speedball help

[moviedave]

When doing the voltage checks on my speedball, the LCD on A8 appears to have shorted out.  Everything was normal up to that point.  Finishing the voltage checks, B1 and B3 were both around 160v.  B1 should be 75v and B3 should be 100v.  Would that have caused the LCD to short or would the LCD shorting have caused the much higher voltage readings.  Or do I just have two separate problems?  Thanks for any help.

Yeah the LED not conducting means the tube is not conducting and that means the voltage feeding the plate does not get pulled down to the operating voltage. Try touching up the solder joints at each end of the LED. Of that doesn't fix it we can send another.

We have a new email for replacements parts, [email protected]. I thought up that address myself, no kiddin'. Shoot us an email and we will get a replacement LED in the mail to you Monday.

Sounds great.  Just one more question.  How do I get at the LCD at A8 with the Speedball soldered in?

You can remove the screws on the smaller PC boards, then slide them out of the way to access the LED.
