Hi, thank you for contacting JustAnswer.com. My name is***** will do my best to provide the right answer to your electronics question. I must apologize for it having taken this long - we had a backlog, and a server outage today also.

I advise you to get a service manual for this particular model - if one is available. It will guide you as to what points to measure with a voltmeter, and what each measurement means, to some extent at least, as well as other things like accurate parts # lists, and so forth.

Now if there is no power, there may be any number of problems anywhere, really, if it is as persistent a problem as you say it is.

1. you might have a shorted board, loading down a voltage line, thus preventing the Main Logic board from initializing and turning On the whole device.

2. you might also have another sort of problem, but (1) is most likely.

Let me know a bit more, and whether you'd like me to do a search for sources for a service manual (which might be free, or might cost up to $20 or so), in Reply, and I will help you further.
