Leslie:

Jut saw that my post has been degraded from 5 to 3,5 stars. So it looks that everybody can rate a post even without giving any comments on this post? That's pretty annoying...

Well, why not? Of course you can say whether you like a thread or not without posting anything on it. But my suggestion is to just forget about the flippin' stars. You can't even search or sort based on them. Even more useless than the tagging system...

@Jesper: just about the only way a piezo element can fail is that one of the wires snaps off of it. It is basically a slab of stone with two wires attached to it! Therefore a new element might not cure your problem, but it is of course worth trying.

Yeah, you're right about the flippin stars rating. The value of posted compliments or criticism has more value for me then anonymous rating. Enough said! 

@tournedos, I have very limited knowledge in electronics (high school only and thats a while ago :P ) but I read somewhere that the piezo was rahter sensitvie to heat.

Last summer I had my BL7000 in charger since it was missbehaving outside charger (turning on and off all the time til battery was drained). Something happend a hot day and my original batterypack got very heated, it was almost too hot to hold your hand against faceplate. When I pulled out the batterypack it was also very hot. After I let the BL7000 cool down and replaced the batterypack with a new one the faceplate is totaly dead, with no reaction on other touch or a more brute tap :(. Suspected that i had freid the piezo then.

@Leslie, I will take up that offer, but lets first see how your "blue-cap-adventure" goes :). Btw in swedish your saying is "En bild säger mer än tusen ord" we use it also. 

Cheers

Well I guess the metal layers that make the contact to the crystal material could somehow be damaged by heat so that the piezo won't work anymore... certainly worth trying. You don't have to attach the new piezo element to the faceplate to try it, it should work simply by soldering it in place of the old one and tapping it.

But please be carefull if you wanna test this way not to make any short circuits.
