OK all. I have replaced all three optos, two on the main board and the one on the vertical board, and....disappointment. No luck and nothing has changed. Haaa
While looking at the CM6800 IC, it appears, and it had been mentioned before (by kellys_eye), that this should be one of the components replaced. It does seem to have information in the description and explanation for the operation of the component that could affect the issues I am having. The problem with that is that the exact same item is not available in the US. Well with the exact same markings anyway (CM6800UBX), so I have that ordered from China. Ten of them, actually, because 1 was not enough. Haaa. Estimated 12-30 days, Yikes!!
There are a lot of CM6800 components with other digits/letters after, and looking at their datasheets, I am really not finding much of a difference, so I am wondering if any CM6800 DIP would work? Is it common for component manufacturers to add digits to a chip just so another manufacturer (DVR, Stereo, etc.) can claim it is a proprietary component?
While I am waiting for it, the PS is being sent back to the owner to test in the actual equipment it was made for, to see if the load from that equipment will activate the voltage it is supposed to supply. I will let you know and I am hoping it doesn't blow all of the work I have already done with it. Can you tell I don't like to give up?
Once again. Thanks for your help so far.
