Asteroids Deluxe resurrection
ChadTower:
Popped a new fuse in, got back to a spot. Fuse did not blow.
Pulled out two of the new chassis transistors and they test good as far as I can tell. Might be worth popping all four of the old ones back in and see if it goes back to how it was (a vertical line on X).
ChadTower:
Popped the 4 old ones back in to see if I could get back to where I started... nothing.
Pulled deflection board. F600 and F700 dead. Time to trace backwards from those and see what I find.
ChadTower:
* R620 and R670 are both short- big cement resistors, one on each X and Y.
* R613 and R713 are both short.
* R618 and R718 are both short.
* R615 and R715 are both short.
* R619 and R719 are both short.
Note: check values on these, they might be testing open because the intended value is below the continuity threshhold on the meter.
EDIT: nevermind. R620 and R720 test at 2 ohms which is the correct value. Meter's spec on continuity is <=50 +/- 30 ohms. I guess continuity isn't the best way to check low valued resistors.
SirPeale:
You don't want to use a continuity check to check resistors, always Ohms check.
Kevin Mullins:
You're gonna want to check ALL the small transistors as well.
