Looking for a repair manual for a Roland VK7 keyboard. I googled and the only results are for Owner's Manuals. I believe I am having a power supply issue, as I inadvertently left the VK7 turned on for several days and now it won't power back up. I may have fried a transformer, as there was a burning smell when I got back into my room. All of the capacitors that I can observe look OK - no bulging/etc. Any help appreciated.
 
sounds like you have it opened up already,

power it up, feel the boards for hot chips.

had a PCM54 DAC blow on a DX7s the other day, actually started smokin,
replaced the hard to find chip, lights up but probably needs a internal reset as display does not always show the right characters,

if you replace the chip, use a socket. some of those chips do not like to be soldered.

OT: cool Roland history articles>
