My 128 XP/10 starts up- goes through its screen sequence of different colors and flashing bar with the Acuson copyright info but stops with a non blinking block (cursor). There is no sector image, date, facility info etc. just one non blinking block (cursor) at upper left hand corner of screen. Have you come across this?
Couple of questions: how long have you had the system? is this the first time its done this?
I have come across this a few times, and from memory it sounds like an issue with either the OC3 eproms, or a dead battery on the CVC. Although, since you don't get any power on errors it might lean more towards the OC3.
How comfortable are you with opening up the system and checking out some things for me? Also, do you have a voltage meter?
Hey thanks for the come back Todd.
Had the system about 7 years. First time the machine has done this. I would be fine doing some minor surgery with a screw driver. I can get a volt meter.
Underneath that top panel is a silver-colored plate thats bolted down by about.. 15-or-so screws. loosen those, slide the plate over and lift up on that. Underneath that is probably a really old and moist foam cover, if it isn't there... or isnt moist and old... consider yourself lucky. Underneath THAT are all the Scan Converter PCB's, one of them being the CVC (common video controller). The board is located near the back of the ultrasound machine, it should go: CSI, CED, CVC.
On the CVC are two batteries, they're about as round as a quarter, and 4-5 quarters thick, with 3 prongs that are soldered to the board. The top two pins spit out the same voltage, with the 3rd pin being the ground. With the system OFF, and unplugged, take the volt meter, switch it to DC .. and measure the battery. If it's in the 3.6-3.9v range... you should be alright. Anything lower than that and you risk losing all of your preset data, encryption strings, and possibly any user-defined calculations (option 1, 2, and 3 are all user defined).
If the batteries are dead, that could be one of the reasons for the system not booting to imaging. If thats the case, it probably needs some power to the RAM chips on the CVC before it can fully boot. My recommendation would be to leave the system on for a while (10-15 minutes), then press the RESET button (located behind the white door under the monitor), and see if it boots to imaging. If it doesn't, then it could be an OC3 problem... but lets start with the CVC.
Thanks Todd for the detailed procedure. I will need a couple days before I get do to this. FYI I have tried the reset button after the machine has been on-- it still ends up with no image on the screen. Will let you know what I find.
Followed procedure. NO reading on voltmeter for either battery. So it seems dead batteries on CVC are the problem. Can you guys redo the batteries on this CVC board?
two ways we could do it. sell you 2 batteries, send them to you, and you install. or send us the CVC board, we install two batteries and charge for batteries + labor.
shipping would probably be more expensive with the board, but then the burden of responsibility falls on my shoulders. i guess it comes down to what you're more comfortable with doing.
as far as pricing goes, i'd like you to email my sales partner, his name is Angel. his email is aurquijo(at)u-d-s(dot)com
i'll explain the situation to him, so all you have to do is ask for pricing of both options.
Hey Todd thanks for walking me thru the diagnostics. I 'll get in touch with Angel. Do you have a test mule you can pop this board in after replacing the batteries to make sure it's good?
I have a machine here that will work, but I still have some other concerns about your system. Going back to your first post, and other posts about it still not booting up even after leaving it on for a while. The CVC battery thing could be one of a few problems.
If you have a chance, could you look on the OC3 board (it's the one closest to the monitor in the same card cage as the CVC) for some labelled chips/EPROM's. The sticker will say "OCWARE" or "OC3WARE" and there will be 4 of these chips. If the system has it, we can try to run manual diagnostics and see if the system has any other board problems.
Also, on the back of the system there will be a black vent/filter, behind that is a 7-segment LED which is usually blank... but if you have any power issues it should pop a number on that display. I've included a picture of what it should look like:
Speaking of the machine that would work... I turned it on this morning, and I had a bunch of internal errors, and a power supply error.. troubleshot it down to a Receiver board, but when the damn thing finally booted... I had the same problem you did. Black screen, white cursor, no date and time, nothing. So I left it on for about 10 minutes, came back and reset it... same thing.
I tried changing out the battery, and still nothing. Ended up swapping out the CVC board with one I had spare from a parts machine, and it boots now.
I hate to say it, but you could have a dead CVC. I'd be willing to test the one you send, replace a battery and see if it's the board or a battery issue... but if it's not the battery, how would you want to proceed?
I am sending my board to you today. I would first test the batteries on my board to make sure the batteries are dead with your tester. I would then replace the batteries and then test the board functionality if possible on your machine. If my board is bad, do you have spares? We should talk if we get to this point.
I'll check it when it comes in. We also have most of the spare parts for the 128XP10. All the boards, but we're short on monitors, and a few power supplies.
Regarding the OC3 board, mine has the four OCWARE chips. I checked the 7 segment LED during attempted start up and did not see any error code numbers. I have shipped the CVC board today, suppose to arrive at your door this coming Tues. 10/27.
Sounds good Tim. I'll check out the board, and let you know what the issue is.
When you get everything back up and running I'll email you some information on how to get into manual diagnostics and run a Preventative Maintenance test.
Hi Todd,
I use this topic because I have similar problem with Acuson 128 XP/10. The machine starts up to non blinking cursor on the upper left hand corner of the screen and date and time on the upper right corner of the screen.
I still have not measured the batteries on the CVC Board. Pressing the RESET button after 10-15 minutes gives no results. There are no errors on 7 segment LED.
