GE Wireless Keyboard - intermittent keys

It's a brand new keyboard - basically just got it out of its box. And haven't used it much in the last few days. It's been in storage the past 2 years. I also thought it could be mechanical... but then there'd be times when the keys would respond... it's really the h that's most crazy - even when it's working, it would fail to type maybe 1 out of every 8 times you press it. But now... even when I'm using a backup (wired keyboard) - so it's no longer getting used, when i test it, it seems to have gone dead on those set of keys.... Sigh. I should have tested when it was still under warranty. I guess there's no help for it but to open it up and see what I can find...

thanks guys for your inputs. i've opened the thing - there were a ton of screws (am exagerating, of course...) at the backside of the keyboard...

the thing doesn't even use a circuit board base. it uses a film base - 3 layers of film where the 2 outer films shift resistance when pressed.

the only circuit board in the thing was on the upper right side - a small maybe 1.25"x3" kind of deal where all the connections go to.

And guess what - the keys i mentioned - h, j, u, 6, 7, m and backspace (yup - backspace!!!) are all connected at one trace. I thought it was going to be a trace problem - but it was now becomming intermittent when i was tinkering around.... bottomline - the trace seemed fine visually and signature wise.

I have two hypotheses - it's either cold solder issue on the main board (which seems unlikely; i'm currently using the keyboard in question - and i didn't even try re-soldering...) or one of the 3 screws which connect the ckt board to the plastic case is too tight (as in way too tight) - this is the screw that's near where the film connectors start entering into the ckt board area.

so it IS a quality problem on GE/Jasco's side.... Btw, I did send an email to Jasco on this (original problem)... no response (it's either they're slow or they don't plan to answer).... I wonder if they're even aware they could be causing problems like these...and am even wondernig if I should email to them my findings... what do you think?
