Connie...your problem might well be the macerator --- try turning the screw on the beck of the pump (might have a rubber cover that needs to be removed) -- I've found this to be a remedy and don't have to mess with the wiring. Often paper or something causes the macerator to stick, and turning the screw takes care of it.
I replaced the analog TV with a digital in my 2350 before I got the 2552...it was fairly easy as far as mounting. However, because the dimensions are different, I had to add a piece of maple (the trim wood in that one) at the top. It really didn't look too bad. Unfortunately, I can't give you a picture, but you may be able to see it on the PC site under inventory --- the 2350 with "only 14K miles" assuming they show a photo of the interior. BTW, the replacement was a Samsung (same as the analog)...
