TROUBLESHOOTING
If you experience a <no signal> with this scaler, first make certain that the signals being fed to
the inputs are acceptable.
Disconnect the cables from the scaler inputs and connect them directly to an appropriate display
device. If you do not see or hear a signal, the problem may lie in the signal source. You should
also check if the AC outlet used to power the scaler is working to provide power.
The second most common problem with this scaler comes from the cables. Inspect the cables for
loose connectors or cable damage such as crushed cable or cables with cuts or nicks. Replace
cables exhibiting any of these problems. You also must use the highest quality cables if you want
to achieve the best result. Poor quality cables result in poor quality signals.
