Definitely not vintage... but could use some help

Definitely not vintage... but could use some help

2012-02-27 by jquartic

Hi all,

I've been mostly a lurker on this group for a long time... its a great group. I've learned quite a bit about the vintage synths that I do have, but I have a question about a non-vintage keyboard that I recently acquired. It's a Casio Privia PX-330. I do some work for film projects, and occasionally need a lightweight full sized keyboard with internal sound for meetings, etc.

I acquired the keyboard with existing damage to the top of the keyboard casing. One of the function buttons was pressed below the keyboard casing. I'm not a keyboard tech... but am a computer tech. I pulled the keyboard apart, and there is a damaged board with a number of tac switches on it. The board has a hairline crack running through it, and only 1 function/tac switch on the board appears to work. I'd like to replace the board. The numbers on the board are M901-CNA1 A and N40A35B5 A30C5/A3C7/C7.

If anyone knows how I can obtain one new or used, it would be greatly appreciated. Functions on this board (primarily sequencer and rhythm functions) do not work. But the rest of the keyboard is fully functional. On the other hand, if this board can somehow be repaired, that might also be an option.

Thanks very much.

John

Hi John

I've dealt with Casio several times here in the UK and found them easy and
reasonably priced.  They will do spares and schematics.  I would try them
first.

Regards

Hi John,nice keyboards these,I've just bought one and its great.If you are a computer tech you probably know how to solder.I've repaired PCB's with hairline cracks in the past.If you can see the crack you will see which tracks are affected,just gently scrape the lacquer off the track either side of the crack until you have bare copper and then with a fine tipped soldering iron just run the tinned tip of the iron over the crack and this should bridge it with solder.Its worth a try as I don't think you'll get an old board as the keyboard is so new,and a new one would probably cost an arm and a leg.Regards Colin

Hello John,

Yes... nice good piano touch, good sound, light for a weighted keyboard and well built.

You could try to solder the cracked tracks and best also bridge them with thin wire strand.
If you could not manage this you could order new board through your local Casio agent; they could check and order it for you.
Here are your part details:

Code No: 10346445
Parts Name: PCB ASSY/CNA1
Specification: TK-RJM509707*001

Good luck,
Noel
