After the FEB 2009 cut over, your "OLD" tv will nolonger be able to receive OFF THE AIR signals as they will be broadcast over different frequencies. HOWEVER, as long as you subscribe to CABLE or SAT TV (Dish/Directv/etc) your old TVs will continue to work as they always have -- (because the signal is not OFF AIR) but you just won't have an HD picture.

Follow the power cord (set unplugged) into the set as it goes directly to the main fuse (should be 6.3 amp) and see if it is good or bad.

6 blinks is usually associated with failure of the horizontal deflection amplifier - which shuts down the high voltage system as well.

The repair requires testing to determine the exact parts that have failed. There are, for example, a few hundred parts and a section of the Jungle IC chip involved. So, repairs could require something as simple as replacing some inexpensive passive components OR as complicated as replacing the jungle chip (very expensive).

most of the time it's the horz. transformer and transistor.
