I am wondering if someone can help me out. On booting up my iu22, it fails immediately with a black screen. No beeps from the UMB, with the UMB display sticking on boot up at 2A.
I have reseated the RAM, and changed DSC, AVIO and SPD from another working machine.
I swapped in the UMB from the working machine and got a similar outcome, with it sticking on 2A.
Any help troubleshooting this would be much appreciated.

Philips iU22 E-cart. I performed a front end bypas, and the UMB returned to a normal state (AA), and I got the normal beeps through start up, but I only get a black display. I have swtiched the video cards which did not resolve the issue and pluging in an external monitor is also blank. The iu22 monitor works if plugged into to another iu22, which I did to test if it was working correctly. Any ideas?

Replace the power board that sits behind the umb on the back wall. Had the same issue and replacing that took care of it.

Boot to black either comes from the video cards or the NAIM. The system clock resides on the NAIM which will cause this issue. If you have a donor system, grab the NAIM and try it. That would explain why you were able to boot with the Frontend Bypass….
