Re: Star Wars with WG6100 problem with explosions

Is is the same with the other deflection board... same problem ???

I think its the Chassis Transistors on the way out.... Replace all 6 - Fresh White Heat Sink Grease too.... not too much though.

Fixed my sound today.... Bad 74ls161 doing the clock for the speech chip !!

Cheers, Colin

  I have tried two working Star Wars PCBs in my cab and both show a vertical bar on the right side of the screen whenever you are hit or when the Death Star explodes (either a white line or blue). I think this bar should be off screen and used to briefly flash the screen when this happens. Here are the pics:

  Also in the second pic you can see the right gun that has its vectors crushed.

  I have tried moving x-centre left a bit which improves the right gun a little but it doesn't fix the white line when you are hit. It isn't ideal doing this since the picture is off centre.

  All my voltages are spot on, chassis transistors give good readings, any ideas?

  Thanks

  Gavin
