I received this email from a forum subscriber and figured it would be best to answer it in a public format for the benefit of others who may come across these errors.
Following a power charge in the hospital building, our u/s began shoeing the following s:
signals on switching on:
CSC 28
FEB 28
FEC 28
FEC 80
DAQ 08
OC3 06
PROMLOAD 04
DPR 80
To start with, I'll need to know a few things -- was the system connected to a power conditioner/uninterruptible power supply/voltage converter (240-120v)? If so, have these been checked for proper operation?
Secondly, I need to know if the system is displaying any power errors. To find this you will need to remove the filter at the back of the ultrasound unit. Please see the picture below to find the 7-segment LED.
If a power supply is failing a number between 0-9 will appear in red on that display. Let me know what the number is and I can check the error code list. That will help pinpoint which supply is failing -- judging by all the scan converter error codes though, my immediate guess would be a scan converter power supply fault.
Could also be a board shorting out a power supply. Easiest way to check would be to pull some of the scan converter boards and see if the system boots.
Lets start with the power supply LED though, then go from there.
Even before you get to reply the last message, on opening the back of the U/S , the point at which power enters the machine was discovered burnt with at least two transisters looking burnt. This appeared to be the power entry point into the machine. Therefore power not entering enough into it.
can you advise

Can you send me a picture of the assembly that has the burnt out resistors? Or a part number, something that I can go off of.
You mentioned in your email that you would probably need a 'conversion unit'. Did you have a power converter for the system prior to the power surge?
