    Fair enough ~ as you can appreciate in forums such as this, one really doesn't know the expertise of the person on the other side of the conversation, and if they can interpret IC datasheets down to component/PCB level and find the supply resistor TVguy mentions (which you head for after discovering no voltage at the IC supply pin(s) for example).

    I think of it like this ; every tech when working on stuff like this, does a visual inspection, and coming to forums like this, every tech trying to help you has this deep down yearning of 'I wish I could see the board for myself' ... I had a recent example of 'the board looks fine', but when I saw images of it, I could make an educated guess it'd be a specific IC I noticed, due to the fact I know what the failure rate of that device is. That's not the case here, but I've just obviating that sometimes 'nothing obvious' can be somewhat obscure
