ok I left only the bridge from pin 11 of the P card to PIN 1 of the pb card, I connected the P card to the A (main) card and when I do so I have voltage 5. 16 and 24v for a few seconds then the television goes back into protection, removing card A and bridging the SUB P ON I HAVE NOTHING, ok I'll do a check as you said, I'll update you

[Davi.p]

i told you check control pins.. is it so complex?

[riparo]

Davi.p forgive me, I'm a hobbyist, I just reminded you of what I did previously, ok ok I'll check and sorry, have a little patience, thanks again for your patience

[riparo]

hi, Davi.p as you indicated, I checked all the control pins of the connector of the P board and the voltages when turned on rise and then fall again, I tried to make a bridge between the pwn on pin and the 5 volts and on the P board as well as having 5 volts fixed on the 16 volt test point by measuring I have 5 volts fixed, the 16v are not activated

[Davi.p]

You don't follow me! i need the voltage of every control pin when 16v is up, that are: 13, 17, 19..

Forse non ci capiamo, allego la foto di tutte le tensioni rilevate sui pin del connettore della P card. Spero di aver fatto bene

[Davi.p]

It is mandatory to write Enlgish here....
i report the pins for reference: 11=5Vsb=???, 13=SUB-ON=5v, 15=KEY=2,3v, 17=Power-On=2,6v, 19=AC-OFF-DET=3,6v

the pin 11 is not GND i guess, not for the ,manual...

[riparo]

yes I understand, pin 11 is 5v, I wrote it wrong, all the references you wrote are correct

[Davi.p]

ok, so the correct way of turning on the voltages is to keep up pins 13,17 and tieing them to pin 11.. try the P board alone, if ok then repeat the guide with this modification.. good luck..

grazie per l'aiuto che mi stai fornendo Davi.p ti faro' sapare

i apologize

hi Davi.p I made the connections you indicated, connecting pins 13 and 17 together, then I connected them to pin 11 but the 16 volts on the P board are not activated, furthermore by making this connection I no longer have the 5v standby, by disconnecting the two pins 13 and 17 the 5 volts return, this is very strange, it seems impossible to me that the 16v cannot be activated

[Davi.p]

I guess that SUB-ON is not a control pin to turn on the 16v but is the 5vsb rail (5V is too high for a control pin..) !!! (Aaah.. Panasonic, confusion!).... so i guess also pin 11 is right GND (why you told so first and after not??), if you check the P board connector at open circuit and you see SUB-ON=5v and Power-On=0v then we are at horse... so connect only SUB-ON---Power-On and check for the 16v output.. if ok then redo the previous guide test..

[riparo]

nothing in fact, this power supply is a hard bone, I connected the sub on and the Power on but nothing happens, I still have no 16v, I always wait for your provisions, I do not give up

[Davi.p]

post the voltages of pins 11,13,15,17,19 at P board connector disconnected..

[riparo]

hi Davi.p I managed to turn on the P board and get the fixed 16 volts, I bridged pins 15 and 17 with a 1kohm resistor respectively key and power on, now I can follow the guide posted by you right?

[Davi.p]

I don't understand what you did, Key is not a control pin, it's the button line of the key board , i guess,.it only passes through on the P board, it doesn't have a role for it..

[riparo]

i would not like to be wrong, but the PINs used to access the card are 15 and 17 cmq as soon as I have 2 minutes I update you I would not want to be confusing on PIN 15 which is instead the 13

[riparo]

i confirm Davi.p the PINs used to turn on the card are 13 sub on and 17 Power on, waiting for you if I can continue with the guide signed by you
