I searched the forum posts and did not see a solution to my problems so I thought that I would post it here.

I have a HP CPTOH-0602 (ek429aa). One day it just shut off. I took the back off of the unit and plugged it in. A blue light turns on one of the boards as well as the red power light. I turn the unit on and I hear a click then another blue light comes on the same board. The power light turns blue (can still see red) for about 10 seconds and then it "clicks" off. During this time there is no audio or video. I know that these units are notorious for having problems with their control boards, but I would like to pinpoint which board I would need to order and replace instead of just throwing money at it. There are two sets of fuses that I can see on the unit. One pair on the left hand side ( that are clear) and both of them are ok. There are also two white fuses on the right hand side that appear to be okay, but I can not see in them because they are white. I am including pictures of the back of the unit as well as a link to a YouTube video that shows what happens when I turn it on. Any help would be greatly appreciated.



You may have to copy/paste as it is not allowing my to put a clickable link in this post or images for some reason.
