Question about Music
I went to turn on The Technics PR-305 Digital Piano on I got a humming noise, I turned up the volume all the way up but got no sound even through the head phones. I learned that the speaker blew. and I don`t have any speaker surround on it, that may have caused it along with the amplifier, Can the amplifier be repaired so it can work again?
Yes it can.....but you will need the schematics and some test gear in order to do it.....and a soldering iron....what do you mean by no surround on the speaker?? Can you post a pic??

I would also be inclined to check all the larger electrolytic capacitors in the power circuits as well for AC bleed.

yes maybe you may fined that some of the power to the led is being blocked by causing a larger resistant to the led which will cause it not to light up as bright.

Yes. It is a fluorescent tube. It has to be from the OEM though.. It usually comes as a diver board and tube assy.
