[Misc] MPC3504ex TouchScreen issue

[Popolopo]

If the touch screen have be calibrate wrongly and current when press at it, it will click on the other press(not on the finger). Is there a way to reset it?

I can't to go service mode, as cant press the check status. If able to, I not sure whether can press the sequence to go for calibration again.

Not shure if you can calibrate such a huge offset due to an error during the process - perhaps the touch panel is just faulty and the offset got more worse (since somebody intitally tried a calibration before). If this is a contract machine I'd probably get my hands on a panel from a donator machine or order the digitizer.

It was slightly offset before. But after wrongly calibrate, if I press "stop", it will go to menu button there.

If not mistaken, there are recovery mode like android. But I unable to go to that mode. Not sure the key combine is right or not. 1 and 3 hold then power on, after that 1 and 2 hold. Is that right?
