REQ: HELP! Crazy Virus B KB Problem?!
 

The Virus will randomly jump to the Effects Page?

Replaced ALL the Caps - no change.

replaced the 2575 regulator - no change?

Re-installed the OS to 0.9 - no change

Memory Battery is ok.

Was thinking of replacing the other two regulators (3.3V and 5V)??

It isnt the Tactile switch as i have buzzed that through....but i have measured different voltages across the button?

anyone have a clue or idea what it could be? any more test procedures? I have a small Oscilloscope and meter together with decent electronics knowledge but no service manual to follow?

Cheers guys! :)

Hello , do you've checked if power supply give a stable correct tension ? and for last since you've changed everything, replace the regulators too.
Try with solder iron to refresh the solder joint on DSP ic
