Hi;
I have a Gravitar that worked until I fixed it!
The display is garbled and instead of the usual coming up slowly when powered up, the display is dark then the display "pops" up, already bright etc......
Anyway, it has a Clay AVG replacement board and D102 is bright when the game is fired up but D101 is dim.
I poked around the PCB on the bench and found C110 broken, so I replaced it and IC A/B11-7 was bent underneath the IC so I straightened that out as well. Funny how the game worked even with those 2 components not quite right.......
I think that maybe the AVG PCB is bad, as indicated by the dim LED but before I replace that with a good one and possibly damage that one, I would like to get some opinions on why the one LED is dim.
Thanks much
Jeff
