Replaced the lamp. Tried the instructions to reset clock... pushing -vol on TV, and split, on remote. Hold and hold and hold... nothing. Does not reset. Probably isn't factory remote. BUT, it's a panasonic remote that works 100% on this TV. Now, is there a way to do... basically a complete factory reset?. without the original remote?

First make sure the TV is off. Then hold the volume down (-) button on the tv, and the split button on the remote.

Otherwise factory resets on Panasonic TVs is usually done by holding down the volume down (-) button on the TV, then holding the menu button on the remote.

Thanks SO much. :)
