Have this hospital set in that continually changes channels than shuts down. Win-tips says the board that has the phone jack plug. I need to know the part # for that board. There was a reference to the zener diodes, but they are good. I've had Union research the part # & had no luck & the hospital is getting anxious. TIA Greg Gregory B.
