The candy files...

Ummon:
Okay, so the amp and speakers are working, but I'm getting a 60hz hum through them. Anybody have an idea where I might start?

Ummon:
Welp, I took back that Sears auto-power-turn-on unit. They didn't really have a means to test it, so they exchanged it. They didn't even require a receipt...which I have but wasn't able to find before I left....it's actually been almost two years, so hey. Anyways, this unit doesn't work with my computer, either. Oh well. Two buttons to turn on. Not a big deal.

Also, still not sure what the deal is with the JPAC not working through PS/2 on initial boot, but using the same extension cable and a PS/2 to USB adapter cable, it does. So I'm guessing the cable is good, and that works so fine.

Ummon:
I finally got off ---my bottom--- and got a new-model JPAC. I wanted to see two things:

- would the video amp make it nice and pretty?...or over-saturated?  I didn't think this monitor needed an amp, as the picture brightness was the same with a game board....

- would the controls issue be resolved?  Now, I already resolved this with using a PS/2 to USB adapter, but since I was getting the thing anyway, it'd be a small bonus.


The answers, in reverse order were:

- Yes - controls issues resolved, at least the first and only time I've turned it on. Note: the keycode set on the new version JPAC is slightly different...I think I now remember Andy saying this.

- and yes, the picture is BRIGHT. Not over-saturated...but so bright it's either showing the convergence to be slightly off - or there's phosphor bleed or something, cos with some graphics it's so bright I can't see the natural scanlines, and you might notice that cninja screen isn't the most defined...not as defined as it seemed to be with the old model JPAC.

I did turn the brightness on the monitor down a little, and messed with the color drives; the former was helped, but the latter just messed it up. Would the video amp compensate for old caps?....is it over-driving the monitor?

AndyWarne:
If the monitor is designed to work with the standard game board signal levels, then the J-PAC amp will drive it slightly under this level. Its not capable of over-driving since the supply to the J-PAC is 5 volts so the signal cant go above this level.
The old and new J-PAC have exactly the same video amp IC.

Okay, thanks. Also, my old JPAC is so old it doesn't have an amp; you told me that in another thread a few months ago.
