Quoted from jj44114:
Not sure I get why a tester is needed for these plasma displays. For a sound board or SDB I get it. Why not just plug into a working game and run the display test? I have done it this way for hundreds of displays. Never needed another tester.
I think you have already got the answers but in general, with any kind of tester like this one:
- you don't need to have an alive machine to test one or more displays;
- you can confortably sit in front of your test bench and do test + repair without standing up and down to go back to the machine;
- in case of nasty short or damages you avoid killing you working machine;
- when reparing a display you need to switch it on several times before having it good, this means connectiong it to the pinball machine as many times as;
- this tester runs a series of tests which are intended to confirm that all digits and segments are ok, in a normal machine you have to power on, wait, move to tests program, etc etc.;
- this tester goes straight to the point.
Now, before having it, I was doing exactly like you said, but I was tired of using my machines as test benches, keeping them constantly open and looking hugly.
Getting your feedbacks and positive comments makes me really proud because it looks like I produced something really useful not only for myself.
