Hi,
Thanks for your help!
The monitor was working, but the image was squished down on the bottom of the screen. I search for advices on many places, but I quickly found help here on Arcadecontrols.
Special thanks to Ken Layton who conviced me to go for a cap kit and telling me where to get it cheap (from Zanen Elect.).
I contact Zanen and they send me a complete cap kit and a vertical deflection chip (a small 21$, shipping incl. to Canada). They advice me to try the caps first and then change the vertical IC if it did not work. But since I had the chassis removed, I decided to do everything in one step. The bad side, I can't know what was the real trouble. The good side, it's now working better than ever!
Thanks again,
Yanick

You should keep your old chip. The reason they told you to try it with just the caps is because if it worked, then you'd know you had a good chip to save for a future problem. Now you have a maybe chip that might or might not work.
Don't know how everyone else feels about this, but whenever I change a chip, I like to put in a chip socket so I can swap chips quickly. Helps when I'm trying to diagnose a chassis (or board) and know I can pull a working one from another chassis to see if that's the problem. I try to use high-quality sockets to ensure good connectivity.

If the chip was very expensive or difficult to find, I would have tried just the cap kit first. But at 8$, well, I think the time I would have lost reputting everything together in my cabinet worth more than that. And dischargind my monitor with the screwdriver and my rubber gloves... humf the less is the best :)
I taught of putting a socket, but since the heatsink is fixed on the chassis, I was worried about the alignment of the chip. Anyway, what are the odds I will ever have to change the chip again? My cab is on less than 15 hours/week.
Take care,
Yanick
