faders problems

[budman65]

scrapped the startup file. still nothing. faders lock as soon as the power is turned on. I left it on for 10 -15 min and then thought I would check fader boards. 1-8 was hot to the touch, 9-16 a little cooler and 17-25 cooler still, all passed the sniff test. There were no obviously blown components on fader board 1 - 8 which I removed. I am wondering if if the 9 - 16 board is toast along with the 1 - 8, or if there are larger problems lurking still?

a good way to tell if the 1-8 board is toast is to pop it in the 9-16 slot. If the problem follows it's the board, if it doesn't then there is something else going on.

You could try a re-format of the HD then a fresh install of the OS. Or a new drive altogether.

I took the 1-8 board out. Then i cranked it up to see what would happen. The response was the same no automation of faders and they would all stick when changing modes. I think I am going to have to chunk it. It will cost more to have repaired than buying something new.

The faders have always offered resistance for a second or two after changing banks. It's normal.

I know. I have had this board since 03' and have had good luck other than the occational flip for reseating ribbon cables. The resistance I am refering to is to all faders when changing modes that does not stop at all on board 1-8 and you have to move the others up and down to release them. Changing modes causes the problem to happen over and over. I changed the fader boards around like someone suggested and the stuck faders with constant downward force followed board 1-8. It is that the quirkyness of the other faders. No motor control from the OS etc.. that has me worried about sinking a lot of money into this board.

So you are saying if if swapped 1-8 and 9-16, the problem would move to 9-16? I am just trying to clarify what you mean.

[budman65]

Yes, one problem seems to follow the origional 1-8 fader board. The issue is the fader motors are constantly pulling down (no way to release them). I moved that board into 9-16 position and the problem followed it. However, there seems to be other fader issues going on as well, such as, no fader movement (any fader) when the on screen faders are moved with the cursor. If you change modes all faders reset to the bottom and are all stuck there. They will not matck what is on the screen for said fader placement in each mode. You have to manually move the faders (other than the "bad" board because they are stuck and fly back to the bottom position no matter how much they are moved) to release them. Usually moving them up and down a single time with accomplish this. But again you change mode and it goes back the same thing again. I have reseated ribbon and cleaned connections with electro contact cleaner. Reformatted the hard drive. Everything that has been suggested I have tried at least twice.

The 1-8 board problem definitely sounds like the IC fix is required. The others could be rail caps. First thing before taking those measures would be to check your power supply voltages and make sure they are correct.

Yep, thanks Peter. I will try that next. Don't really have the electronic skills to go far beyond that.
