No problems, always glad to be of help.

BTW Marco, I skimmed over the Montreal Kijiji, and wow it's the Klondike of old television! I only checked the pages from december and there is at least 4 sets that I would grab.

things may be the same OR very different.
The pin control is VR541 The cap that goes is C541 10mfd. Its
off one end of the control. Its all tward the rear of the right
hand board ( looking from behind) . The board is on
hinges so you can fold it back.

The 2 manuals are similar. so I can take your KV-1204A.. if you have it in PDF ( scan. ) Thanks Zeno...

Sony KV-9200
 
Recently I obtained this little tv that Dreamsbeard had for my Zenith solid state.. so ,You told him to transfer the yellow wire to resolder on F1 or F2 or F3 .. But .. there is a white wire welding with the yellow wire. So to have a better focus, should I leave the white wire F1 terminal and move the yellow wire on the last two terminals? either F2 or F3 or the last point .. or should I move the yellow wire with the white wire on one of these terminals?. Thanks for the help :)

here is the picture.

My manual shows a different socket PCB. On mine the
wire goes to one of....
F0 ground
F1 275 V
F2 500V
F3 870V

The other end of the wire to move goes to a 560 K ohm resistor.
I think the white wire is just a jumper & not to be moved.
Usually moving focus jumpers make little or no difference in
the picture.
BTW the set in my manual looks very different ( newer ) than
yours.

Okay, is that there is still the danger of blowing up the CRT by changing the yellow wire terminal and it is safe given the different voltages?

Which terminal do you advise me?

Hello zeno..Can you please showing me a picture of your socket PSB ? i'm interested to know how is yours ( in the picture you have from the booklet ( sheet ). Thank you in advance..

Marco-nix 04-19-2015 10:06 AM

okay, no answer, in that case i will try by myself....

zeno 04-19-2015 10:19 AM

Sorry I have no way of sending pictures.
I see different style parts & some different
designations. Probably very close BUT......

You can use a web-cam for taking a photo.. but you gave me some different voltages starting:

F0 ground
F1 275 V
F2 500V
F3 870V

The 2 wires ( white and yellow ) are in the same tip.. so you tell me that the white one needs to be stay there because its a ground,, the yellow one is also on the same tip but..... if I follow what you said to me. i can move the yellow to one of those ( these ) voltage tips.. and are not the same volatge. That's why i asked if there is no danger if i try to move the yellow wire on : 275 v or 500v or 870 v !..

zeno 04-19-2015 03:08 PM

OK is the white wire the one going from F0 to the
green spark gap in your pix ??
If so it stays where it is. Its just a jumper.

If not that wire where does the white wire go ?

Unless you move the wrong wire there is no risk.

The white wire is in place to terminal F0 ... What I want to know if I weld the yellow wire to the terminal F1 or F2 or F3, What kind of image I will have and what is the danger being given the different voltages.

Be sure you are moving the right wire.
On my manual the wire to move goes to R711 560 K ohm.
The other end of R711 goes to CRT pin 6 & SG705
No danger if you move the right wire.
The pix may change focus better or worse. Often there is
little or no change moving the jumper.
