Hello friend, I'm from Brazil. I have a Roland HPD10 could you be helping me? my country's authorized dealer condemned the motherboard, and I'm not in a financial position to buy another one at the moment, because here it's very expensive. I wanted to try to fix it. some time ago it started to lock some buttons, as the days went by when I turned on the screen it just lit up but did not open any function, nor did the buttons and pads respond. now when we turn it on, it just keeps the display on without responding to any command. if you can help me find out which component on the board is defective.this equipment has a lot of sentimental value for me, I didn't want to lose this instrument. can you give me your contact please?