I performed PM tests (7 tests failed) and the STAT result is:
21 OC3 IC-to-OC Fetal M-Mode Int
23 OC3 IC-to-OC Fetal M-Mode Eof
24 OC3 IC-to-OC Last 2nd Interrupt
27 OC3 Scan Cvtr Int. System
EC SCNR VDT and SGD
EF SCNR RCVR APD test
F0 SCNR MXK test
I'll be grateful to have your advice.
Thank you.
Stoyan
Hi Todd,
In addition, I'd like to inform you, that I've measured the battery voltage on the CVC Board - 3.649 V.
At the very beginning the clock on the upper right hand corner of the screen works for 5-6 seconds. After that it stops and it's not possible to use any button combination on the keyboard.
TEST-Code-Shift-V could not be used also.
Only RESET is active, but w/o success.
I checked all the IC's on sockets if they are properly fixed - o.k.
Best regards,
Stoyan
Based on the PM results it looks like your OC3 is failing some functions that would appear to prevent boot-up. The link between the IC (input controller) and OC (output controller) is vital to the machine starting correctly.
What you can try though, is to move the OC3 from the slot that it is in, to either the slot in front, or behind it (depending on where it is in the card cage).
For some reason or another, the OC3 can fit in the first slot, or second slot of the scan converter. For instance..
Spare
OC3
CMB
or...
OC3
Spare
CMB
Try swapping it from one slot to the other, then boot the system and see if it gets anywhere.
As for the CVC batteries, 3.6 is decent, but still on the low side. If you can get the system up and running I would recommend copying down all the information off the Encryption Strings page, as well as any presets/applications you wish to keep.
Let me know if swapping the board slots does anything. If not, you may end up needing a new OC3. As for the SCNR tests... could be a bad XMT or RCV somewhere. Once you're able to boot to imaging, we can troubleshoot those problems, or... if you're feeling adventurous:
Go back to where you performed the PM test, but this time.. at the $ symbol, type : XEF (press return)
That will run the SCNR RCVR APD Test by itself, and will give you a more in-depth look at what channels are failing. Once I know which channels are failing, I can tell you which board in the chain is causing the issue. Do the same thing for the SCNR MXK Test (which would be: XF0 -- return).
Hi Todd,
I checked the OC3 on the other machine - o.k.
I checked CVC also - it was w/o Encyiption Strings but anyway there was an image on the screen with error messages.
Just one question about the error message "Prototype System Software. Not for Diagnostic Use".
If I change the batteries on CVC it should disappear? I have this error message after changing the batteries, non blinking cursor, date and time (clock stops after 5-6 seconds).
Regards,
Stoyan
All that message is a bunch of text. It's probably something they had set up for the factory, pre-market probably. To delete the message on the screen -- hold down Code and press Delete (should be just above Code on the left hand side of the keyboard).
Changing the batteries on the CVC won't bring your encryption strings back. Until you have a valid set of encryption strings, you will continue to get that message.
The clock thing could be on the CVC board itself, although.. when you replaced the batteries, did you replace one at a time, or did you take both off, and then replace them? I've had issues with the onboard battery-backed RAM going haywire when both batteries are removed completely.
That could be the reason for the system not booting past the cursor/date-time.
Hi Todd,
The error message "Prototype System Software. Not for Diagnostic Use" appears every time I start the system. It doesn't matter if the transducers are plugged or not.
There is only white cursor on the upper left corner, data and time on the upper right corner on the screen and the error message. The clock stops after 5-seconds.
There is no image, graphics and alphanumeric information on the screen.
The buttons on the keyboard are not allowed and it's not possible to use combination CODE-SHIFT-V-TEST keys.
I'm going to check the minimum hardware configuration (CVC, OC, IC, MMB) installing them together on the other machine.
As I wrote you, when I checked CVC and OC on the other machine there were some error messages, but an image screen with graphics and alphanumeric information has appeared despite of all.
Regards,
Stoyan
Hi Todd,
I checked the whole Scan Converter Box, incl. Scan Converter Motherboard, on the other unit - works properly.
I checked the flat ribbon cables b/w Scanner ans Scan Converter - o.k.
Power Supply Voltages - o.k. - no error message on the 7 segment display and measured values in range.
Despite of all, the problem is still there - the system hangs up 5-6 seconds after starting initialization. The clock stops ( no image, only cursor, date and time on the screen) and no keyboard button combinations are possible.
In my opinion, the reason is faulty communication b/w Scanner and Scan Converter. The corresponding boards in Scanner (DBR, SCP, MEX, DCC, STG, TRM) were checked - o.k.
So, finally I'm going to check the SMB.
Best regards,
Stoyan
Hi Todd,
In my previous mail I missed to inform you that after I changed the batteries and entered the encryption string, using the other machine, the error message "Prototype System Software. Not for Diagnostic Use" does not appear anymore.
But the system "hangs" w/o any errors on the screen and 7 segment display.
Next few days I'll check the SMB, as I wrote you.
Best regards,
Stoyan
Hi Todd,
Finally, I checked the Scanner Motherboard SMB and the same problem appeared on the other machine – the system just “hangs” w/o any error messages on the screen and 7 segment display.
Only white cursor on the left top corner, date and "frozen" clock on the right top corner on the screen.
I checked the pin connections of the most important SMB slots – o.k.
SMB is a 10 layers board and I suppose that there is some bad track connection(s) which could be found only if I have the wiring diagram.
Now I’m looking for SMB, , P/N 10362, but w/o success.
Thank you very much for your help.
Best regards,
Stoyan
