General Discussion / Re: Black Vertical line centered on Display Huntron Tracker 2700

Never heard what the resolution was for the display problem. Maybe he will respond here.

So what is it a loose connection or new LCD panel required?

Hello David
Thought you might find the attached DSI 700 to PC Cable Interface diagram useful.

Hello David                                                                                                                                                         
Hope the attachment from the DSI 700 User's Manual helps.
Any good foot switch from an electronic component supplier would do the job with the appropriate size jack plug.

I believe the foot pedal diagram has been posted on the Forum before. I will look around and reply more.

Edit: Looked at the DSI700 information and the foot pedal was a simple two wire switch to a headphone style jack.

Hello forum friends, any of you can provide a diagram for me to build a pedal for my DSI 700 scanner.

The "good" was repaired. It was a 1k resistor I don't remember wich one but I think it was a reference voltage or something

Sounds like capacitors that have developed high ESR on the low voltage P.S.U.
Have you a meter to measure ESR? Their almost as good as a working Huntron!

I am guessing that a trace or via got damaged during soldering or removal. Take a close look with a good magnifier or video microscope.

Unfortunatelly I couldnt repair the boards. The one that was shorted I found the sine wave chip shorted (+5 -5) but the other 5v short i couldnt find.

The board that was good before still hasnt been fixed. I replaced the lf412s and the high speed buffers.
I ran the diagnostics and offsets but i still can have a good signature.

On the 200mv 3v selection the display is crazy with random noise.

At 5v 1k I can start seeing things. The oval shape is now almost a flat line but it is still a ellipse/oval/circle shape like I was measuring a capacitor.

What could it be? I can't understand why it went bad just by removing a pair of ICs and putting it back even after I replace them for brand new ones.
