Well...
I'm making progress.. undid the ribbon connector & reseated it tonight... it's improved markedly... not 100% but, definitely better..
Next step will be to remove the ribbon connector again; give everything a clean & reconnect...
Possibly do a factory reset/firmware reload just in case the display chipset has corrupted somehow...
I've also received some tips on improving my keypad connectivity other than what I have already tried so; some internet shopping to be done for either silver conductive paint or, a keypad restoration kit..
After I've exhausted these somewhat cheaper alternatives & see the results I will ponder a replacement.. they aren't exactly a cheap item...
Cheers...
Hopefully someone might see this for tips at least should they have a similar problem.. I'll continue to update as the fixes I try work or otherwise...
