voltages again to get out of doubt, AGC has 4.86V. - (MB) measures 4.92volts - Pin 7 measures 34 volts, I see them acceptable --- I will check the Line and adjust the AGC. Grateful, I informed you of the details of the repair, Grateful, Regards.
Good night Rigoberto Mtz. Thank you for your advice, I did intensive maintenance of the Turner, I corrected several Welds from the inside, also to the AGC circuit and even had cold welds in the Color Transistors, I solved all that area, I turned it on ... and everything came out Well, Failed Resolved ... Thank you Brother, very grateful, and the other thing was that I didn't know about the SF101 component. In itself, what is the function of that Component? I would like to know about him.
