3 If there is a preview image but no output image, check the

display connection. Ensure the YPrPb cables are properly
connected if using a component video TV. Some display devices
may not display the source’s output resolution (for example,
component 720p going into a standard deﬁ nition display or an
HDMI source which is preset to an unsupported resolution for a
particular HDMI display.

3 If the preview image looks good but the colors are wrong on the

component video display then check that the component cables
are properly connected. NOTE: Only a non-copy protected YCrCb
HDMI source can be viewed on a component display. Other types of
HDMI sources show either no picture or improper colors.

8 Voltage

Protection

Circuit

When the SSP-800 is connected to AC power, the AC input enters
the component through a Voltage Sensing Circuit, which checks
the voltage level every 25 milliseconds. Power can only reach the
component once it has passed the Voltage Sensing Circuit. Th

e circuit

veriﬁ es that the power is within tolerable operating levels:

3 of ±10% of its AC line voltage setting.
3 between ± 11% and 15% of its AC line voltage setting.

e following behavior of the SSP-800 is the result of the Voltage

Sensing Circuit:

3 If the external voltage is within the performance range, the

product functions normally.

3 If the external voltage enters the range of the safe operating

limit, the standby LED ﬂ ashes every half-second but the product
otherwise continues to function normally.

3 If the external voltage exceeds the safe operating limit for

10 consecutive seconds, the protection circuitry engages and
an error message appears on the touchscreen.

3 If the external voltage falls below its performance range, the

standby LED ﬂ ashes indeﬁ nitely every half-second until the
voltage is insuﬃ

cient to sustain normal operation.

3 You have to cycle power to reset the protection circuitry. If you

attempt to reset the SSP-800 while the external power supply
remains outside the safe operating limit, the protection circuit
re-engages, putting the SSP-800 back into Standby mode. We
therefore recommend that you wait until the standby LED
stops ﬂ ashing before cycling power and resetting the protection
circuitry.
