It's been one of those weeks where for every one positive repair accomplishment I achieve, two or three new problems surface in its place.
Today I've been working on Berzerk. I actually fixed the speech problem (there was no speech when I bought it) and then decided to tackle the battery install. The original battery was already gone from my board when I bought it and I decided to put in a rechargeable cordless phone battery and mount it far away from the boards as shown in several online tutorials.
I'd picked up some red and black wires crimp to the new battery so it could be mounted further away. The wire was a little bit bigger gauge than the ones coming out of the new battery, but the home depot guy assured me that was fine. I desoldered the battery holes area on the board, stuck the stripped wires through, soldered them in, etc.
I turned on the game and everything seemed normal, but the credits were still FF. I hit the bookkeeping button on the board and it brought up the Credits in the lower left and I hit the fire button to clear the credits to zero. I wasn't sure what to do at this point and couldn't seem to get out of this menu, so I hit the reset button on the board hoping it would now boot up in proper credits/high score save mode.
Instead I got one beep, light turns off, and all of a sudden there is garbage on the screen. I turn it off and then back on in horror and again it stops at one flash, one beep, and a garbage screen. Could I have damaged the roms doing something along the way? I've never had a problem with this berzerk before.
