Question about Toshiba 65HX81 65" Rear Projection Television

1 Answer

Large portions of the picture are off the screen in wide mode. Too much for the setting. Also my convergence has to be reset 2 or 3 times a day. The picture on occasion will "breath" in and out. And this throws the convergence way off. When I do a touch focus it goes thru the calibratin and comes back and says touch focus error.

What are the default geometry values for 480P and 1080i FULL modes?


If you have the model listed have fun----Geometry values are depicted in the Convergence section---the grid of GREEN lines determines geometry and red and blue are then adjusted to the Green.

Primitive: Set had at one time two overlays available--clear plastic you attached to screen to line the that Green grid up against---one for 480 and one for 1080.

Once the geometry is set (best possible) you must align convergence and save it in both the modes one at a time.

By current standards a Fred Flintstone system--but in its day a real pain as alignment can take many hours with the correct remote via the tech menu for convergence.

Wide screen mode won't go back to "normal".


Was exactly what you said. The cable box settings were in wide mode. Couldn't figure it out at all. Funny thing was too.. on my cable box remote, the button under the #9 button is the # button.. it doesn't say zoom at all.. but it totally controls the zoom.

So thanks for that.. AND thanks for saying "under the #9 on the cable remote" instead of just saying .. the zoom button.

Thanks again!!!

Repairman tried to set convergance but got my picture size too large. I need to know code he punched in remote to get to diag.


With the set turned on and using the original remote enter:

0, 6, 2, 5, 9, 7 and then hit Status on the remote--this will take you into the convergence mode(tech)

Instructions on the screen will tell you hit menu to adjust(you use the cursors to adjust) and Status to navigate the grid(2,4,8,6 will navigate)---when you are done hit Status 2 times and then scroll down to SAVE--save as you go.

These sets may take a lot of time to adjust--and if you have HD the set has to be adjusted separate in the HD mode.

Let me know if you have problems--I am here to help--a vote here would be nice.

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.

I have a T5054 TV and the picture has zoomed in and is way too big, however in the picture settings menu the zoom option is not highlighted in Component mode.


There could be a problem, but verify the settings as listed in the owner's manual as follows:

1 Press the MENU button to display the menu.
Press the ▲ or ▼ button to select Picture, then press the ENTER button.
2 Press the ▲ or ▼ button to select Size, then press the ENTER button.
3 Press the ▲ or ▼ button to select the screen format you want.
Press the ENTER button.
Press the EXIT button to exit.
16:9 : Sets the picture to 16:9 wide mode.
Zoom1 : Magnifies the size of the picture on the screen.
Zoom2 : Expands the Zoom1 format picture.
Wide Fit : Enlarges the aspect ratio of the picture to fit the entire screen.
4:3 : Sets the picture to 4:3 normal mode.
Just Scan : Use this function to see the full image without any cutoff when DTV
or HDMI 720p/1080i signals are input.
Press the P.SIZE button on the remote control to change the picture size.


And realize the restrictions as listed:

• In TV, VIDEO, S-VIDEO, and COMPONENT(480i, 480p) modes, all screen
modes can be selected. (16:9 ➞ Zoom1 ➞ Zoom2 ➞ 4:3)
• In COMPONENT(720p, 1080i) or HDMI(720p, 1080i) mode, 16:9, 4:3 and
Wide Fit can be selected.
• In Zoom1, Zoom2 and Wide Fit modes, you can move the picture on the
screen by pressing the ▲ or ▼ button.
•You can not change the picture size when PIP is set to Double.
•When Double ( , ) mode has been set in PIP, the Picture Size cannot
be set.
•Wide Fit can be used when watching a Digital HD (High Definition) signal.
Wide Fit sets the optimum picture format by expanding it both horizontally and
vertically. For example, you can reset the picture in 4:3 format to 16:9. Wide Fit
does not support all external devices (DVD, VCR etc.).


Keep us posted.

Yes, you have a size problem you have horizontal and vertical size. Either its' in the service mode or somewhere on the set, with this set it's probably in menu. Must be set too high. I will look for menu codes! Is this an Akai or Panasonic set?
