Hi, I am going to be vague for this first post.Please excuse me.
A number of folks have very recently purchased defective AV receivers from a certain well known manufacturer. Since the manufacturer does not publicly disclose the cause of the symptoms owners are experiencing, much speculation has occurred as to the cause. The speculation I refer to is on a thread in a forum for AV enthusiasts. Since the repair involves a 40 pin ribbon cable and its associated connectors, one poster claims to have inside information as to the cause of the failure of these components. His claim is that there was an acidic gel applied to the PCB and connectors that corrodes the cable and connectors. Not knowing of any gel that could be left on a finished product's PCBs, especially in the area of a connector, I question this claim. So, my question is, does anyone have any explanation as to how or why or what this gel might be? And is it a feasible claim that there was such a gel? To me, the claim is extraordinary and leaves me with more questions than answers.
Thanx in advance. Any help would be much appreciated.
