Curiosity drives a lot of 'why', I cannot tell you how many instances of this basic tenant involves my desire to help. In this instance, I don't have an answer. I wish I did, but there are way too many variables to even postulate a concrete theory. Something causing a concern like this, I would just move to another hardpoint. In the back of my mind (like Dave) I would be bothered until either it gets moved far back in my priorities, or I just move on. Electronics are just too 'unpredictable' to troubleshoot because of way too many variable that are unknown or unavailable to duplicate. As an example, my attempts to troubleshoot systemic A/C control head (re-occurring) issues. I have been unable to acquire a defective head donation from members (even if I reimbursed for low bulk cheapest shipping). Not to digress, just to point out that any situation presented for analysis, there has to be some give and take involved. I applaud 180's questioning 'why' but my experiences in these areas just cannot explain his specific situation. In my example, I have centered on a specific clue (only a start) for the A/C head issue but have (since asking for a donated head unit) only had offers to buy a defective head (as a cost share to help a member reduce his/her repair bill?) or no offer at all. This kind of response makes me feel like any contribution offered by members isn't appreciated by a lot of members. Sad to say that but regardless, I will (like many others) continue to help those who appreciates the free information available to all. On one more note, I have the feeling a few 'new' members, are actually reselling crossfires, and are stuck with something wrong with it and are wishing to fix it for the next owner. I actually applaud these folks trying to sell a car that's fixed but have a funny feeling about how they go about the way they are getting it fixed. either way, I hope whomever buys the car gets it fixed before they pay the monies asked. In the end, those who try to help do so without any hidden agenda.
