    Hi Stanley and welcome to Electronics Point :)

    I've edited the thread title to include the name of the device you're repairing.

    What is the model number?

    What are the fault symptoms?

    OK it looks like it's a 3M model 101 bridging video switcher. Have you tried Googling those keywords?

    There doesn't seem to be service information available.

    If you want, upload some photos of the circuit board. Be sure that all of the part numbers on the large ICs are readable.

    yes I did Google it and found out the unit is to old there must be
    manuals on how to repair the unit. I got my EE Degree from USC
    in 1974 and I worked on repairing TV's back in the day
