The color is off and the figures are outlined in blue and yellow, plus the picture is cloudy looking.

Press menu on your set scroll down to where it says picture then press select. Now scroll down to convergence and press select. A white cross should appear on your screen. Your objective is to merge or converge all the crosses into the one white cross. If done right you should see only the white cross. You may see a little green and blue but don't be to picky. Make sure you read the on screen instructions on how to do this. After this you continue to the next step and you should see several white crosses across your screen. Do a convergence for each one of these crosses. Your picture should brighten up and your yellow and blue lines should go away. If it doesnt you have a bad convergence chip or some bad capacitors. If the first step doesn't fix it I would that you had a tech come and check it out.

Hi,Yes your problem sounds like the DMD board.This is how it works: Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : Have a blessed one!

Picture is scrambled after power surge. Have a

Check if it has a scrambled image on all sources ie - DVD- VCR - cable/satellite box. Since the PIP is normal it sounds like the signal source is bad.
Post back with more info about your set up (what's hooked to your TV) if you need more info

Samsung HCN4727W Rear Projection TV, green screen, audio works

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai2_bing.gif,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

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.

5 mostly green verticle lines on all digitle channels. HD ok.

I just called customer support and my issue is now fixed, to my extreme surprise.

It sounds silly (and a tad embarrassing), but here's what I did:

1) Unplug the TV
2) Wait 30s
3) Plug the TV in
4) Test

Apparently even if the TV is "off" for a few days it never fully shuts down unless the power is unplugged. Not sure if this will help anyone else, but I had the exact same problem others are describing. Good luck!

Distorted image, lines, convergence?

If the pip is fine then the digital board is bad. Have it replaced by an authorized Samsung service center as the hex settings have to be copied from the dmd to the new digital board
