This is an ugly update from prior post
In the prior post, a 10dB inline coax amplifier added to solve video corruption (partial lock) problem on one tuner (2) on one channel (40-1) for over the air local broadcasts.
An unexpected result was new one channel (3-1) video corruption (partial lock) problem on the another channel on the other tuner (1).
The reliable and stuffy pseudo 1080p 47LX196 Toshiba television's signal strength meter says 3-1 signal is strongest of received, and 40-1 is the weakest received. Itself has no problems locking on all channels with or without an inline coax amplifier.
I sure could use some suggestions or help here. Is there an internal RF problem with the RF splitter? Is one of the tuners out of whack? Is my HVR-2250 broken? Are all HVR-2250s Broken?
