Center Frequency requires adjustment to range
-2.1 (+/-.1) Volts DC. See also: Center Frequency

-
Bad video input, or bad sync between inputs. Test
with no connectors on inputs 1-4, or direct from
camera to input 1. If the Toaster comes up, try
other sources on input 1, to see if the Toaster
can boot with another source than you were originally
using. If so, test your original source to be sure
it is proper RS170A NTSC video. Check cabling and
connectors, and check that all video sources are
in sync as they arrive at the Toaster inputs.
-
Remove anything plugged into the Amiga parallel
port and try again. Certain printers, scanners,
and in some cases, printer switchboxes, will cause
a "TNR" or a "Toaster Unable to
Genlock" error.
-
Toaster component cards not pressed together properly.
Remove the Toaster and make sure all sub-boards
are tightly pressed together.
-
The Toaster card is not seated in slot properly
(all models), or not in correct slot (A3000 or
A4000). Check the manual for your system to be
sure that you have the Toaster in the video slot,
and not in an ISA (PC compatible) slot. Remove
and reseat the Toaster card.
-
Toaster edge connector contacts need cleaned,
slot needs cleaned. You can clean the Toaster card's
contacts with a rubber eraser. Computer slots should
be cleaned with a cleaning solution such as ElectroWash,
which may be sprayed into the slot, and does not
require a utensil to be swept through the slot.
Alternatively, you can use 90% or higher isopropyl
alcohol as a cleaning solution on an appropriate
lint-free cloth or utensil to sweep the contacts
*very carefully*.
-
In A3000: Toaster card may be touching the top
of the computer case. Place a non-conductive insulating
material between the Toaster card and the top of
the case. A full-length anti-static bag would do
the job just fine.
-
In A4000: card may be touching the A4000 RAM.
Be sure card is supported at front of CPU by slot
guides. If necessary, place a nonconductive material
between the Toaster card and the A4000 RAM.
-
Both A3000 and A4000 desktop models: the expansion
daughtercard is loose, or faulty, or power to the
daughtercard is faulty, or the Buster controller
has failed. If you suspect this, refer to a service
center for diagnostics.
-
In A2000 with VT2000: the FCC shield bracket may
be touching pins on the Toaster card. Check the
position of the FCC bracket, and shift it away
from any pins it may be touching.
-
Untrimmed pins on the Toaster main board resistor
packs may be bent into contact with one another.
Remove the Toaster card from the system, and look
at the back of the full-length main board, at the
end of the half-height section. There are several
rows of leads (pins) protruding through the board
at this location from a number of resistor packs.
On some production units these were not trimmed
off quite short enough, and the pins may bend and
touch one another. If the leads look too long,
they should be trimmed using a small wire cutter,
to a length that does not allow them to touch one
another. When this problem has produced the "TNR" error,
trimming the leads will usually restore operation.
If the leads were in contact with one another,
but trimming the leads does not restore operation,
call NewTek Tech Support for an RMA, and be sure
you describe the condition of the pins to the technician.
-
A DCTV unit is attached. Some users report that
the DCTV can be used successfully with the Toaster,
but other users have reported having a DCTV attached
will prevent proper Toaster function; some have
even reported that they suspect attempts to use
a DCTV and Toaster on the same system have damaged
the DCTV, the Toaster, or the host system. We do
not recommend using the DCTV and the Toaster on
the same system.
-
All else fails: Toaster card is defective, call
for an RMA.
