Schneider euro 70222 service mode

[Marko]

Hi there,

The flyback transformer blew in my TV set. I replaced it and picture
came back but the picture is a not centered and sides are sligtly
pulled in and rounded (e/w control?). Is there something else defected
or is it only wrong settings? I tried to find trimmers inside to set
the picture but couldn't find. So there might be a service mode to
enter but I don't know which buttons to press, so if you know it I'll
be more then happy to hear it.

Thanks,
Marko
