1080I Picture Not Aligned Properly (Color is FINE, not a convergence issue)

The picture is misaligned such that I can see the time-code info of the broadcast at the top of my screen and the picture at the way bottom of the incoming signal is cut off (too low to appear on the screen). It seems like all the guns are misaligned, but this does not occur when I feed it a standard 4:3 signal. The color alignment is fine. Is there a hidden way to adjust the overall picture alignment? I can't believe it's not a standard feature to be able to adjust this manually. Make: ProScan Model: PS65000 (I shouldn't have to specify this, but I see tons of people asking questions in this section that don't even have this make/model). Thanks so much, Alan

Re: 1080I Picture Not Aligned Properly (Color is FINE,...

So if the picture is short at the top and the bottom you can first try the service menu and adjust the vertical size and the vertical center. You must be very carefull when adjusting this service menu as a small mistake can make a minor adjusment become a very costly repair. Do not attempt this if you do not think you can figure it out and always always write down the values of the adjustment before you try them.Ok Heres goes. To enter service mode, push and hold the [Menu] button on the set. While holding, push and release the [Power] button, then the [Vol +] button. You will now have some information on the screen: "P0 V0" To actually be able to change these values, you must push [Vol +] on the remote so the information reads V76. Then pushing on the Channel +/- will change the "P" value. P1 - 3 are error codes. If there is a problem with the set that can be self-diagnosed, the "V" will report the code. These codes are available in the RCA repair manual.Go here to get the chart as it will not fit in this post. You really should invest in a service manual as all the info you will need will be in this manual for your set. Good Luck.

My Tv has red light (color) out of focus..I've tried tuning the lance but it's not the problem in the's something else..don't know you?

Your TV has three picture tubes which are aligned to properly converge the projected light beams on the screen. Each picture tube projects a single color of Blue Green or Red. During production your TV was carefully adjusted to properly align these colors. As a feature you have the ability to adjust these colors.thats called convergence.If you don't have a manual to show you how to adjust you can find one here

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
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
(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
(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
(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.

2003 Samsung HDTV 1080i 42" wide screen has just developed picture problems distorted and red. Almost looks 3D. MODEL NO.:HCN4226WX/XAC SERIAL NO.: 37083CEX400297E

This is a convergence problem and can easily be fixed either by resoldering the pins on the convergence ICs or by replaceing them if they prove to be defective. Can you solder? Do you feel confident in replacing these parts?
Keep us posted.

Adjust picture tubes

If all 3 crt's were replaced it sounds like something was not reassembled properly. There is a chance that the mech. focus on the crt lens need to be adjusted, or the mirror is not in the right position or it is possible that the convergence is not properly aligned. If you can send me a digital picture to: I can probably give you more info.

Wierd problem

HD projection televisions have seperate convergence alignment for 480i-1080i thus your problem when you use your XBOX360. The "No sensor data" that shows up is due to the fact that the sensors need to be initilized after doing the convergence in 1080i mode. You will probably need a technician to do the alignment because if it is out that much then a template needs to be used to get it corrected. For now you can put your XBOX in a lower display mode until repairs are done.
