It sounds like a leaky capacitor on the power supply filter, which is located immedialtely off the ends of the wires coming from the power supply input. That cap's job is to 'soften' any voltage 'brownouts' that you may experience. It is the sudden 'drop' in voltage that causes most of the reset problems. There is a Zener diode in the same circuit that acts on the overvoltages. Bill G. Ilpo Partanen <ilppart@xxxxxxxxxxx> wrote: Hi! Been struggling with an irritating problem in my X5D. The problem is some kind of voltage peak(I assume) which resets all my sounddata (both prog & combi) to initsounds. This happens randomly at home or elsewhere when power is turned on (does not happen every time I turn the power on). I had my Korg inspected by the dealer, but no defect on the board was found..so I just went on using the defective board (should have taken the problem more seriously when it still was under warranty). My local Korg dealer could not tell what the problem is either. They suggested that I would replace the battery just in case. I don't think the problem is in the battery, but decided to replace it anyway. I tried to run both of the test-programs according to the instructions on Korgy Park's pages. However, the latter of the tests (the more comprehensive one with the voltage test) failed and my board hanged blinking the leds (combi, prog + etc). Can anyone help me with the problem. Despite this awkward problem I like the x5D very much and use it on gigs without any backup (risky considering the problem I have with it, huh!). I would appreciate it, if anyone could give some information to fix the problem. -I- _________________________________________________________________ Tired of spam?
