Hanrarex polo 16:9 to normal 28 inch 4:3 possible? (SOLVED)

Hi
Thanks for all the info :cheers:
I have looked at the neck card, it has a funny crt connector.
Is it "just" possible to swap out the connector with a normal one, I think I have one from an old tv, that I can use

It should be possible. Not sure why it has a double focus socket as the flyback doesn't have two focus wires.

Hi
I have now found a new neck connector and solder it on the pcb :)
I have also checked that the PSU is outputting all the volts 145V,12V,25V,15V and 25V :applaud:
A quick check of diodes, and big resistors - all checks out OK including the HOT...
Now I am waiting for some new 2.2K resistors (R219) then I will change the components that not match a normal 25-28 Hantarex polo.
I might also change the flyvback to a "normal" HR7191

HI
I have now put in a new 2.2K resistor (r219)
Also a new HR7191 flyback
When i power the chassis on, then I get this
(I have before used this CRT to test/repair Hantarex polo monitors on, so I know that my CRT is working.)

Problems with the CRT socket. I'll make a post later. Don't try again.
