Before I had no problems on regular cable I would just pick expert 1 for the 480P but now i'm going nut trying to adjust it. The HD chanels seem ok except when there is fast action you see alot of squares in the scene .
Service menu access has been covered elsewhere in this forum,however altering the serial no and model no should have no actual effect on the tv or its settings.
I know this because,like you,i have had a mainboard replacement in my 3 month old 55" 6500 and i took issue with LG over the fact that my tv's ESN&model no were not the same.
Here in australia LG uses a network of agents to take care of service issues with its consumer products,not all of them in my opinion are competent,including the guy who came to fix my tv.
I dont know how it works in the USA or other countries but i would recommend you contact LG again and complain that your serial no and model no on the back of the set dont match the ones in the menu,it seems like your tech did'nt do his bloody job properly either!
Btw: your problems with hd cable will probably be the low bit rate of signal feed to your set and not the set itself, so blame the provider first
