A friends DA7 has some trouble with two of the faders.
He's tried everything (including fader calibration, hard resets, and cleaning) without luck.
It seems that his cat got sick on the board and altered the condition of faders 2 & 4.
After performing a search I found that the subject of replacing the faders was brought up previously.
If anyone who has access to the manual would be kind enough to send me just the section on fader replacement I would be very grateful.
TIA,
Paul

I'm afraid there isn't a section on fader replacement in the manual.

There is a circuit diagram for the Fader Driver board PCB. All the faders mount onto this board.

If you are having probelms with Channels 2 & 4 then I would suggest removing faders 1 & 2 (mark them first so you know which is which) then put fader 2 into channel 1 position and vice versa.

If channel 1 is now playing up but channel 2 is OK, you have a fader problem.

If Channel 1 is still OK and channel 2 is still faulty then you could have a driver IC problem.

The driver IC's for channels 2 & 4 are strangely enough IC 2 and IC 4. You could swap these for 1 & 2 again to prove them. (I can't tell from the manual if they are surface mount devices, which would be hard to remove/replace without speacial tooling)

Part Numbers for Driver IC = YWTA7291S
Part number for Motorised faders = EVANMAP01B14 or
EVANMEP01B14 (Two types listed although I can't see what the difference is)

Panasonic parts can be obtained from:

Feline Barf is acidic and may have damaged the PCB. That is the worst scenario I can think of.

Good luck

Was it a tiger, by any chance, Paul?

I believe that there's a left and right fader.

I'd check with a RAMSA DA7 service center to be sure.

There's probably a diagnostic self check function for finding a bad fader or I.C. that they can step you through.

There's a link to Panasonic Service on this website.

Good luck,
