I have a Promethean P5110 (the P500h head) that is starting to show the "slow startup" problem that they get before the power supply goes out. I contacted Ibanez, and the repair department basically told me they have no more power supply parts, and it's not repairable. Has anyone successfully had one of these power supplies repaired outside of Ibanez official support? (ie without just replacing the power supply board) I have a good repair tech here, but "switching power supply startup problems" are pretty tricky. I'm not sure how I can live without it. What will I do? I may cry.
