questions about pre-amps, signal reception

I haven't been around here for a while but, whenever I need help, I know where to come. Thanks to all for previous post replies.
My issue is:
About two months ago, I seemed to loose signal strength on some stations.
I have a nice winegard deep fringe antenna at 30' with a rotor. I'm 35 miles southwest of Philly in Delaware and get most of my channels from Philly.
Problem is that two months ago, reception of WHYY (12-1, -2, -3) and Channels 29-1,29-2, & 29-3 seems to fail, especially during the day. I've tried to move the antenna to get a better signal strength but, it just doesn't seem to work well for either channel.
The rest of the 35 or so channels are just fine.
Another issue that may or may not be related is that when I watch the signal meter on the TV, it fluctuates all over the place and rarely locks in like the stronger channels.

The preamp like the rest of the setup that I installed is about 2.5 years old. The preamp is in the attack, having run the coax from the antenna, through the attack to the far end of the house and then down to the basement splitters.

The only other room in the house in which we have a TV is the MBR where we have a newer model flat screen and it doesn't seem to have this weak channel issue.
The Big Screen, on which I have these issues IS the last of the projections (2006), but again, there were no issues until recently.
Thanks for any suggestions.
