Welcome conard, I hope you get your back flow prob. fixed. I too saw how to change out the CRT tvs. on this site. I was curious to know if yours were old units to prompt the change, or did you just want new flat panel 16x9 format tvs. I have been advised to wait till "they're broke" but I'm sure they're way heavier too.
Where "THUNDER" rolls, and Lightning strikes, we'll have great days, and peaceful nights.
