problems with my d8b

[Maloik]

Hi to all!

My d8b has some problems I can't solve.
Sometimes when I switch it on all the lights are just flashing und the faders are twitching like "toc toc toc" and the console does not boot.
When I move the data cable several times it works. At first it just happened when the console was turned off for several hours, but now it also happens while running. Then I have to restart the desk and all the changes I've done till then are lost....it's annoying.

Due to the fact that it works when i move the data cable plug i thought it would be some cleaning problem...so I opened the desk and cleaned all the ribbon cables and so on but no bettering.

Has anyone some ideas what it could be??

Thanks a lot in advance

Cheers
Tom

I assume that you also checked the Data cable pins etc. both ends.

Hi phil
Yes I already checked the data cable with a continuity tester. and everything looked fine.

This happens everytime you move the Data cable?

[Maloik]

No, but most of the time i can fix it by moving the data cable.

When the problem appears i turn off the desk and move the data cable ( sidewards, like shaking ) and usually i can boot again but not always.
I have no idea what this could be. I already cleaned any connections concerning the data cable.

It looks like some solder issues but i have no idea where and can´t find it.

I can't remember if the connector backs come off so you could check for dry joints etc. Another idea is to check continuity with someone else wriggleing the cable.

The fact that movement of the cable causes a make/break in the circuit? Which end are you moving? I think from memory that the connector inside the console is behind the rear boards, i've had these out, it's a bit fiddley as they have to be maneuvered, there are tiny capacitors around the edge that can break off...I know from experience.

hi again!
I cleaned all ribbon cables and faders the last 2 days. There's no way to check the back of the data connector in the console. there are just 2 ribbon cables coming out of the connector and I didn't want to break anything by opening it.
But no problem until now.I will replace the data cable with another one if the problem appears again. I will report if something happens.

But there is another issue:
Since a couple of months I have some trouble with five sticky faders....haha sticky faders...deja vu number xxx.... i used to deal with it because the only thing i found on the forums was to replace it.... but as I opened the console this weekend I suggested to clean all the faders....so I opened all of them and cleaned the carbon boards, bands, detectors of all the faders. 22 faders now work like new but two on the second fader unit (no 12 and no 16) are still sticky.

Is there any way to repair the faders on our own? did I miss anything? or do i really need to get replacement?

Thanks again
Tom

I expect you've done a few fader calibrate's.

Phil

[Maloik]

yes...4 or 5 times

A friend of mine has had sticky faders for years but what he does when they stick is stop transport and then press play and they clear.
