Howdy,

The touch panels use +5 and +12 VDC, and the control panel uses those voltages as well as the -12 VDC. The easiest place to measure those voltages is on the Power Regulator board. There are also LEDs and voltage test points on the rear panel of the DC power supply.


The problem might be due to one or more open fuses on the Keyprocessor I/O board. There are eight 3A pico fuses on the board. F8 is a spare.

If you need support or parts, Advanced Ultrasound Electronics can help you. We have most parts in stock for the HP/ Agilent/ Philips Sonos 5500 and 7500 systems.

If you have an ohmmeter and can do the mechanical work of opening the control panel, this is the way to check the fuses to see if one or more are open. Replace any fuses that are open (high resistance).

1. Loosen the 2 flathead screws on the underside of the front handle.

2. From the front of the system, lift the control panel upward while pivoting the top of it.

3. Pull the control panel toward you until the slide hinges inside the bottom of the panel are fully extended.

4. Lift the prop rod that is located against the rear wall and insert in lower left corner of the left touch panel.

Dear Jim,

This Yazeed, I'm Dr. Reda's son.

I'm an electronics engineer, I have checked the fuses you have mentioned and they all seems to be OK. Ive also checked the two fuses on the graphics board and they are OK as well.

As you know there is too many caps  on the bottom mother/main boards, could it be one of them that is cousing the problem ? now by visual inspection they all appear to be good i.e. no bulgy ones. what you think ? should I get an ESR meter and check them ?

We would love to get remote support from your company if possible as we are very far away.

Hello Yazeed,

I would suggest checking the +5, +12 and -12 that are used by the control panel. Those can be checked on the Power Regulator board in the E-box. You can access the E-box by pressing in on the buttons on either side of the user interface and lifting the user interface up. You should see a metal cover that has several Torx fasteners holding it down. Loosen those to remove the metal cover and you will see the Power Regulator board with a lot of test points at the top of the board. The metal cover should have a label showing the voltage that can be measured at each test point.

If the voltages for the control panel are OK, then I suggest replacing the Main I/O, also called the Keyprocessor I/O. It is part number 77921-60200, and AUE has 3 in stock in our USA office. Please contact us at Sales@auetulsa.com for a quotation.
