The tdq-6f2-m has one and remains the same but has many pins and is not the same. Can it be or am I wrong?

they are all replacements with each other, in some chassis all the pins are used in others no. it is not always the tuner that makes the fault sometimes they are external components.

Did you notice the voltages ??? it is likely that a voltage is not coming look agc 4v to 8v sda 4v to 5v scl 4v to 5v Vcc 5v vcc 33v Look suddenly you are not getting one of these voltages

Thank you very much for your contributions ...
Can someone pass me the diagram of this tv ..
Because the only voltages that arrive are 5v .. and 31.9 v arrive or so and the rest I have none

You do not need the diagram to solve that fault .... the sda scl pulses are not coming just back the track there must be a cross diode or the chroma must be broken because those pulses come out of there ... just back the tracks from the varica and tell us how you are doing ....
