My Battlezone decided to not work yesterday. I now get a solid red (not blinking) LED start button. Nothing on screen...
I drop her in to test mode and I get the cross hatch, and it read REV 01D in the middle(ish) of the screen. I am not 100% sure if that is normal or not... but it does demonstrate the monitor works fine.
As soon as I drop out of test mode I get the solid LED and nothing on screen.
I've of course done the normal "laymen" fixes... removed and re-inserted both edge connectors... checked voltages (5.14 on the mainboard and 4.78 or something on 2nd board (which has always measured lower))... tapped on various socketed chips.
I DO have the BZ high score kit so that should eliminate many of the socketed chips I do believe.
Suggestions?
REV 01D
