you can try pushing the soft reset button a few times after the hard reset.
it worked for me once with an older unit I had previously.

btw, how did you hard reset? you need to take the button cell and main battery out and let it stand for 10-15min to make sure all memory is flushed.

I also know that if you don't use an lcd screen for some time, it degrades..not sure why..my casio lcd tv screen deteriorates even when I don't use it...

else, how about going back to HP? since its no longer in production, they do a one-to-one exchange with their ex-stock units. that's how I was able to change 4 new sets in 3 years! I bought my J568 around 3 years ago but the current set is only about 5 mths old...heh heh
each time a dust speck appeared, I bring it back for exchange due to my extended warranty but i heard they recently stopped extending the warranty which means their left over stocks are low...
