sur arcade control, on m'a repondu ca :
Normally these flybacks crack just above the pots , You will need to move the metal surround away from the front of the flyback to see this properly.
If you see a crack it will need to be replaced , Part number is MSH1FPU07 .
If you don't see any cracks the problem is more than likely the CRT socket on the neckboard , these corrode internally and only noticeable if you look where the focus wire connects to the focus pin , it will look slightly green in color.
As for the H-Size there is a single pin jumper that can be moved to adjust the size in steps , it's located beside the flyback in the power supply section. ( The wire is Red ) it can be on N =Narrow , M-Medium or , W=Wide.
en gros faut voir si la tht n'est pas fendu, ou si les pins de la carte au cul du tube ne sont pas rouillés
ca je n'ai pas compris : and only noticeable if you look where the focus wire connects to the focus pin , it will look slightly green in color.
et pour le h-size, il doit y avoir un cavalier, pas loin de la THT dans la zone d'alim
au je bien compris ???
