Bloxifier Posted May 7 Posted May 7 I found a Casio CDP-120 for free a couple of days ago, and whenever I try and turn on the piano, the power light turns on for a tiny bit (half a second or so) and then fades away, during this time the voltage coming from the PSU drops to about 6 volts. It is not the power supply that is causing the issues, as I've tried both PSU's that I have. I have also recapped all of the electrolytics, still nothing. I feel like there is a short circuit in the PSA1 Board, but I am not completely sure. Should I replace the LA5756 voltage regulator? I've seen that it may be the issue. Any help would be appreciated.
