You might look at the housing and insert's installed in it. For one there are different flavor's of housings over the year's and the bonding plane's, which would make contact with the module maybe located in different locations. Take a 1gig stock housing and place a few older generation housing's side by side and check if you have the same pattern.
Also check that the 1/4 round ground mesh in the lower left hand part of the housing is still in tack. It could have been pulled out with the last module change.
Also make sure that you have 15amp inserts in the housing. You may have a few 10amp inserts which will work to a certain point. If your closer to a power supply your housing will get very hot until failure causing an outage. Some techs will just replace the mod quickly without noticing these insert's. Fair bet that someone will be back out at the same location for the same reason. Look for return trouble calls that might point to a location that has been visited more then once for the same reason. Try to find a trend.
you might look and see if there is heat sink on the housing to module contact point. Also if you do have a spare return hybrid, you might want to remove the damaged one and see if there is heat sink behind it? If not place heat sink to the back of the replacement hybrid and place back into the module, then place the unit back in the same location to monitor.
Another idea is input power into the hybrid. You might check to see what the input level/power is for this chip? Level has power and most returns are padded in the common return output pad slot after the hybrid. If you have a high output return hybrid you might think about padding before and after the hybrid.
Just a few idea's, hope this helps
