Hi there!

I've got some trouble with both of my SimPADs. They seem to have both worn out capacitors which are used by the touch screen if I'm informed correctly!?

The only thing is: Where are the capacitors? On the mainboard, there are 2 *big* capacitors on the lower right site. Are they number 15 on picture http://opensimpad.org/images/2/27/SIMpad_1600x1200.jpg ???

Well, maybe I'm totally wrong, so I will describe the actual problem: I've got WinCE installed on the first, some kind of Linux on the other SimPAD. On both I get the following symptoms: If I recalibrate using the built in software on the WinCE one, everything is "almost" fine. After a few seconds/moments, the touchscreen gets some kind of uncalibrated. Only the center part of the screen works fine (maybe 50x50 pixels or something like that), but all other parts of the screen have some offset which gets bigger by the distance from the center...

Did anyone else have got such a problem? Can I get the SimPADs back to normal life if I replace the capacitors?

clean the connector? which conector du u mean? just the point, were the cable goes on the Mainboard?
And: it doesn┤t realy matters which (of those 2) capaciators is broken, just take another one, and it works or doesn┤t. Or Not? Is the board of the Pad a "multilayer" board? (I don┤t know the correkt english word but i hope you know what i mean)
