WMS BB3 not starting

[sakwilla]

Hi all,


I have a WMS BB3 machine and recently when I turned it on nothing would load (just stay at a black screen). I turned it off and on again to see if it would work but no luck and then trying this process a few times it would then actually load.


This happens now every time I turn the machine on. It always begins with a black screen and have to turn it off and on several times for it to eventually load and work correctly.


Can anyone point out some things I can look at or do to try and solve this issue. I took out the CPU and re-seated the video card and that didnt work.


Thanks in advance.

Did you ever figure this one out?  I am having the exact same issue with my Blade.

Both the CPU and the GPU cards fail in those causing no boots. Bad monitors and button panels can caused failed boots. Lastly they are known for eating SSDs but it'll boot into a system halt failure for that.
All of this depends on having a good PS, like all machines.

Also do you hear a speaker "pop" at all? If you do then the CPU is booting but your video card is bad. Also do you see all the lights on like normally on the cpu?

Yes, everything lights up fine. I just don't see the picture on the monitors.  I also noticed that the Tito is not getting power and its plugged into the USB hub under the top shelf.  I swapped another machines CPU into this one and it works fine.  So I have narrowed it down to the CPU being the issue.  Now I just need to figure out what part of the CPU is the problem.  I do see the green lights come on inside it but it just wont boot.  I removed the ram and cleaned it but no luck.  So maybe it is the video card.  Thoughts??

Ah that... A reballing or reflow might fix it, never have done that, but it is the thermal cycle that caused a i5 to sperate from the adastra PCB. I had a machine that would boot sometimes, fail at loading the intel HD graphics driver sometimes, and not boot at all other times. My best determination was broken solder balls under the i5 chip

If it is the video card  reflow will fix it. Maybe even the reglow of i5.
