Make sure that the selected input source is connected to a
working component. If the other component is not working,
correct the problem with the other component.
If the RPTV is connected to a computer in RGB mode check to
see if the computer has gone to sleep and if so, press any key
on the keyboard to "wake up" the computer.
The picture is distorted or there is an
unusual sound.
Check if there is interference from other electrical appliance,
car, motorcycle or fluorescent light. Try moving the RPTV or
offending appliance to another location.

The RPTV has pixels that are always dark.
The RPTV is manufactured using an extremely high level
of precision technology. However, sometimes pixels may
not display. Pixel defect within the industry specifications
are inherent to this type of product and do not constitute a
defective product.
There is video noise or artifact on the
picture.
When the RPTVs digital capabilities exceed a digital broadcast
signal, the signal is up-converted (increased) to match the
RPTVs display capabilities. This process may cause video
noise or artifact on screen.
