Mirror Servo Board

Hey,

My VB has a faulty mirror servo board. I have been looking for a replacement for ages and none seem to pop up on ebay or anywhere else.

I am wondering about the feasibility of repairing the one I have. Am I likely to be able to find the ICs on that board or are they likely to be custom? Is there a chance it could be something simple like caps?

Does anyone know if there are suppliers that have any stock on VB spares? I am looking for a servo board and I am out of ideas where to search.

Hi All,

I am looking for a known working servo board for my VB as my one is faulty. If you have one to sell, please let me know.

Much appreciated.

Hi @RunnerPack,

I have checked out the continuity etc and so my conclusion is that the servo board has a problem.

If you have a spare one you could sell me please let me know?

I'd like one of these if you are still doing them.

Hi @RunnerPack,

After all this time I eventually acquired a known good mirror assembly from Japan. With this connected in has exactly the same problem where one mirror does not stabilise.

I will replace the caps and check connectivity as my next step but my gut is telling me something more serious is wrong with the servo board.

If you do have one for sale by any chance I would appreciate it.

Hey RunnerPack,

Thanks for replying, much appreciated.

Just to be clear, when you talk about "disconnecting" things, you're talking about the mirror galvanometers, and not the LED display cables, right? The two systems are independently controlled by the VIP.


Correct I am referring to the connectors going to the smaller board in the nose of the VB not the ribbons going to the displays.

I will open it up and give it another clean, and recap the board they are connected to and let you know how I get on.

If that does not work out and you have a spare board that would be hugely appreciated!

Hi,

I have a problem with my VB. When it fires up one of the mirrors (LEFT) vibrates and hits the stopper making a noise. The other (RIGHT) seems fine.

I have dismantled the VB partially and blasted some compresses air through the optical sensor and checked for any physical obstructions (both suggested elsewhere).

If I disconnect the side with the problem (LEFT) the problem switches to the other side.

Interestingly if I switch the Left and Right ribbon cables the problem remains on the one on the left indicating the problem is probably not with the mirror / optical sensor / solenoid set up and more likely to be on the main board???

All the caps etc looks to be in good shape.

I do not have an other one to test with :(

Any help appreciated.
