I have a Zire 21. Recently, upon power on, the entire display goes completely black and is thus unreadable. The unit appears fine apart from the display, for instance, Hotsyncing successfully uploaded data entered into the PDA prior to this problem's manifestation.
This symptom did not occur after any discernable mishandling, (such as exposure to liquids that might have generated a short, or a shock.)
I have tried the reset button to no avail (though it does reset, as evidenced by the powering off of the display when the button is pressed and held).
I am about to pop the puppy open to see if I can find an obvious short, or perhaps the display cable has somehow slipped in its connector, though I fear a display logic failure.
Questions:
Have you ever run across this problem before, and if so how was it solved?
I am emotionally prepared to commit to buying a replacement, but if a relatively simple part swap (say, 1-2 hours work by an experienced, but non-professional, electronics tinkerer) with an otherwise fried Zire 21 is feasible, I would rather do that.
As I have said before on this forum, my work environment precludes the use of anything more sophisticated than a Zire 21 (nothing with memory stick capability, for instance) so suggestions of "replace with XYZ better model while you are on the market" are not useful.
Thanks.
David
