Is the tuner built-in ATSC, or NTSC?


Your tv tuner is set to function on both NTSC and ATSC. See below for the reference

NTSC (National Television System Committee) is the analog television broadcasting standard used widely in North America. It is referred to as a 525-line standard, but actually displays only 480 lines. NTSC is to be replaced with new DTV (Digital TV) standards in the coming years.


ATSC (Advanced Television Standards Committee) creates the technical standards for the US digital television system (DTV). These standards are expected to be used in most new televisions, as the US television system shifts from analog to digital.

Uninstall the DTV Box and scart leads completley. If the box id new take it back to the store and ask them to connect it to one of their TVs or u connect to another TV in your House.

Convergence problem


This is out of the service manual

don't forget to write the setting to rom by hitting the pip button twice

Good luck and don't hesitate to ask questions






2.12.5 Convergence point adjustment
Adjustment preparation
(1) Select color to adjust.
“STATUS” - Green
“0” - Red
“ANT” - Blue
(2) Use 4, 6, 2, and 5 to move the cursor position
(dotted lines).
(3) Use thumb stick to move the convergence point.
(4) Three adjustment modes are available:
1. (3x3) Press “STATUS” 5 times (only works
when DCU is in uncorrected state)
2. (7x5) Press “0” 5 times
3. (13x9) Press “ANT” 5 times
For touch-up, only the (13x9) mode is necessary.
This will adjust every cross-hatch intersection point
on the screen.
For complete adjustment, start with (3x3) mode. This
will adjust center point and eight edge points only,
but will greatly reduce adjustment time. Then use
(7x5) mode, and finally (13x9) mode to finish
convergence.
If “S” distortion appears between cross-hatch lines
repeat (7x5) mode to change calculation process
while adjusting to remove distortion, then return to
(13x9) mode to finish touch-up convergence.
Adjustment procedure
(1) Receive any NTSC signal.
(2) Start adjustment at the center of the screen.
(3) Continue adjustment at next closest position.
(4) Adjust center area first, ending with edge sections.
(5) Press INFO button to perform calculation operation.
This process will take about 2 seconds and no
picture will be seen at this time.
(6) After interpolation, check convergence again and
repeat (1)-(5) if necessary.
(7) When convergence is acceptable, press PIP MODE
to write data to ROM memory. ROM WRITE? is
displayed to alarm system that ROM will be
overwritten with new data. Press the PIP MODE
button again to write displayed data to ROM.
(8) DATA WRITE TO ROM will take approximately 4
seconds and no picture will be displayed.
(9) Green dots will be displayed when operation is
completed.
(10) Press MUTE to return to convergence pattern, then
confirm again convergence is acceptable.
(11) Press PIP MODE (ROM WRITE) mode, then press
PIP CH to initialize sensor data positions.
Adjustment procedure
(12) Input any 1080I signal.
(13)Press EXIT key 5 times to exit video mode.
(14) Select an input with 1080i signal.
(15)Access menu and select ASPECT 5 mode.
(16)Press the SERVICE SW. ONLY button to enter to
DCU crosshatch signal.
(17)Repeat steps 2~11 above.
Notes: (1) Display only green for easier adjustment and
match to jig screen. Press “MENU”, THEN
PRESS “STATUS”.
(2) Perform interpolation and data write to ROM
after green adjustment. Once green has been
confirmed to match jig screen, the jig screen can
be removed. Do not readjust the green color
after jig screen has been removed. This is now
your reference color.
(3) Display green and red only and match red to
green.
(4) Display all colors and match blue to green and
red. Touch-up red color if necessary.
(5) Existing DATA in ROM can be read by pressing
the SWAP button 2 times. This data can be used
after replacing a component (CRT, DY, etc.)
Where complete convergence adjustment is not
necessary, be careful not to overwrite this data.
DO NOT write cleared RAM data into ROM or a
complete convergence adjustment will be
necessary. Remember to try MAGIC FOCUS
before starting convergence adjustment to
minimize adjustment time.

Dtv ready?


Going to the following link will help you to find out if your television is DTV ready or not:

http://www.dtvtransition.org/index.php?option=com_content&task=view&id=51&Itemid=94

Using their online tool, select the Brand (Akai) and the Model from the list. If you cannot find your model in the list (which I was not able to for your television), they are saying that you most likely do not have a digital tuner.

All is not lost, however. As stated on the aforementioned site, you can consider one of the following options:

  • Purchase a digital-to-analog converter box that plugs into an existing television. The boxes, which are expected to cost between $40 - 70 will be available for purchase in 2008. Beginning in February 2008, U.S. households can request up to two coupons valued at $40 each. Each coupon can go toward the purchase of a single set-top converter box that will allow you to continue watching FREE "over-the-air" television on an analog set.
  • Subscribe to a cable, satellite or telecommunications service provider if all desired local broadcast stations are carried by that service.
  • Purchase a new television set with a built in digital tuner.

    Listed on the page is further information that may help you to determine the status of your TV:

  • Consult your owner's manual. If that's not possible, you may be able to look up information about your TV set on the manufacturer's website. Or, you can take an up-close look at your TV set. You are trying to find out if your set has an input connection labeled "digital input" or "ATSC" (for Advanced Television Systems Committee, which is developing the DTV format).
  • If you bought your TV set before 1998, it probably doesn't have a digital tuner at all. Almost every TV set made before 1998 was a traditional "analog" set that can't display digital TV signals without either a special converter or a cable TV connection. If you bought a big-screen, projection TV between 1998 and 2004, it's possible there's a built-in digital tuner inside. But chances aren't great. Only a limited percentage of projection TV sets (and generally only those 42 inches in diameter or larger) included digital tuners before 2004.
  • If you've purchased a new TV set since 2004, your chances of having a built-in digital tuner improve dramatically. Starting in 2004, many of the TV sets sold at popular electronics stores have featured digital tuners that will let you receive the new digital over-the-air broadcasts starting in February 2009. But be wary: It's not a sure thing. Even some of the newer TV sets are purely display monitors that lack the internal circuitry needed to pick up digital broadcasts. Usually these sets have been advertised as "HD-ready" or "HDTV monitor" sets. That means they can display digital and high-definition signals, but they need help getting those signals in the first place. You'll still need a special converter or a cable TV connection.

    Would like to get basic channels for television without cable or satelite


    Run autoprogram on ANT mode instead of cable. As long as you're not in an area in which they shut down the NTSC early, rabbit ears or extenders should improve reception. If you are in an NTSC-early-shutdown area, you must buy a digital converter box. dtv.gov for more details.

    How do i convert my dtv-5801 to the new free digital air waves


    My information indicates that the DTV-5801 has a NTSC (analog TV) tuner built in bot not and ATSC (digital tuner). It does have HDTV inputs to which an external tuner can be connected. For Off-Air Digital TV, add an HDTV (ATSC High Definition tunner) and you are set to go. Do not buy the DTV converters, they have down converters built in and only deliver SD to the outputs.
