I've been bringing an Asteroids Deluxe back to life... I've got the game working and now the monitor is showing images.
I'm seeing two things that need to be addressed:
1) Image is dimmer in the middle
The brightness in the middle of the screen changes while its powered on, ranging from slightly dimmer than the non-middle to very dark.
I've done a bit of research and it seems the HV diode might be the problem?
Also, I haven't done a cap kit on the monitor yet. Is this a symptom that might be solved by a cap kit?
2) Image is too large and the size seems to occasionally bounce between "too big" and "even bigger"
I suspect I should start by adjusting the X/Y linearity pots. That may change the "too big" image into the "right size" image. But I suspect it will not address the image size change.
Note that the letters/graphics are not "crinkly".
I'm worried this one points to some HV issues... which I didn't want to mess with.
Thanks in advance for any thoughts
