I recently purchased an iPAQ 3715, but suspect I've got a faulty unit - the screen is prone to flicker & then die (either to a white or grey screen).
However, it *seems* to be related to the wi-fi settings. If wi-fi is disabled, the device appears to be quite stable. The same seems to be true if wi-fi is enabled & a strong connection is available.
However, if wi-fi is enabled but no connection available the screen will immediately die, although the touch screen remains responsive. I've discovered that I can enable wi-fi, see the screen die, but then tap the screen where the wifi button is located & it comes back to life!
Does anyone have a resolution for this, or confirm my suspicions that it needs to be returned as faulty?

To perform a soft-reset (if the device has locked), briefly insert the stylus or a paperclip into the reset hole on the bottom left of the 3715
To perform a hard reset (losing all data!), insert the stylus or a paperclip into the reset hole on the bottom left of the 3715 while holding down the far left and far right of the four main buttons. Information in the iPAQ File Store will not be lost, but data on the Internal memory will be wiped. If I could be of further assistance, let me know. If this helps or solves the issue, please rate it. Thanks, Joe
I am not an expert on this. But I just had a problem similar to this as the unit kept reporting a FAIL on the screen calibration test. So this is what I did and after I did this, the screen calibration passed.
I went back to the screen alignment tool and performed a screen alignment with the stylus and this solved my issue. I then checked the self test aand it passed. This may not workfor you, but you can try it. Also you might want to check to see if you have any third party programs that are affecting this. The only way, you'll know is to remove those third party programs, one by one and repeat the self test to see if this corrects the problem. Good Luck
The dreaded "allign screen problem" strikes again. This is a known bug of these rx ipaqs. You should simply try to see if the ipaq passes this stage if you try to allign the screen a few times. If not, try a firmware update/rom update (from the hp site) If this woun't work then the problem is located on the motherboard,where a small chip called the touchscreen I/O controller has failed. This isn't fixable by replacing the screen, only the whole motherboard. Unfortunately most of the first generation rx 3715 units (first revisions) carried this problem just waiting to happen.
Please ask more details if you need to better understand any of these methods above.
