I have problem with Siemens X300. When I press the power on button the machine tries to boot but within 2-3 seconds shuts down and restarts the power-up sequence again, it keeps repeating until I forcefully shut it down.
The AC power supply only shows power light and battery light solid green, none of the other lights come on, 48V and 12V checked out OK on AC.
Also checked the DC-DC TPs:
All tested OK but TP11 and TP12 polarities are reversed,
reading:
TP11 +14.2
TP12 -14.2
I used the test reference from another posts by Anthony Ngo(Many thanks) but is this a typo or am I missing something.
Also can somebody please email me the service manual to masoodexch@gmail.com.
TP11 and TP12 voltage you mentioned are correct.
Follow these steps to troubleshoot and see if the symptom changes
1. Remove all transducers and boot up machine. Check if symptom changes.
2. Remove TR board and boot up machine. If the symptom is same refit it.
3. Remove RC board and boot up machine. If the symptom is same refit it.
4. Remove Hard disk and DVD drive connection. See if symptom changes. If it doesn't then refit them.
5. Remove TI module and boot up machine. See if symptom changes. If it doesn't then refit them.
Let me know after you perform all above steps. Then I will tell you whats the problem is.
Abhishek, checked everything you suggested in the sequence. no change at all.
I also checked and verified the TPs on the BE board, all good, also checked cooling fans, both work fine.
Any help is appreciated.
If the steps I mentioned did not change the symptom then its most probably a problem of RM (ETX or CPU) board which is attached to BE board. Let me know if that solves problem. Message me on abhi21687@gmail.com
I have a problem with acuson X700, when I was press the power on button the machine tries to boot but within 2-3 seconds it shuts down, we found problems in ac/dc power, after ac/dc repair the machine can not startup.
The AC power supply only shows power light intermittent green, none of the other lights come on,
48V and 12V checked out OK on AC.
Also checked the DC-DC TPs:
All tested OK, but TP11 and TP12 polarities are reversed,
I looking for a service manual for this model, but x300 service manual will be very helpful to me.
