YES
NO
A DTV signal (available in the selected channel) is
locked.
There is no DTV signal for the selected channel.
Some troubles exist on tuner and/or VSB (IC5002).
Does the D5001 (red) go out?
The tuner and VSB function well. Check IC5201
and IC5211~IC5213 for trouble.
If D5025 starts flashing or stays on in red, it means
the reception condition is bad with many errors.
* Because of poor reception condition, DTV programs may be affected by the VSB out of lock (D5002 off) or reception error
(D5001 on or flashing). Possible causes include:
that signals being received by the antenna are too weak or too strong.
that received signals contain remarkable ghost and other interference.

being hooked up.
