I bought my dad a KDL 32L4000 for Christmas and we're having trouble getting it to pick up OTA signals. We have a hi def antennae on the roof and my tv (Samsung plasma) and another tv (Sony HD CRT) picks up all the HD locals but the new LCD doesnt. When we set it to search for channels it only finds three "digital channels" and none of them look that great. Is it something with the tuner in the panel? Should it be able to pick these channels up? Thanks.
