I am pleased to have been accepted in this website, so thank you very much!
I am 73 years old, and an ex-musician...only because I am too old
I have a wonderful Roland E600 synthesiser, which I have owned for quite a while. It is all I have now, and can't afford a new one, so I am hoping somebody can give me a clue or two what is wrong with it.
It worked fine every time I turned it on, but last week, when I pressed the power button, the touch sensitive display panel just stays flashing on and off, very rapidly.
I tried to find a method to reboot the computer side, but without luck. And so, having repaired many electrical devices down the years, I opened her up. Firstly, looked at the power transformer board, which accepts 220 volts ac, and reduces the volts according to whichever section it is supplying. I checked very carefully for swollen caps etc, but couldn't see anything out of the ordinary...although that probably doesn't mean much!
I then progressed to the power board...same result...no distorted caps. Main amplifier board also looks ok. I had turned the power off a few minutes prior, for safety sake, but noticed that on another board, which has no specific name, there are several large chips, and 2 of them were still very warm to the touch. So now I am wondering if they, or a controlling component, has/have failed. Now, I know these chips are like hens teeth nowadays, because the keyboard is old....but I would really love to get it working again, if possible. Being in Spain, it would be too expensive to ship the whole kwyboard to anybody who might be able to repair it, so...I will try myself, and if it isn't possible, afraid I will have to chuck it away...with the other sitting under my bed: Solton MS60, which requires at LEAST a new chip, costing 185 pounds...if I can even locate one.
I can provide photos of pcb's and components, if that might help, and also a short video of the display screen misbehaving!
Looking forward to any kind of advice, even if it is 'chuck it away'! It is otherwise in pristine condition... I love my instruments,
Thank you so much for any and all advice and comments.
Respectfully
Nicholas Cann.
