Backlight flicker - a fix for some?
- As I mentioned earlier, my OB was developing backlight flicker. I was
apprehensive, but I decided to try Ian Butters method as described in
his message on 2nd July 2003. I can confirm that it is a good idea to
have a friend or partner to assist holding things while working
I add a few notes here for anyone else doing this:
The 5 x screws at the bottom of the rear panel and 3 x screws under
the ribbon controller are smaller than the screws on the end cheeks -
ideally, you need a smaller Philips screwdriver for these.
The rear panel screws have washers as well (more parts to lose!)
The keyboard stays with the base, and the way the wires are laid out
inside means it is best to open the front of the synth and keep the
back edges close together.
The wires connecting the keyboard to a circuit board in the lid look
fragile and vulnerable, so be careful.
The circuit boards themselves look quite sturdy. If we still had
those photos posted you could see that . . . (where has our files
My connector did not seem to be very loose, though it had some
initial movement, before its catches engaged. It's like a regular
Molex connector and comes off fairly easily (i.e. I didn't need a
screw driver to prise it apart), but mine certainly wasn't falling
off. I found it hard to believe that it was causing the flicker, but
I used a piece of Duct tape (for that professional touch) to secure
the plug in its socket, just by wrapping it around.
I put it back together carefully, and the flickering has stopped (to
my surprise and delight). I'm sceptical that it's a permanent fix
especially after hearing about Tobias' experience, but am grateful
for small mercies.
Has anyone noticed that the rubber feet leave stains on furniture?
- Is it 100 percent sure the probs
are not depending of:
1. magnetic fields (speakers)
2. electric fields (powersupply)
3. earth radiancy ???
It is significant, that the probs
only arise to some users sometimes
in repetition !
Make a change first (position, room, ...)
to exclude this first.
