Question about Zenith R45W47 45" Rear Projection HDTV

1 Answer

Color is off

Have tried using the convergence adjustment. This seems to work for the red and for most of the outer numbers when using 1-9,but, blue will not adjust using bottons 2-5-8 the blue lines can be moved up or down but not to the left or right. This is causing a blue ghost like picture when watching any program...

Center the controls as best you can, disregarding the pix for the moment. Then, do a mechanical setup, getting the alignment as close as you can. Now, perform the electrical setup and see what you get. If you can't get it any closer, you'll have to address the convergence probem that we suspected you have...accordianman

My rear projection tv used to have green lines , now the color seems off and now its blue lines... How do i fix it. Color going out??


If colors are skewed or looks 3d it is a convergence problem.

Some sets when the convergence grid is called up will have green lines--green is fixed and red/blue adjusted to it.

To tell you how to fix I need to know brand and model number.

These are typical convergence problems--no two sets will look exactly the same.

Blue will not focus causing "shadows". Magic focus will not solve the problem.


This tv have a problems call convergence,it dead.The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts must be replaced to solved convergence problems.The shop will cost u $300-350 for parts and labors.

Screen hazzy and issue with blue convergence


bad convergence would cause show to look as if it was supposed to be a 3-d movie, if a bulb was going out then people would look purple blue -green,or some other off color, so likely the green bulb is going out from the color of the people you described.

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.

Green tint on Samsung Television


Hi sbatsch,

Not to worry - this problem is very common with projection TVs and is easily fixed:

The reason for the green shadows (and the resulting wrong colors) is that the three color tubes (red, green, and blue - the three colors of light that combine to form all the other colors) are not lined up exactly - this lining up is known as "convergence." You can fix convergence automatically or, if it doesn't work to your satisfaction, manually. Here's how:

Automatically:
1) Press MENU.
2) Go down to CONVERGENCE (using the up and down arrows)
3) Select it (usually with the left or right arrow)
4) Go down to AUTO and select it - the process should take about a minute.

If this doesn't work, then try manually:
1) MENU
2) CONVERGENCE (as above)
3) Select MANUAL
4) Using the number keys, SELECT, and the arrow keys, adjust the alignment of the different color crosses - the goal is to make them appear white (meaning that the red, blue, and green are exactly aligned on top of one another).

Here's a link to the JVC user manual that will explain the manual convergence adjustment in more detail.

http://resources.jvc.com/Resources/00/00/96/52105ien.pdf

I hope this helps - please let me know if I can be of any further assistance.

Convergence issue


try fixing the convergence 2 after your've aligned the convergence 1 - the second (accessed via the set up control) let's you adjust on 9 different axis to align the red and blue tubes to the green. you select which + sign you want to adust by pressing the corresponding number for the + ie 1 for the top left, and 9 for the lower right corner.

good luck (note - you cant change the green only the red and blue, if the whole edge is a mess try moving the image (you need to be in zoom mode, and then access the position adjustment via the pitcure set up screen.

ALOT OF BLUE ON THE SCREEN!!


Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
701cb04.jpg
77ea520.jpg
f0900cb.jpg
Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

2c07611.pngSolution #1

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

2c07611.pngSolution #2


What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.

Red and blue colors go across the screen. picture looks concave.


Greetings joanne7,

The issue you are having could be caused by your television needing the convergence adjusted. During production your televison has the three picture tubes that are converged to form a single image on the screen. Over time these can come out of adjustment.
If you go to this link http://download.jazel.net/misc/filecache/b8/b89bca4c8b740315d378e8ed030461c5_1227-517SeriesOwnersGuide.pdf and check pages 57 and 58, it gives you a very detailed guide on adjusting your convergence. I am aware this model number is slightly different than yours, but I own a 47" Mitsubishi and this is the exact procedure we use to do our convergence so I am confident it is fairly universal.

I hope this helps!

Dorothy
