5. Troubleshooting
If your monitor goes blank periodically
…
Some VCR's (particularly lower cost ones with no time-base
correction), output jittery and unstable video signal timing (especially
in FF or PAUSE modes); however, the TVB200-Plus performs the
conversion to VGA regardless. Some VGA monitors or LCD's may not
be able to handle the instability in refresh rate and may lose the image
lock periodically. If this occurs, the solution is to: use a different VCR
with time base correction (TBC), change the monitor to a different
brand/model, or use a scaler with time-base correction instead of the
TVB200-Plus (such as Hall Research Technologies’ Model TVB-350).
If you want to substitute power supplies
…
The converter relies on the AC power adapter that is supplied with it.
The adapter generates a 6v DC at 800 mA. You can substitute your
own power supply as long as it does not exceed 7.5 volts. The power
jack on the unit is center positive 2.5mm coaxial power connector.
