Re: Best place to start with Amplifone 19"

Start with the basics; check all your fuses / fuse holders. Even without a
high voltage prob you would get that familiar crackle of high voltage if you
had it. If all fuses are good and still nothing check all your connectors;
these are common points for cold soldier joints. If the monitor had power
and no signal from the game board you should see the spot killer led lit on
the deflection. Assuming deflection is good. I would recommend looking at
the over voltage pot. R17 on HV. Do you have neck glow? How about your B+
voltage?

If the caps are not looking to swift; might not be a bad idea to shotgun all
boards. As we all know some techs take shortcuts. I have a star wars up
right and other than just doing preventative maintance my amplifone has been
solid. I have had WG6100s do this to me though.

I would strongly encourage you get a high voltage prob; I use mine more than
I thought I would and it beats guessing. ;-)

Good luck!!
