Pa1xpro calibration

avellani · Post by **avellani** » Tue Aug 12, 2008 1:16 am

I just finished replacing the tap tempo button (2nd time in 3 years). Otherwise, the keyboard has been wonderful. I put the keyboard back together and everything woks except the display. I seem to remember this happening the first time I replaced the button, however I cannot remember the procedure. I think I have to hold down a button or two and then power up in order to recalibrate the screen. Help anyone?

Thanks!

Hi John

This is the procedure to re-calibrate the touch screen when the screen is out of sync....

1. Power on and wait for PA1XPro to start up.
2. Press "Global" mode button (enters Global Mode)
3. Press and HOLD DOWN "Global" button (again) for a few seconds until the calibration screen appears

Cheers

Pete

Peter; Thanks for your help. The screen is still blank, so I'll have to try to get it to a repair center. I did notice this past winter the screen took an inordinate amount of time to brighten when it was cold, so mabye the screen itself is shot. The only other thing I'm going to try is to preseat those black gromets that fell out when I removed the circuit board. I had left them off since they were wreaking havoc when I was trying to reseat the circuit board. Maybe that has caused a problem. No matter, I appreciate your help. Thanks again, John Avellani

Hi,

did you check the contrast - maybe it´s up to fully bright.

Hello John,

Was the screen working before you took the keyboard apart?

This might be a shot in the dark but the PA1X casing is metal and without the rubber grommets the circuit board might be shorting somewhere.

Thanks Detlef; yes I checked the contrast, it was fine. Dave, the screen was working before so to test your theory, I lifted the circuit board away from the keyboard and I turned the keyboard on, but no luck. I'm just going to try to find an authorized repair person.

Thank you both for your help.
